So you're fine with cloning consciousness as long as it initially runs sufficiently glitchy?
That's my point exactly: I don't see what makes clones any more or less deserving of ethical consideration than any other sentient beings brought into existence consciously.
That is a reasonable argument for why it's not the same. But it is no argument at all for why being brought into existence without one's consent is a violation of bodily autonomy, let alone a particularly bad one - especially given that the copy would, at the moment its existence begin, identical to the original, who just gave consent.
If anything, it is very, very obviously a much smaller violation of consent then conceiving a child.
Sure, there are astronomical ethical risks and we might be better off not doing it, but I think your arguments are losing that nuance, and I think it's important to discuss the matter accurately.
This may surprise you but EVERYONE is brought into existence without consent. At least the pre-copy state of the copy agreed to be copied.
A simulated human is entirely at the mercy of the simulator; it is essentially a slave. As a society, we have decided that slavery is illegal for real humans; what would distinguish simulated humans from that?
