Before biologists figured out how to "revive" pluripotency in adult stem cells - sometime in the 90's if memory serves - only embryonic stem cells could be use for research on stem cell therapy. And of course, if any therapy was to be discovered, only embryonic stem cells could be used for that also.
I remember back then, researchers were crying out that the potential of stem cell therapies was so great that it was worth harvesting embryos just to get the cell. That was obviously something of an ethical issue.
The pressure was huge to sidestep ethics and carry on with this wonderful new groundbreaking technology. Humanity couldn't pass up the opportunity to take advantage of this because of silly outdated ethical principles!
Well, the law stood firm, and it forced the researchers to fnd another way to get pluripotent stem cells from adult cells - something which is now commonplace: nobody harvests embryos anymore.
Same thing for AI: if it can't exist without stealing from everybody, then it shouldn't exist. Nobody should cave to the AI industry's demands, however much pressure they put on the legistlator. It will force AI professionals to resolve the theft problem and reinvent their industry to be compatible with common decency. Just like the stem cell industry did.
Caving to the AI industry's demands is the lazy way out of the problem, wouldn't foster innovation and would simply entrench theft.
