So I understand this is not realistic currently; However where I currently reside, basically everybody grows their own food, and has plenty of time to be doing other things in the meantime.

So while we all need robots, there are probably a hell of a lot of people who would be able to produce even one crop a year in their backyard, who don't bother.

No reason the robots won't reach "other ways" at a point either. I think it will take a lot of combinations of solutions over time.

I still think there should be a lot more rotation between general crops, animal grazing and replenishment cycles. "Live" soil is becoming a problem and we keep extracting/killing it faster than it's getting replenished. Not to mention all the pesticide issues.

We would probably all be much healthier if instead of indirectly subsidizing make-work desk jobs, organic vegetable gardening was subsidized instead.

That would be bad. We would require much more area for the same output.

Gardening would have a higher yield per area than farming. The amount of area needed would decrease. Labor needed would increase.

Not really. Gardening the typical garden crops do - but those are high labor which is why we garden them. You could plant wheat in your garden it would be more labor, but your yields would probably be less, or if you are really good the same.

Most people would be much healthier consuming less soybeans and corn syrup and more garden vegetables.

Actually we would be better consuming more soybeans. Most of it goes to animal feed.
