We, humans, decide what we can and cannot eat. And some of us still hunt animals just for sport or for their horns and fur, even if they are in that "higher intelligence" bracket.
But hopefully as our societies evolve, and technologies also evolve to at least give us a choice between having to eat a chicken, and having to eat manufactured/replicated meat, we'll learn to give up on these, too.
I see it as inevitable that artificial meat replaces wholesale slaughter with actual animal rights. Let's just admit that most of the world (myself included) won't stop eating meat until that artificial stuff is here and focus on the easier topics first.
You wouldn't be able to manipulate a dog into taking its own life, but with this cockroach you would against its will.
The people behind this project say that it is for educational purposes, but really now.. how many people will use it that way?
