I’m willing to grant you your step 1 (AI becomes capable of automating almost all mental labor within 3 years).

I think your step 2 (“Shortly after, say in 1 to 2 years, AI becomes capable of automating almost all physical labor”), is HIGHLY implausible, but I’ll concede not impossible.

But your step 3 (“The full automation of most economic activity allows rapid economic growth, with total economic output doubling times likely in the range of 1 to 3 years.”)

Doubling an economy as enormous as ours (even limiting it just to the U.S.) is an ENORMOUS lift.

Especially in the context - with which I totally agree as highly probable - of no AGI and a human consumer world.

Tyler Cowen thinks it’ll be tough to get even a 0.5% annual productivity gain from where we are now. You are positing at minimum a more than 20% annual gain. Given that you’re positing most humans will fairly quickly stop working, but humans will still be necessary, this is effectively an even more massive boost to human productivity you’re positing.

Could there be some examples of this, even many, in your timeframe? Sure. But to do for all workers and companies on average?

Even if you are right about your step 2, it will take many years to be able to actually build and deploy all the robots you’re describing merely to replace all the human labor in the U.S. you’re asserting, let alone the entire world.

Even ignoring the likely political pushback virtually guaranteed to occur, I don’t think it would be possible.

As Bryan Caplan says, I’d be delighted to Bet on It:

i.e. in the absence of AGI, we will not deliver a doubling of real U.S. GDP per capita (humans) over any 3 year period in the next 10 years, let alone a doubling in aggregate world GDP in a 3 year span.

Now I do find your post interesting and thought provoking. But the odds of your step 2 seem low to me (though I’m willing to concede you might be more expert on that point than I), and the odds of your step 3 are surely miniscule.

Even if you are 100% correct in your forecast about the technological capabilities.

I will close by stating this is one bet I would be absolutely *delighted* to lose!
