Of course, it will never be enough. The goalposts will move until we run out of them.
The reason we won't let AI run rampant is because it's anti-human. Even if AI can do everything, why would we allow it to? We don't have to do that, that's very much a choice.
We're at the point where we have humans advocating not only against other humans, but against themselves. If people are going to be out here arguing for self-destruction on the order of suicide, they might as well save us all the trouble and put a gun in their mouths. At least that way, humanity might have a few less pathetic losers who put computer programs before themselves.
Maybe that's harsh, but that's how I see it.
I have seen enough human incompetence that AI incompetence is beginning to look quite favorable. AI performance, at least, goes up generation to generation. If you've ever faced minimum wage workers, you know that they are, at best, consistently the same level of awful.
But if we move us faster than the goalposts, we can outrun them.
