I think it’s pretty fascinating. So far it’s pretty far from being marketable and I wouldn’t want to eat it (and probably won’t for a long time), but it has some interesting potential. The most interesting aspect in my opinion is how it requires a lot less energy than raising live animals. Animals “waste” a lot of energy moving around doing their animal things in addition to growing the meat we eat so we only get about 10% efficiency from the feed we give them. These cell cultures just sit there and spend all their energy growing so we get about twice as much efficiency out of them. This has tremendous implications for our ability to switch to an economically viable meat-based diet on a large scale.
There’s a lot of issues with this still, and I’m not thinking about the product itself which at the moment isn’t really viable, but in any case that’s an engineering issue and thus should be left to the bio-engineers for the time being. The issue I’m most worried about is even though this reduces the energy requirements to grow meat it still doesn’t enable sustainable agriculture by itself. In fact it might prolong the life of our current industrialized agriculture model, possibly leading to greater ecological damage than if we continue at our current pace and realize something needs to change sooner.
