Assume the existence of a large scale Star Trek Replicator that can almost instantly create anything.
There are only two possibilities that result:
1) We now live in a post-scarcity society where everyone self-actualizes and no one wants for anything.
2) We now live in a society where the small % of the population that owns the Replicators self-actualizes and wants for nothing while the remaining 99.9% of the population can f** off and die.
While we can get to a post scarcity society where people can live for free without a job, there are still going to be economies around "liberal arts". You cant realistically say "hey replicator, give me a usb filled with music that I like". You would have to find out which music you like, and random search on this is not really enjoyable, which would then means that there is economic opportunity for discovery, e.t.c.
Sounds like we arrive at point #1 in any case, there's just a question if a mass genocide happens in between. Probably depends on how gradual the transition ends up being.
