"We need to keep building this stuff" Yeah, we really don't. As in there is literally no possible upside for society at large to continuing down this path.

Well if we eliminate greed and capitalism then maybe at some point we can reach a Star Trek utopia where nobody has to work because we eliminate scarcity.

... Either that or the wealthy just hoard their money-printers and reject the laborers because they no longer need us to make money so society gets split into 99% living in feudal squalor and 1% living as Gods. Like in Jupiter Ascending. Man what a shit movie that was.

We basically eliminated scarcity a few generations ago and yet here we are.
