I get what you're saying, but it's an "all food will be cooked by machines"* argument; yes there are robochefs which can produce doughnuts, noodles, pizzas, etc; but there's an ever-expanding area of innovation and niche-filling that humans are really good at. Ask any Michelin-starred chef, or freelance software engineer.

Software engineering is not a zero-sum game where the AIs rise to the exclusion of humans - it's an expanding space.

*and then there's the meta: does using an oven qualify as cooked-by-machine?
