The point is, this isn’t “fake meat”. It’s not made of fungus, or grain, or soybeans. It’s muscle tissue. It’s just not grown in a complete animal. Frankly, I’m much more interested in the idea of growing human organs from a patient’s own stem cells, as a non-rejecting transplant.
And also look on the bright side - no mad cow disease, worms, bacterial and viral infections originating from a cow being in the wild. Better controlled growing conditions to keep the meat disease-free, with the right amount of proteins and nutrients.
