There’s the question of what sort of feedstocks they’re using and where they come from.

I would assume that it’s something like what the animals they’re replacing eat, but presumably in smaller quantities since they’re only growing muscle tissue and not an entire animal.

There’s something to be said for a device that transports itself around marginally-arable land eating grass and pumping out fertilizer while creating edible protein. Especially if the alternative is intensively-farmed row crops like corn and soy that tend to require tons of fertilizer and herbicides.

IMO an equally exciting area of research is taking something like algae that only need water, sunlight, and some minerals to produce food. Which could then be further processed into lab-grown meat or be eaten as is.
