There was a interesting discussion somewhere (can't remember where) that called communism the first techno religion. The idea was that everything is build around the expectation that labor will become less important and owning means of production becomes paramount because of automation. Very relevant thoughts nowadays. Nice to look in the mirror of the past.

I highly recommend Eric Hoffer's The True Believer if you're interested this topic at all. It's a short book full of major ideas.

Hoffer's treatment of the phenomenon is just as fresh and relevant today as it was when he wrote the book in the 1950s.

I got downvoted for suggesting that Maoism was a religion, but it quite clearly had more commonalities than differences with the more extremist religious cults (as did Stalinism, Nazism, etc.)
