I wouldn't eat it myself because I am perfectly happy and healthy on a vegan diet & know there is no need to eat meat.
I think it would be a big step up from people farming live animals, I just don't know how comfortable people would be with eating a science experiment...
I would be perfectly comfortable with other people eating it, although I imagine there would still be negative health implications... but at least the person choosing to eat it would only be impacting their own health, not the lives other sentient beings.
One downside is that making this IV meat would perpetuate the falacy that meat is necessary for a healthy human diet, and continue to normalise our consumption of it.
I saw this the other day. It sounds great to me, but I'm a bit skeptical of Bill Gates' motives, given his support of GMOs and his financial investment in Monsanto (the devil.)
