I'm pretty sure it's not impossible, but rather just improbable, because of how human nature works. In other words, we are not incentivized to do that, and that is why we don't do that, and even when we did, it always fell apart.

You are very right that AI will not change this. As neither did any other productivity improvement in the past (directly).

It's impossible, and not just because of human nature. Even if humans were more cooperative or altruistic, it's impossible to plan for disruptive innovations.
