Doesn’t lab grown meat need a lot of growth serum, which is currently extracted from pregnant animals? So as it stands it is not a solution to help reduce climate change (nor animal suffering). For that we’d need a more sustainable way of producing these serums. I’m not aware of any methods which are proven to work at scale.

5 years ago it took ~50L of fetal bovine serum (FBS) to grow a burger, at around USD 400/L. FBS is made from the blood of unborn calves, which are taken from slaughtered cows.
All lab meat companies are obviously looking to reduce that input cost by finding a replacement.
Beats me! I don't expect it to be more efficient today, it's brand new tech. My hope is that it will be much more efficient as research continues & economies of scale start to kick in. It may well turn out to be a dead end, but until that's clear, I think it is exciting to think about.
