- Dare I call this the Lump of Intelligence fallacy, after the Lump of Labor fallacy?
Yes, Tyler Cowen is implicitly assuming that intelligence has a fixed demand, but in fact probably has unlimited demand, and thus the value of intelligence in general will always be high, especially in advanced economies.
Maybe the central disagreement with Tyler Cowen's model here is I basically think population growth is a huge component of how GDP/technology grows in general, and I believe Tyler Cowen is basically wrong here:
(3:55) Tyler is asked wouldn’t a large rise in population drive economic growth? He says no, that’s too much a 1-factor model, in fact we’ve seen a lot of population growth without innovation or productivity growth.
I'd say this would increase GDP by quite a bit, but then somewhat revert to normal (at a new higher growth rate. Again, I disagree with Tyler Cowen here.
(10:15) Dwarkesh asks, what would happen if the world population would double? Tyler says, depends what you’re measuring. Energy use would go up. But he doesn’t agree with population-based models, too many other things matter.
The central disagreement, IMO is I genuinely disbelieve Tyler Cowen on what would happen if the population increases, and I trust economic models more saying this could well cause superexponential growth than Tyler Cowen here is, combined with me disagreeing about the value of intelligence in general for very advanced economies.
Seperate from my comment on Tyler Cowen's model, I wish that next week, you covered Adam Brown's podcast in full, since I would like to hear your thoughts about Adam Brown's scenarios for how we could change physics.

Yes, economics after von Neumann very much turned into a game of "don't believe in anything you can't already comparatively quantify". It is supremely frustrating.
On that note, I’d also point everyone to Dwarkesh Patel’s other recent podcast, which was with physicist Adam Brown. It repeatedly blew my mind in the best of ways, and I’d love to be in a different branch where I had the time to dig into some of the statements here. Physics is so bizarre.
You just inspired me to go listen myself. Maybe we should all take a node out of that branch. Unfortunately physics has suffered similar issues.

I disagree that this is a problem that Tyler Cowen has, and IMO, the main issue here is that Tyler Cowen doesn't really seem to believe that increasing the supply of workers increases GDP, especially if you can make them very cheaply and easily, in a way that is inconsistent with other beliefs, which makes me think motivated reasoning is going on here.
Economic models like the Solow-Swan model do have an implication that if the population increases, especially if the population can increase very rapidly due to copying something, then GDP can rise really rapidly on an superexponential trajectory.

Physics's main issue is that the free tap of data in the 20th century wasn't unlimited, and now that we have completed the standard model, a lot of the theories that predicted new stuff hasn't shown up yet.
Yet it still has made progress. For example, while supersymmetry might still be true about our universe, it cannot solve the hierarchy problem, and thus at least 1 of the constants is way more unnatural to us than people predicted, and also we have hints that dark energy is getting weaker, and might eventually weaken so much it falls to 0 or a negative number.
Cowen, like Hanson, discounts large qualitative societal shifts from AI that lack corresponding contemporary measurables.
Einstein was not an experimentalist, yet was perfectly capable of physics; his successors have largely not touched his unfinished work, and not for lack of data.

While it is interesting at first glance, some caveats are called for here.
One, Einstein's achievements were sort of overrated, see these comments for details:
Two, the EPR paradox is resolvable in modern physics by allowing non-locality in entanglement, but having a no-communication theorem that prevents exploiting it to break special relativity.
I didn't say he wasn't overrated. I said he was capable of physics.
Did you read the linked post? Bohm, Aharonov, and Bell misunderstood EPR. Bohm's and Aharonov's formulation of the thought experiment is easier to "solve" but does not actually address EPR's concern, which is that mutual non-commutation of x-, y-, and z-spin implies hidden variables must not be superfluous. Again, EPR were fine with mutual non-commutation, and fine with entanglement. What they were pointing out was that the two postulates don't make sense in each other's presence.
Dwarkesh Patel again interviewed Tyler Cowen, largely about AI, so here we go.
Note that I take it as a given that the entire discussion is taking place in some form of an ‘AI Fizzle’ and ‘economic normal’ world, where AI does not advance too much in capability from its current form, in meaningful senses, and we do not get superintelligence [because of reasons]. It’s still massive additional progress by the standards of any other technology, but painfully slow by the ‘AGI is coming soon’ crowd.
That’s the only way I can make the discussion make at least some sense, with Tyler Cowen predicting 0.5%/year additional RGDP growth from AI. That level of capabilities progress is a possible world, although the various elements stated here seem like they are sometimes from different possible worlds.
I note that this conversation was recorded prior to o3 and all the year end releases. So his baseline estimate of RGDP growth and AI impacts has likely increased modestly.
I go very extensively into the first section on economic growth and AI. After that, the podcast becomes classic Tyler Cowen and is interesting throughout, but I will be relatively sparing in my notes in other areas, and am skipping over many points.
This is a speed premium and ‘low effort’ post, in the sense that this is mostly me writing down my reactions and counterarguments in real time, similar to how one would do a podcast. It is high effort in that I spent several hours listening to, thinking about and responding to the first fifteen minutes of a podcast.
As a convention: When I’m in the numbered sections, I’m reporting what was said. When I’m in the secondary sections, I’m offering (extensive) commentary. Timestamps are from the Twitter version.
AI and Economic Growth
They recorded this at the Progress Studies conference, and Tyler Cowen has a very strongly held view that AI won’t accelerate RGDP growth much that Dwarkesh clearly does not agree with, so Dwarkesh Patel’s main thrust is to try comparisons and arguments and intuition pumps to challenge Tyler. Tyler, as he always does, has a ready response to everything, whether or not it addresses the point of the question.
Cost Disease
The Lump of Intelligence Fallacy
The Efficient Market Hypothesis is False
Not Sending Your Best People
What would happen if we had more people? More of our best people? Got more out of our best people? Why doesn’t AI effectively do all of these things?
Energy as the Bottleneck
This is a plausible bottleneck, but that implies rather a lot of growth.
The Experts are Wrong But Trust Them Anyway
Tyler Cowen and I think very differently here.
AI as Additional Population
Dwarkesh tries to use this as an intuition pump. Tyler’s not having it.
Opposition to AI as the Bottleneck
China as Existence Proof for Rapid Growth
Second Derivatives
Talent and Leadership
We take a detour to other areas, I’ll offer brief highlights.
Adapting to the Age of AI
For something that is going to not cause that much growth, Tyler sees AI as a source for quite rapid change in other ways.
Identifying Alpha
Old Man Yells at Crowd
Tyler Cowen doubles down on dismissing AI optimism, and is done playing nice.
Some Statements for Everyone to Ponder
Trying to wrap one’s head around all of it at once is quite a challenge.
No Royal Road to Wisdom
Concluding Thoughts
For a while now I have found Tyler Cowen’s positions on AI very frustrating (see for example my coverage of the 3rd Cowen-Patel podcast), especially on questions of potential existential risk and expected economic growth, and what intelligence means and what it can do and is worth. This podcast did not address existential risks at all, so most of this post is about me trying (once again!) to explain why Tyler’s views on returns to intelligence and future economic growth don’t make sense to me, seeming well outside reasonable bounds.
I try to offer various arguments and intuition pumps, playing off of Dwarkesh’s attempts to do the same. It seems like there are very clear pathways, using Tyler’s own expectations and estimates, that on their own establish more growth than he expects, assuming AI is allowed to proceed at all.
I gave only quick coverage to the other half of the podcast, but don’t skip that other half. I found it very interesting, with a lot of new things to think about, but they aren’t areas where I feel as ready to go into detailed analysis, and was doing triage. In a world where we all had more time, I’d love to do dives into those areas too.
On that note, I’d also point everyone to Dwarkesh Patel’s other recent podcast, which was with physicist Adam Brown. It repeatedly blew my mind in the best of ways, and I’d love to be in a different branch where I had the time to dig into some of the statements here. Physics is so bizarre.
