I like working out of both Stanford and Constellation, because my econ-of-AI views are usually “right in between” the views of the people I respect in the singularitarian community and the people I respect in the economics community. Of course, the communities I happen to have wound up part of probably largely determine what my views are in the first place. But I do think it's an interesting sociological fact that there seem to be fewer people with something like my "in between" views than people at either extreme.
It’s funny to use the term “right in between” when the poles are so distant, but concretely--
On the technological question of whether by, say, 2040 we'll get superintelligence [machines that can shortly thereafter cure death, develop atomically precise manufacturing, solve or dissolve ~all our perennial philosophical disputes, and tell us how to quickly build von Neumann probes that put Dyson spheres around the stars]: For my singularitarian friends this is the default outcome of the trajectory we're on, and 2040 is late. For the economists (like almost everyone else), even contemplating this stuff is nutty. I give it a 10-20% chance.
On GDP: For my singularitarian friends, building fully humanoid bots (which I do think is more likely than not by 2040) will be analogous to a return to a Kremer (1993)-style Malthusian world in which GDP grows ~hyperbolically (so, with the growth rate itself rising to infinity). The economy, on this view, will ultimately grow at the rate at which robots can multiply, which is bounded below by the rate at which octopuses can multiply, which is 250,000x/yr. For my economist friends, humanoid bots would just be another step in the ongoing process of automation sustaining 2-3% growth. My central guess is that preferences for humans in some domains; nonhomothetic preferences for new goods (see
drive.google.com/file/d/1Gm-…, "New goods Baumol"); and regulation will all meaningfully constrain growth from the octopus baseline, so that this century contains "only" around 1 more OOM increase in the GDP growth rate, to ~20-30%/year.
Likewise, on real interest rates: central guess is their peak "steady state" this century is not >25 million %/yr, but ~30%/year
On wages: Singularitarians tend to think they'll fall to ~0; economists tend to say they'll grow roughly as fast as the economy at large; I think they'll rise but not as fast as the economy (so that the labor share will fall a lot)
Etc.
I think the reason is just that the communities somewhat seal themselves off from each other, so the insights from each take a while to seep through to the other. This doesn't mean that they're both doing something wrong--maybe one of them is just a cult (a majority too can be in a cult!) and the other shouldn't be updating toward them at all--but I do think it means that at least one of them is doing something wrong. Without going full "Aumann's theorem", I think that even without common priors or common knowledge of rationality, an environment with healthy information flow would usually exhibit single-peaked distributions of opinion on these sorts of questions.
