I think they should not call it meat anything. They should just create a new thing, so people can appreciate it for what it is, rather than expect meat and get an uncanny valley effect.
It’s called meat because it tastes and feels like meat. It’s a perfectly cromulent word to use because it describes what the product is.
Soy beans don't have nipples.
Once the difference between real meat and artificial meat is closed in terms of flavor and texture (to the point where most meat eaters will not have a huge preference) then the framing being taken now will pay dividends.
But, do all these anti-meat people not care about all the cows and chickens that got to exist because people love eating their tasty flesh?
