It will be animal cells differentiated into muscle tissues on collagen scaffolds initially. The technology comes from attempts to grow functional organs (ie, liver) that are biocompatible in the body serum proper. If there aren't health effects from transplantation within the animal type you can probably eat the animal tissues just fine. It's the same thing. It's meat. It's just without the animal suffering. And hope…
For context, the life of an average herbivore in the wild consists of living with no shelter in harsh weather while having to fear every sound. And it typically ends by being ripped to pieces by a predator and eaten alive while the brain still has some residual oxygen and awareness. The typical farmed animal experience where you are sheltered, vaccinated against common illnesses, provided food and slaughtered after b…
I think that's hard to say. But I also think "the alternative" to farmed life is somewhat ignored by vegans/peta activists.
On the one hand, as you say, death is more painful by the claws/teeth of a predator; that is certain. But life itself with little shelter (but usualy some) is the natural state of afairs for most mammals. To say that that is suffering is to say that life itself is suffering, which I think is counterintuitive as suffering is evolutionarily a means of preasuring an animal to escape from the suffering. Not to say that isn't possible. It's hard to say if the natural resiliance (assuming it exists) that mammals have to little shelter and food carries over to say being croweded into small enclosures.
If anyone has any (scientific) articles on this topic I would be interested.
