How did an office sub-leasing company (Wework) become a tech company that was supposed to change they way we live and work and create the first trillionaire, or whatever craziness they cooked up?

From what I've seen, you find a charismatic dude with a good story that they probably even believe themselves, and another dude with a lot of money who wants to make that into even more money and you get them together. Then you find more believers.

It's more akin to religion than anything else, but employment seems like the new religion for many - it's certainly an integral part of identity.
