I'm not saying it isn't possible to grow meat in a dish, I'm saying it's a terrible idea. It's not a question of "good enough", and meat is not just "cells, muscle, and fat". To use the example of grain-fed beef vs. grass-fed beef; grain-fed beef lacks essential vitamins and fatty acids. I won't even bother to put a link in here, just put "grass-fed vs. grain fed" into a search engine. The problem isn't that imitation products don't taste like the food they're supposedly replacing, it's that imitation foods like margarine are actively bad for your health. The point I'm trying to make is that the harder we have tried to industrialize food production, the more unhealthy everyone has become.
