I think the idea of lab-grown meat in the OP is supposed to be a much better simulation (I mean, arguably not a simulation at all) than impossible/beyond, and be able to simulate whole pieces like a steak or piece of chicken not just ground meat.
But yeah, that's a question I have, with plant-based meat like beyond/impossible already being way better than I would have predicted a few years ago... what's the point of spending so much money on the "moon shot" of vat-grown meat, instead of just doing more with the plant-based approach that's already working well?
