No amount of technology can solve the starvation in those countries. The starvation in those countries aside from physical blockades and wars like in Palestine if not usually due to lack of tech or agriculture. In any case, even if the land is bad, Israel itself is another example of crap land turned fertile by new technologies they were forced to invent during the course of the 40s and ahead by scientists like Bass. Here you want to block the biggest engine of technological and science development that has ever been invented.
The AI companies do what they must to market themselves, there is no reason to think it should be much different from other past mass disruptive technologies (today agriculture is down to just 2% of the population from 60-80% earlier for instance).
And if it solved most labor and jobs, then what? Would you rather block it than try to see how we can transition to a economic and government system that will actually let us enjoy it.
And I doubt we will ever run out of problems, there is always outer space as an endless source of new problems.
