I disagree. If you could run a machine that performed equally well in a real-world environment as a human, at a lower cost than it costs to feed and pay a human laborer, it would be a no-brainer to invest in thousands of these machines to perform various consulting services that are bought and sold over the internet. And here I've only touched the slice of the world economy that exclusively consists of information-inputs being turned into information-outputs.

The market for general AI is massive. The only reason you can't see it is that no similar service exists. So this is not an argument.

(In fact, a similar service does exist: Indian IT outsourcing sweatshops, which while usually not delivering top-quality products still are massively profitable).
