I'm also weirded out. Who wants to work? How can you not have as a life goal to not work? It sucks for the most part!
As for Marx and Keynes and others, thinking about what people will do if they're freed of labour, have you SEEN youtube? People are not lacking ideas on things to do, quite the opposite!
My work is my life's dream. I did it for years as a hobby making no $ (losing money really) and worked terrible tech jobs I hated until I could switch the two.
Now I work 80 hours per week but it feels like 5. So it's not work to me.
