"Meat", at best. Yes, muscle cells in a matrix. The problem will be getting the rest of the structure to be there, and to grow properly, such as connective tissues and fats, and to get the same amounts of minerals and other nutrients into the "meat" as an animal does. Meat, as a food, is much more than a clump of muscle cells. Then there are the costs to do this properly (packaging the correct nutrients in bioavailable forms, for one), which will likely be much greater than simply letting a cow loose in a pasture to do what it does. This is to say nothing of the long-term testing that should be done on any such product — whether it promotes cancer, leads to misfolded proteins, thereby jetting new and interesting prions into the population, etc. The 20th century was marked by morally-unmoored technocrats allowed to run wild; why is the 21st century doubling down on this?

I think most are raised on feed farms; I think antibiotics and hormones play a role in at least some, but perhaps most? They also emit C02 which we'll eventually have to pay for. And more generally animal farming is a (the?) primary source of new diseases already. I wouldn't expect "lab" grown meat to do any worse there, but perhaps better. Still, it is something new and new always carries some risk. But > The 20th century was marked by morally-unmoored technocrats allowed to run wild; why is the 21st century doubling down on this? It was also marked by dramatic increases in quality and quantity of life.

  > Are most cows pasture raised? I think most are raised on feed farms. This is very much dependant on the country. For example, New Zealand beef is about 96% pasture fed, Australia is about 66% pasture fed, and Brazil seems to be about 90% pasture fed.
