So the problem isn't robots, it's the structure of how we humans rely on jobs for income. I don't necessarily feel like it's the AI company's problem to fix either.
This is what government is for, and not to stifle innovation by banning AI but by preparing society to move forward.
Since there already was enough food, the market is saturated, so it would effectively reduce the price of all food. This would change the ratio so that the farmer who grows more gets more money in total, and every other farmer gets a bit less.
As long as there is any sort of growth involved - more people, more appetite, whatever, it would be value creation. But without growth, it's not.
At least not in the economical sense. Saving resources and effort that goes into producing things is great for society, on paper. But with the economic system that got us this far, we have no real mechanism for distributing the gains. So we get over supplying producers fighting over limited demand.
The world is several orders of magnitude more complex than that example, of course. But that's the basic idea.
That said, I'm not exactly an economist, and considering it's a bleak opinion to hold, I'd like to learn something based on which I could change it.
About the farmer needing to change jobs, in the interview that is the subject of this thread Ilya Sutskever speaks with wonder about humans' ability to generalize their intelligence across different domains with very little training. Cheaper food prices could mean people eat out or order-in more and then some ex-farmers might enter restaurant or food preparation businesses. People would still be getting wealthier, even without the tailwind of a growing population.
