as long as its significantly cheaper (than slaughtered animal), fills the stomach,
vat-grown meat will take off.

probably won't pass off as kfc drumstick, but expect this in your sausage and burger patties when it passes FDA

moot, cloned human will probably have rights too, assuming they're fully functional/conscious, like identical twin maybe
it'll also probably be cheaper, faster(less documentation) to get through black market,
or through cell-stripping and scaffolding

on the other hand, cloned human meat for consumption...
