asparagussomebody start listing downsides to this because i cant think of many
I just saw a mini-document on this not long ago actually. Spoiler alert, it's not as good as it sounds. Currently, it is not economically viable, nor ethically viable (in my opinion). Put simply, culturing muscle from stem cells to (replicate meat - no matter the meat) currently requires a liquid called fetal bovine serum. This keeps the cells alive while they grow into muscle and is necessary...
Fetal bovine serum is collected from the fetuses of dying cows. This requirement for this serum counteracts any current use for lab grown meat, as it requires roughly 50L of this stuff to make 1 burger. Just to put that in perspective, 1 cow yields 150-550 ml, so you'd need 90-333 cow fetuses to make a single burger. This is just the start of downsides, as other grown factors needed - for instance, TGF-B costs over $1,000,000/gram (about the price of a burger at your local resort)... you can check out this video if you want more information:

PS, not to poop on the post, just spreading some awareness.
