Sure that could be an edge, but likely only if it doesn't happen too often. E.g. people are often averse to exiting their losing trades. I think in most markets an Intuitive trader wouldn't find an easy way to profit on that because Algorithmic traders already took care of that.

And most LWers are not writing financial posts.

I think many people here go outside of LW to source ideas and bring them back here to share. I agree that there are plenty of high level discussions happening outside of LW. But I don't understand why those same discussions shouldn't also happen here.

One part of the puzzle is that most institutions are limited in what kind of assets they can buy. They are further limited by what kind of risk/return profile their investors are looking for. If you're holding government debt, it's considered pretty safe and has very low volatility. You're not going to lose that much money in any given year (but you also won't make much). For an index fund you could lose or make +/- 20% in any given year. Some institutions just can't tolerate that risk in the sense that it's not their job to take on that much risk.

There is a number of fundamental topics: shorting, different asset classes, leverage, volatility, futures/derivatives, liquidity, market making, arbitrage, hedge fund investment structure, momentum / mean reversion. It's true that for all of these you can go and read about them on Investopedia or something. But I know I personally read LW a lot and if someone explained the basics of some field I don't know much about here there's just a higher chance I'd read and trust them.

On the more advanced side: constructing trades based on your beliefs, public funds (e.g. SPY), options, finance history, most theory, macroeconomics. There are a lot more topics here for sure; it's hard to generate them on the spot.

I guess I'm also thinking that many people *do know* because they have heard some concepts being brought up a few times (not necessarily on LW) and it piqued their interest.

Thanks for taking my criticism in stride. I do appreciate you writing and often it's better to get something out there than not at all. And after all, that's how we learn.

I wouldn't say I understand finance particularly super well, which I think is part of what makes reading your post frustrating. It's not aimed at a beginner because it's not explaining the basics and isn't focusing one one concrete concept at a time. It's not building up on one idea. I guess it might be trying to show an overview, like flying over an area. But as it stands, I don't have much to hang these concepts on, so they just slide right off. I guess I'll wait until the future parts to see how it caches out.

I'm actually writing a post on finance as well right now. Hope to have it posted tomorrow. I'd be curious to hear your thoughts on it, and in particular on how it does the explaining part.

I strongly downvoted this post and now came back to write a comment now to explain why. (I think it's a good policy to explain all my strong downvotes.)

Your first post in the series was all over the place. It felt like trying to check off all the rationality boxes; something like "I fit in here, let me say some stuff". Which is may be just my perception or may be you are just a wordy writer. Anyway, I just didn't vote on that post, but I think it's important for context here.

This post is about finance which is a pretty complicated topic. A lot of things that "just make sense" don't actually work out the way you'd think. (Or have worked so recently but not historically.) So I think you have to be especially careful in describing and analyzing most types of financial strategies. This post (and previous posts in this sequence) does the opposite. It lists a bunch of ideas rapidly with minimal explanation or analysis. It feels like a flag waving for doing finance in a better and cooler way.

(However I did like Wei_Dai's summary of your post and your response to it. I think those two comments alone could be expanded to fill a post, if not a whole sequence, if you want to do it "right".)

Comment by alexei on Will OpenAI's work unintentionally increase existential risks related to AI? · 2020-08-11T21:00:22.075Z · score: 6 (8 votes) · LW · GW

Strong downvote because the question feels a bit targeted / leading. May be OpenAI is decreasing AI xrisk. May be other organizations are also engaged in similar behaviors that increase AI xrisk. I think a better approach would be to break things down into:

1) What factors affect AI xrisk? (Or, since that's pretty broad, have specific questions like "Does X affect AI xrisk?") (E.g. "How does pushing the state of the art of capability research affect AI xrisk?")

2) Have specific questions about OpenAI actions / traits that can be relatively easily grounded. (E.g. "How would you rate the quality of the OpenAI safety team?")

It's easy enough for people to put #1 and #2 together, but it has the added benefit of people using answering #1 without targeting any specific company. Plus answers from #1 apply to other organizations.

I was learning a bit of piano last year too, and found it very motivational to try to write my own songs. Even as a completely beginner and basically through pure trial and error, it was very fun. Then when I learned bits of theory it was nice to view my songs through that lens and see what resonated. (E.g. "ah that's why this key sounds nice here: because it's following the major scale I'm in")

Oh, and I strongly second the "play the songs you want" approach. It's so much more fun than trying to learn what you "should".

I'd consider adding exposure to specific company candidates most likely to participate / benefit from AGI, namely: Google, Microsoft, IBM, Amazon, etc...

Also, since you're betting on a pretty drastic outcome, which is very likely not priced in correctly into the markets*, you should consider buying options instead of stocks. The cost to you is much cheaper, it's easier to get more leverage, and they payout is much bigger for the extreme cases (in your favor).

* I gave a talk that touches on this point recently. The transcript should be up in the next few weeks.

Wow, that's very cool! This is actually the closest existing thing to Arbital I've heard about. I guess to Eliezer's point, it does sound like they built this system in one go, without doing much of MVP-kind of iteration. But also... damn! From the sound of it, there are a lot of complicated components, and a lot of manual work that went into the whole thing. If those are the minimum requirements to build something like that, then I'm not sure we ever had a chance.

But the good news is: if this really works, then I think Arbital is totally doable and would be just the online version of this. The remaining difficult part would be monetization, but in retrospect it's quite possible Arbital should have been a non-profit.
