GDP per capita in 2050

This looks cool and I  want to read it in detail, but I'd like to push back a bit against an implicit take that I thought was present here: namely, that GDP takes into account major technological breakthroughs. Let me just quote some text from this article: What Do GDP Growth Curves Really Mean? [LW · GW]
 

More generally: when the price of a good falls a lot, that good is downweighted (proportional to its price drop) in real GDP calculations at end-of-period prices.

… and the way we calculate real GDP in practice is to use prices from a relatively recent year. We even move the reference year forward from time to time, so that it’s always near the end of the period when looking at long-term growth.

Real GDP Mainly Measures The Goods Which Are Revolutionized Least

Now let’s go back to our puzzle about growth since 1960, and electronics in particular.

The cost of a transistor has dropped by a stupidly huge amount since 1960 - I don’t have the data on hand, but let’s be conservative and call it a factor of 10^12 (i.e. a trillion). If we measure in 1960 prices, the transistors on a single modern chip would be worth billions. But instead we measure using recent prices, so the transistors on a single modern chip are worth… about as much as a single modern chip currently costs. And all the world’s transistors in 1960 were worth basically-zero.

1960 real GDP (and 1970 real GDP, and 1980 real GDP, etc) calculated at recent prices is dominated by the things which are expensive today - like real estate, for instance. Things which are cheap today are ignored in hindsight, even if they were a very big deal at the time.

In other words: real GDP growth mostly tracks production of goods which aren’t revolutionized. Goods whose prices drop dramatically are downweighted to near-zero, in hindsight.

When we see slow, mostly-steady real GDP growth curves, that mostly tells us about the slow and steady increase in production of things which haven’t been revolutionized. It tells us approximately-nothing about the huge revolutions in e.g. electronics.

I think there's a good chance the degree to which the world of 2050 looks different to the average person might have very little to do with GDP.

On the one hand, a large chunk of the GDP growth I expect will come from changes in how we produce, distribute, and use energy and chemicals and water and food and steel and concrete etc. But for most people what will mostly feel the same is that their home is warm in winter and cool in summer, and they can get from place to place reasonably easily, and they have machines that do their basic household chores.

On the other hand, something like self-driving cars, or augmented or virtual reality, or 3D printed organs, could be hugely tranaformative for society without necessarily impacting GDP growth much at all.

Survival vs self-expression: Survival values prioritize security over liberty. Those with survival values tend to be more homophobic, uninterested in political action, distrustful of outsiders, and less happy. As people transition from industrial to knowledge societies, their sense of agency increases and they move towards self-expression values. 

To me, the empiric status of that claim feels quite unclear. Is that your personal opinion? Is it a general pattern for which there's existing data?
