We only sequenced the first cow genome 15 years ago and plenty of plants and fungi produce high quality protein/fat/etc - it's not like we're starting from scratch the whole point of bioengineering is that we can cheat using stuff nature figured out for us. It's certainly not scientifically impossible. In the zero interest rate hype cycle over the past couple years plenty of startups convinced themselves that they could totally make it work with cell culture and stupid expensive bioreactors and media and stuff since that was the only tech that was 'ready' even though at best all you can get is an overpriced lean meat only replacement for ground beef, and this article seems to take for given that this approach === meatless meat. I think it's useful to keep the questions of 'are these tech bros going to figure out how to make producing meat in class 8 cleanrooms viable' and 'are bioengineered animal-free meat replacements going to happen in the next few decades' seperate
