The following framework explains why horses suffered complete replacement by more advanced technology and why humans are unlikely to face the same fate due to artificial intelligence.
Humans and AIs Arenât Perfect Substitutes but Horses and Engines Were
Technological Growth and Capital Accumulation Will Raise Human Labor Productivity; Horses Canât Use Technology or Capital
Humans Own AIs and Will Spend the Productivity Gains on Goods and Services that Humans Can Produce
Comparative advantage means Iâm guaranteed work but not that that work will provide enough for me to eat
I agree. The last section of the post above briefly discusses this.
The argument is plausible and supported by history but itâs not a mathematical deduction. The key elements are relative productivity differences, technological improvements that increase labor productivity, and increased income generating demand for goods and services produced by humans.

Higher wages are not always and everywhere guaranteed, but humans are not likely to face the same fate as horses. We are far from perfect substitutes for AIs which means we can specialize and trade with them, raising our productivity as the AI labor force multiplies. We can take advantage of technological growth and capital accumulation to raise our productivity further. Weâll continue inventing new ways to profitably integrate with automated production processes as we have in the past. And we control the abundant wealth that AI automation will create and will funnel it into human pursuits.
Thanks Vasco, I hadnât seen that. Do you know if anyone has addressed Nathanâs âComparative advantage means Iâm guaranteed work but not that that work will provide enough for me to eatâ point? (Apart from Maxwell, who I guess concedes the point?)
I think MaxWell conceded Nathanâs point, and I do not know about anyone disputing it in a mathematical sense (for all possible parameters of economic models). However, in practice, what matters is how automation will plausibly affect wages, and human welfare more broadly.
+1 to this being an important question to ask.
Hi Nathan and Ben.
I liked Maxwellâs follow-up post What About The Horses?.
I agree. The last section of the post above briefly discusses this.
Also on comparative advantage, I liked Noah Smithâs post Plentiful, high-paying jobs in the age of AI.

And letâs not gloss over this, right. His concession is a knockdown argument to the overall thesis.
If AI means I canât eat, but can still work, I cannot eat. Game over is much more likely.
I do not think the concession matters much. I ultimately care about expected changes in welfare, not whether something is possible.
