The other day I was discussing with a friend what would happen if there wasn't any need to work at jobs anymore, and whether people would be able to find fulfilment in their lives.
I think there would be so many new areas of knowledge being explored that we can't even imagine it. In my opinion, people don't find meaning, they create it, and they have an endless capacity for it.
I think covid was a good example of this. So many people took up a new hobby or tried something new.
Your optimism on humans is appreciated, although arguably not backed up by history: it seems to me like most places times and economic systems turn out a similar percentage of knowledge explorers: ask yourself what percentage of the landed gentry in the UK did this, for instance, and what percent just leisured away. I propose with no data the numbers are largely invariant; what a society or economic systems does change is the ability of the x% to make progress and impact/implement.
