a huge gig economy is very likely
But is that really a solution?
No, the real solution is to automate every job and allow citizens to do whatever they want. Yet there will always be certain limitations and a direction we want to forge ahead.
For example, if there are infinite abundant resources how do we stop massive overpopulation? Innovative governance solutions will push the herd in the direction it needs to go with positive reinforcement for "right-action" and micro-charges for "wrong-action". It's a numbers game. Only a certain percentage of people need to do what they are told for massive societal gains.
I don't think resource availability has anything to do with population growth in humans. We've tried to make nature our slave and fooled ourselves that it's worked while really we've just been shitting in our own kitchen/living room/(maybe faces? I want something else here...)
My understanding is that statistically the more rights and access to education that is afforded to people with ovaries the slower the population grows. places that have better access to resources tend to have 0 or negative net population growth if immigration is factored out because they tend to be the same places where women have more rights and are allowed to go to school. which also means poverty and population rates grow together.
