We already do eat vat-grown stuff. And I'm mostly talking about staples, which make up the vast majority of farmland. For anything mashed or made into flour or oil or powder, there's basically no fundamental difference between it being made in a vat versus a field. Whole, unprocessed vegetables like lettuce, etc? Well, that corresponds to a small fraction of farmland, and it also grows great hydroponically. Don't need to grow that in vats.

>>> it also grows great hydroponically

you must be joking. A lettuce which has grown in some backyards, with time and sun (and a lot of fight against various insects, true) tastes so much better.

But maybe your hydroponics are better than mine.

I'm all for optimizing farming if it's possible but I don't want any compromise on quality (taste, nutrients, whatever).
