Replacing all jobs won’t create true abundance because the resources required to create things are finite, namely land and space in general

We'll have solved these problems though, space wise whether it be by reducing ones footprint down to practically nothing, with nanobots ensuring our bodies get fully taken care of or through expansion to other planets

Resource wise we'll simply be using fully renewable resources, we're talking end game here, all jobs are being done by computers, there is nothing left for us to do but have fun or babies? I duno what we'd do if all jobs were fully completed and there was literally no work left

It's also difficult to say how these problems will be solved without coming across like "it's the future!"
