For socialism to work requires that we become something other than human.
Automation and robots are "something other than human", however they are/will be able to do the most of work which humans had performed for millenniums.
Not intending to put words into Biomech's mouth but I guess he meant that we'd have to give up individuality i.e. become hive animals.
That is exactly what I'm saying.
There are *elements* of socialism that could be workable, in a voluntary society. But the whole picture? Only if we become something like the Borg. If that's the vision of the future that most people want, I'll be bowing out.
Luckily, it's not. They just want the freebies, and that eventually comes to a halt.
