Wirh every potential productivity revolution it's the same. it will make poeple's job obsolete, it will make everything so much faster and cheaper that people will just "work" for the pleasure of it.

After a while it also ends up being the same, the job market is shaken and people now have to work just as much as they can but in different, newer jobs to make different newer things.

No post-scarcity commie utopia is ever going to be possible because even in that society, the people that work their ass off will be so ever slightly ahead of the others, so now everyone hast to do it to not be "left behind".
