How long before driverless cars will be for sale in the U.S. outside of big cities? I'm thinking of getting a new car but wondering if I should wait or lease because of the possibility of getting a driverless car in a few years.

Within four years, Google hopes to have the autonomous vehicles commercially available and citizens throughout the U.S. regularly riding in them, Urmson said.

Google Inc. threw the auto industry another curve ball Wednesday, saying its autonomous cars should be on public roads within five years without having to drive through a thicket of regulatory red tape.

Both sources are from 2015, the first one from january, second from last week. I think it unlikely (<10%) that they are going to overperfom by more than a single year, and very likely (70%) to take at least a year longer.

Remember, its not only a technological problem, but the inertia in a vast system. Insurance+lawmakers etc need to finish their side as well.

Elon Musk, someone who can reasonably called domain expert on innovative car systems, gives the same range:

The three-year estimate, Musk says, is when he thinks the technology will be ready. It could take longer for government regulations around the issue to go into effect. He acknowledged that it will take time for regulators to say "it's okay to go to sleep in the car" -- maybe another one to three years.

Note that I only looked up Musks opinion after I wrote the first part.

Depends on how long is your "few", but note that you'll need for the driverless cars to not only become available to the public, but also stop being bleeding-edge expensive. Look at Teslas -- they are available to the public, but they are not cheap.

I should look into this. But if cars quickly lose value for rational reasons, such as people only selling recently bought cars if they are defective, than I don't necessarily gain by buying a used car.

I would certainly want a good explanation of why a very-nearly-new car was being sold, and indeed I think rather few used cars are very nearly new. For a car that's at least a couple of years old, though, there seems little need for extreme suspicion, and so far as I know (note: I have no statistics on this) most used cars are not horribly defective, suggesting that hugely reduced price relative to new cars can't be mostly about the risk of such defects. (If the used car is half the price of the new one, it would need something close to a 50% chance of being completely worthless for defect risk to justify the price difference. Somewhat less than that, of course, on account of inconvenience and the fact that an unknown defect is worse than a known one, but I think not hugely less.)

I suspect (with no evidence beyond casual observation) that it's mostly a combination of:

Risk aversion. If you buy a new car, you can be pretty confident that it's in good working order (and have recourse if it turns out not to be). If you buy a used car, usually it's fine but there's a nonzero chance that you get screwed.

It seems to me that most people are too risk-averse, in the sense that if they were able to disvalue risk less then (1) most would be happier overall and (2) aggregate happiness would be greater. If you are less risk-averse than most, you might value used cars higher relative to new ones.

Laziness. Reducing the risk of buying a lemon requires effort (and maybe getting help from someone else more expert).

If you don't value your time at hundreds or thousands of dollars per hour, you should probably not see this as a compelling reason for buying a new car.

Signalling. If your car is intended (on some level) as a signal of what a nice car you can afford to drive, then a shiny new one is a better signal than a used one.

If you care less about signalling, or want to signal other things than willingness to spend, you might value used cars higher relative to new ones.

Sheer attraction to shininess. (Broadly understood.) New cars look nice. Buyers who don't think explicitly about how much they value such things may be willing to pay many thousands of pounds/dollars/euros for this.

My guess is that scarcely anyone would defend this after considering carefully what they're actually paying all that money for. (You can buy a lot of other nice shiny things for the difference in price between a new car and a merely newish one.)

You will gather from the spin on my comments that I am firmly in the "buy 'em used" camp. If you are more risk-averse than I am, value your time much more than I do mine, are keen to signal wealth, and find shiny cars especially attractive, then you may very reasonably make a different decision.

f the used car is half the price of the new one, it would need something close to a 50% chance of being completely worthless for defect risk to justify the price difference.

No, it would not. Part of the price difference is just depreciation; the car isn't going to last as long, will need repairs sooner, etc. simply because it is older, and older cars are like that. The further price difference on top of that is the price difference that actually needs to be explained by the increased risk.

I think you've misunderstood me; my apologies for not being clearer and more explicit. I'll try to fix that below.

The question I was trying to address was: How much of the explanation can defect risk be? And my answer was: Not much more than the expected cost of the defects, which in turn is probably rather less than Pr(serious defects) * value of car without defects, which for not-very-old cars is empirically quite a small fraction of the cost of the new car.

(The "used price = new price / 2" case was just an example.)

Since the difference between new and used prices is a large fraction of the cost of the new car, therefore, it seems unlikely that defect risk is most of the explanation -- as I said,

suggesting that hugely reduced price relative to new cars can't be mostly about the risk of such defects.

The context was James Miller's suggestion (if I understood him correctly) that defect risk might in fact be a large fraction of the explanation for the big difference in price between new cars and used-but-not-very-old cars.

comment by Jiro · 2015-09-08T01:58:44.055Z · score: 0 (0 votes) · LW · GW

I don't think that's wrong, but I have another suggestion: Car prices may be subject to a variation of Goodhart's Law. Defects may not be that likely in used cars, but attempting to act as though they are not likely would create incentives that would make them become likely.

This might require precommitment or superrationality on the part of the consumers, but a lot of "irrational" consumer behavior can be modelled as rational precommitment, even if the consumer doesn't consciously realize that's what it is.

That's a very interesting idea. I'm pretty sure it's too sophisticated to be consciously part of the reasoning of more than a tiny fraction of car buyers, so if it's an important part of the explanation it must be (as you suggest) unconscious -- presumably as a result of some general-purpose unconscious tendency to over-penalize risks of that general sort. This suggests some interesting psychology experiments; I wonder whether they've been done.

Is it useful to think about the difference between 'physically possible' i.e. obeying the laws of physics and possible to engineer? In computer science there is something like this. You have things which can't be done on a turing machine (e.g. halting problem). But then you have things which we may never be able to arrange the atoms in the universe to do, such as large cases of NP-hard problems.

So what about in physics? I have seen the argument that if we set loose a paperclip maximizer on earth, then we might doom the rest of the observable universe. But maybe there is simply no sequence of steps that even a super brilliant AI could take to arrange matter in such a way as to say move 1000kg at 98% the speed of light. Anyway, I am curious if this kind of thinking is developed somewhere.

We know, and can formalize, what the upper limits of computing are. We have no idea what the upper limits of physics are. Even if we assume we know all the things there are to know about physics, that doesn't mean clever engineering can't come up with a way of doing it.

Even if you only move at a fraction of the speed of light, you could reach all the stars in a galaxy in a few million years. In the 1960s engineers came up with a way of travelling 1-10% of the speed of light using nuclear bombs. There was another proposal IIRC that used a giant collector in the front to grab hydrogen molecules, and could somehow reach 70% of the speed of light.

If you have nanotech, you can shoot millions of very tiny, pin sized or smaller, spacecraft at significant speeds. Even if only a tiny fraction reach their destination, the nanotech on board could self replicate, and create trillions more.

Colonizing the galaxy is a political problem, not a question of engineering possibility. A sufficiently zealous world government could jump-start asteroid mining with an Orion Heavy Lifter, construct mirror arrays near the sun, and start lobbing around interstellar VNMs, all with relatively simple refinement and application of existing technologies. Problem is, the best way of putting a complete industrial base into orbit runs afoul of certain atmospheric nuclear test ban treaties.

Without a reactionless drive there's no point sending a colony ship faster than about 60% of the speed of light. Gotta save some remass to decelerate.

Can we use the stock market itself as a useful prediction market in any way? For example can we get useful information about how long Moore's law type growth in microprocessors will likely continue based on how much the market values certain companies? Or are there too many auxiliary factors, so that reverse engineering anything interesting from price information is hopeless?

I don't think I understand how that is consistent with EMH. You mean that P:E predicts high variance but the mean is still priced in correctly so one can't make a profit just by looking at P:E? A high P:E meaning something like the market saying 'this company's earnings will either go way up or way down but I don't know which'?

Imagine that the stock prices of companies A and B were equal. Last year Company A had low earnings per share while company B had high earnings per share. EMH implies that the market expects that in the future Company A's earnings will increase relative to Company B's earnings.

EMH implies that stock prices, not profits, follow random walks.

Say both of our businesses made $1 million this year. Everyone expects your profits to increase but mine to decline. We have the same number of shares of stock outstanding. Your company's stock price will be a lot higher than mine, giving you a much greater price/earnings ratio reflecting the market's expectations of increases in your future profits.

The claim that the market is good at predicting future earnings.

It probably is, but economics does not yet have the empirical grounding to give me high confidence in its theories (the way I would be for fields like physics or chemistry; I still think economic theory has a strongly positive correlation with reality).

The claim that the market is good at predicting future earnings.

This is conceptually very easy to test; get historical stock price and earnings data, compute P/E ratios at each snapshot, compute earnings growth across snapshots, and then look at the relationship between the two. Vanguard ran the numbers here (page 7), and two ways of calculating the P/E ratio were the strongest two factors. (As one would expect, 1-year returns were very difficult to predict at all, and they were mostly useful for 10-year returns.)

If I've understood that document correctly, they aren't saying anything about predicting performance of individual companies, they're looking at some sort of averaged P/E ratio and relating it to future performance of the stock market as a whole.

One way for that to work would be for individual stocks' P/E ratio to be indicative of their future performance, but there are others; e.g., maybe overall economic conditions influence both investors' attitudes and future performance. In the latter case, P/E ratio might be less useful (or outright useless) for comparing companies at a single time.

comment by Vaniver · 2015-09-08T13:29:28.102Z · score: 1 (1 votes) · LW · GW

Agreed. I went with the first Google search result that was at all close to the question at hand; I recommend anyone more interested in the subject collect the data and run the numbers themselves.

In particular, one might want to compare residual P/E ratios--that company's P/E minus the S&P 500's P/E or the total stock market P/E--to future earnings growth in order to try to remove some of the time-dependent effects and specifically judge the market's ability to guess the earnings growth of individual companies.

One could, if they knew historical industrial groupings, judge the market's ability to price the overall market, industries, and individual companies. It seems like we would expect the first to be better than the second, which is itself better than the third. This is both for the raw statistical reason that the sample being averaged over is smaller as we go down, making the range of reasonable numbers larger, and the financial reason that forces on larger scales may be more visible or predictable than forces on smaller scales.

No, companies are too complicated. To address your particular example, Intel has three advantages over its competitors. One is that it pushes the boundary of Moore's law, the one point you are interested in. But the other two are that it is probably the best in the world at arranging transistors and that it has close to a monopoly on the 386 architecture, and thus inertia. Even if Moore's law did break down, it is not clear how long it would take for the competitors to catch up.

That's an interesting offhand comment. Does that imply that EMH doesn't apply to financial assets in corrupt economies, specifically to external (foreign) investors who can come and leave as they want?

Also, while China's official economic numbers are highly suspect (see e.g. this), it looks very likely that it is one of the three world's biggest economies (along with USA and EU). Can a passive investor afford to ignore it?

To help mitigate the currency risk of investments?

Well, it doesn't mitigate the risk, it just partially avoids it. You are right in that investing in foreign countries brings with it FX risk and while it's easy to hedge a lot of people are not going to bother.

The currency rates are not a random walk (it's easy to verify that emprirically) either before or after adjusting for the interest rate parity.

What makes currency markets different is that they have huge powerful players -- central banks -- which are not driven by the profit motive.

I use Mint.com to great effect. It's free, it allows you to track all your bank accounts and investments and any property you care to keep track of. It also lets you set budgets.

It doesn't do anything for tracking time.

If you use it you will inevitably find shortfalls. For example, you will inevitably wish that you could apply this month's budget assumptions to previous months in order to test out the budget's performance, and you'll realize that you can't do that. But all software has limitations.

Yes; informal and crowdsourced ones where you can download and use without restriction include:

Probably a lot of overlap between them, though, so you would need to de-duplicate.

Various scientific/professional genome datasets are available; for example, https://en.wikipedia.org/wiki/1000_Genomes_Project makes their 1k genomes available (but lacks any phenotype data). I don't have a complete list of those and probably a lot of them would put a lot of barriers in the way of access. You could look at https://en.wikipedia.org/wiki/Category:Human_genome_projects but don't expect much: privacy and 'medical ethics' and 'publish or perish' are why we can't have nice things, and why there's only a few thousand public genotypes even though we must be well past the million mark by now, considering 23andMe has done 700k+.

(I compiled this list of open DNA sources because I was curious about the possibility of checking for dysgenic trends by downloading all of them and then correlating the Rietveld SNP hits with reported age; as they have some of the largest effects and there's 7+ of them now, I figure that if the postulated dysgenics effect of the better educated reproducing less was true, then it almost surely has been decreasing their frequency over the past few generations. 1000 Genomes is useless because they deliberately omit phenotype data like age, but I've already verified that there are a few hundred genomes in PGP with age/birthdate data, which may be enough. Still need to do a power analysis/simulation to see if it's worth bothering.)

How does a rationalist determine the value of helping other people they don't know, i.e. why is QALY something worth maximizing? Is it an efficient and sustainable way of improving one's own quality of life because (a) humans have empathy built-in and (b) philanthropy is a socially rewarded meme?

Some people may make arguments for morality based on things similar to Coherent Extrapolated Volition. I don't find those arguments convincing. I help people I don't know because when I think about the alternatives, I prefer the world in which one fewer person is suffering to the one where I'm better off in whatever way (e.g., I have more money in my bank account) because I didn't help. That preference is based on empathy, which was evolved, but I don't particularly care where it came from. At some point that preference gets outweighed by selfish preferences, which is why I haven't given all of my money away.

I don't think maximally helping others is a particularly good way to maximize your own quality of life unless you already want to do that. Both (a) and (b) are true, but if your goal is maximizing your own quality of life you're almost certainly going to do better if you focus on that directly. At least, in my particular case, there's some amount of warm fuzzies I get from helping people and from identifying as someone who tries to effectively help people. So in that way my quality of life is improved. But I think that if I wanted to I could get that amount of fuzzies at a lower cost.

Perhaps there is also an intrinsic motivation associated with it. If you make the world better, it's just nicer; perhaps just as cleaning your desk or backyard or sharpening a box of pencils.

It's an investment.

When you have some asset that you don't immediately need, and somebody else would be able to make better use of it, renting it out or giving it away enriches the whole system. Then you get to live in that richer system and enjoy the benefits. Your quality of life is better when you live somewhere with reliable electricity, uncensored internet, and trivial access to potable water, right? A fancy car isn't much fun without fuel or decent roads.

Helping somebody on an altruistic basis is just another transfer of resources toward where they'll be used more efficiently. It's less directly profitable to the donor than sale or rent, but reduced transaction costs and targeting explicitly based on need means the net societal benefit can be greater.

Maximizing overall QALYs may be, in itself, a less efficient way to improve the society you live in than slanting toward helping your immediate social circle, municipality, or nation, but it's easier for everyone to agree on, and every dollar or man-hour spent on arguments is one less to spend on getting the actual work done. Besides, we live in a world where more of the mercury contaminating fish in Lake Michigan comes from industry in China than from local sources. You never know whose problems might land in your back yard, so just go ahead and solve all of them.

All that social stuff, instinctive empathy and cultural expectations alike, is secondary. It developed so people can do the right thing without needing to understand why it's the right thing.

"Let's help everyone equally, or in proportion to their needs or something" is easier to agree on than "let's devote the entire GDP of Russia to my personal enjoyment, and maybe my friends and allies in proportion to their loyalty." With the former, people quibble over definitions and in-groups and details of implementation; the latter, even Putin dares not propose openly.

I'm not claiming that propensity to charity or altruism causes, or even particularly correlates with, economic development. I'm just saying that economic development is good, and that it's marginally better for the world economy when some excess food goes to a human who'll eat it, rather than sitting in some warehouse until it rots, even (perhaps especially) if the human in question can't afford to buy food at the going market rate. When rational people see something being squandered, they prefer to throw that resource into charity, where it will do some good, rather than preserve the wasteful status quo.

Or you are so unfocused you solve none of them?

You start with the especially vast, horrific problems which can be sorted out cheaply, like scurvy and polio and malaria, then proceed to more complicated, less severe stuff as returns begin to diminish.

Your last point strikes me as a truism and distraction. The question is what motivates overall QALY maximization. Parent's point was that resources should be used where they can most effectively increase QALY, and that possibly comes down to both intrinsic motivation (I don't need it, they need it, it just fits nicely) and extrinsic motivation (direct reward through hard-wired empathy and social reward through philanthropy meme).

a couple of obvious problems with this worldview

1: THIS IS NOT INVESTING. If there is no profit, if there is no business or outcome you're specifically getting paid to achieve, you have no guarantee of making the world better in any concrete way. When you invest in a factory, and that allows the factory to buy a new widget-maker which increases profits and pays you dividends, you are causally and concretely part of making the world a better place. When you give money to a hobo, no matter how sympathetic he looks or how convincing his cardboard sign is, maybe he's increasing his quality of life for the next 10 minutes by buying a sandwich, but he's NOT decreasing worldsuck in any systematic way.

  1. "so just go ahead and solve all of them." This is moronic. Paying for bednets in Africa, the most obvious EA QALY maximizing frontrunner or whatever, has no impact on mercury in Lake Michigan! You have to pick and choose what you do because you CAN'T do everything.

Capitalism sets up rules based on practicality and repeated interactions between people, which means that they actually make sense to follow even if you are purely selfish. In a system where the rules are based on empathy or ideology, the psychopath will have ZERO desire to follow the rules if they won't get caught, but because interacting peacefully in trade with people actually pays off they get incentivized not to just do whatever they might impulsively want.

Because you don't generally get to DECIDE to be a baron? You can inherit one, in which case a psychopath can to a large extent do what he wants with it without suffering repercussions, you can be granted one by the king (which is at least SOME sort of incentive system), or you can get a bunch of random guys together, start and army, and take one. At which point you can usually do whatever you want with it.

The heirs in question were only three of a series of executions of potential rivals that would have made Ivan the Terrible feel like a bit of an underachiever; it began with a mass-execution after a rebellion by two puppet rulers installed by the shah in question, although we can't count their numbers, since they weren't, for our purposes, political enemies.

The long and short of it is this: In capitalism, "Cooperate" has a higher average long-term rate of return. In other economic systems, "Defect" has a higher average long-term rate of return.

The USSR encouraged defection; just look at how, whenever food production was particularly problematic, the USSR would briefly swap over to a semi-capitalist system for a few years, and miraculously food production would increase. The farmers routinely defected under the soviet economic system, hiding whatever they could to sell on the black market, and meeting the bare minimum for the quotas, where they didn't get the quotas reduced for hardships which were always somehow worse when they didn't own the product of their labors.

Same thing with Mao's China.

It happened multiple times. The 1920 were the initial collectivization period, which led to a famine. The mid 1930's had the first semi-capitalistic change, allowing privately-held sections of farmland. The Soviet government largely ignored the fact that most effort was concentrated on the privately-held sections initially, but gradually cracked down, causing harvests to decline again. In the 1950's, some of the privately-held sections were collectivized in a renewed collectivization effort (which also combined many of the farms), and immediately harvests started falling, so the Soviet government switched from "national" ownership of the farmers' products to a system in which the government paid the farmers for the harvests. Harvests went up again. The government, however, gradually reduced payments, which again, caused harvests to plummet. In the late 60's the privately held sections of farmland were expanded, and harvests increased again. In the 70's, a new system which was supposed to guarantee farmers a higher share of the profits for their work was instituted.

Yeah, this happened constantly. Every new Party Leader wanted to make communism work, and would roll out a new communistic farming approach. This approach would fail, and they'd put some kind of capitalism back in place, and farming output would increase again.

I don't think that was as routine as you seem to think. If your farmers collective grows wheat, who do you sell it to? It's not like there were any millers to whom one could come with a sack of grain...

What makes you think there weren't? The black market in the Soviet States was all-encompassing. The millers you came to were millers for the state, even, who didn't mind getting a little bit of money on the side. Corruption, in the Soviet, was not merely a way of life, it was often necessary to survive.

"Not defecting."

That implies the Prisoner's Dilemma context. I don't see how large and complex socioeconomic systems (e.g. capitalism) are -- or can be reduced to -- a Prisoner's Dilemma.

It happened multiple times. The 1920 were the initial collectivization period, which led to a famine. The mid 1930's had the first semi-capitalistic change, allowing privately-held sections of farmland.

Nope. The 1920's were a kinda-retreat from communism because Russia was uncertain it could survive -- see NEP. The forced collectivization came afterwards, at the very end of 1920s.

I don't see any retreat from the collectivization in the mid-30s. In fact, mid-1930s is the time of the Stalin's regime going into the full-paranoia mode and tightening the screws.

In the 1950's, some of the privately-held sections were collectivized in a renewed collectivization effort

Links, please. There was "re-collectivization" on the territories temporarily lost to the Germans, but I don't think that's what we are talking about.

In the late 60's the privately held sections of farmland were expanded, and harvests increased again.

That's not inconsistent with implementing a semi-capitalistic approach, it fact one theory I've herd is that the point of "tightening the screws" was to arrest any party official, how was indiscreet enough to point out that the new policy wasn't exactly communist.

Kinda, but it has nothing to do with capitalism. One of the traditional explanations for the purges of the 1930s was the necessity to get rid of "old bolsheviks" who were too idealistic and insufficiently obedient to fit into Stalin's Russia. That wasn't because Stalin was becoming a capitalist, that was because Stalin was becoming a dictator.

The link doesn't support your claims. There was no "renewed collectivization effort" in the 1950s, what happened was that small kolkhozes were merged into big ones. And the increase in "private plots" is the increase of the size of personal gardens, basically -- don't think they can be properly called "privately held sections of farmland". People certainly used them to grow and partially sell produce, but everyone had to have a day job anyway. These private plots, as far as I know, always existed and post-WW2 only expanded. I don't think they were ever rolled back -- there was no back-and-forth waves.

Is is true that the USSR gradually relaxed its grip on the peasants compared to mid-1930s, but, again, it was a continuous trend, there was no back-and-forth. Once the peasants got internal passports, they were not taken back. Once they started to be paid in money for the harvest, that continued and did not roll back, etc.

Given your previous assertion that it didn't happen at all, I think you're generally taking a position much stronger than your evidence supports, which is to say, you're treating all of my claims as false until proven true. Consider updating on the possibility that I do have some idea what I'm talking about, in addition to updating on the specific points.

Google "size of private kolkhoz plot", however, for a variety of sources. Yes, there was -considerable- back-and-forth. And yes, once they started paying money, they continued - but the amount of money -did- vary, and it frequently didn't cover the cost of production.

It seems that we have very little data about a huge structure, so fitting any model to it at this point might give us a fairly large margin of error (especially since we extrapolate from a theory that we know that is incomplete).

It's better to think about the Big Bang as an admission of failure: using our best stitching of the two best theories that we have about the universe, and extrapolating back the data at hand as further as we can, we arrive to a point where our description breaks down (the singularity).
Will a better theory cast a brighter light on this point in space-time? I assign a 99.9% probability that it will.
I think that only the most zealot between relativists bite the bullet that inside a black hole there's actually a point where the gravitational field reaches an infinite value. And given that the more time passes the more paradoxes we discover about black holes, I'd say that quantum gravity will revolutionize our understanding of singularities. So my probability to Big Bang actually happening is 0.1%

That there was a finite time in the past in which all matter was squeezed tight and hot enough to undergo primordial nuclear reactions, and that the universe has expanded since, is pretty dang incontrovertible at this point. The nature of that event is still up for debate. Examining the fine details of light of different ages continues to reveal things, like the expansion appearing to initially slow followed by accelerating which is currently best explained by a dark energy model which is also favored for reasons relating to physical models of space I am unprepared to examine.

The fallacy is in the use of the word "evolved."

If you take a random sampling of ten thousand modern humans and scatter them across an undeveloped planet, what will happen is basically:

  • The ones who live in horrific environments will barely manage to survive and fail to develop technologically.

  • The ones who live in environments with plentiful game and foraging availability but with minimal agricultural potential will not perceive any pressure to drive innovation.

  • The ones who live in environments most conducive to agriculture, with a harsh enough climate that saving food for the winter is a good idea, will eventually develop agriculture.

The selection pressures on technological development work orders of magnitude faster than the selection pressures on intelligence.
