To get VC money one must be an arrogant bullshitter so it is interesting to compare the 'careers' of Elizabeth Holmes vs Adam Neumann since the latter ended up with a personal fortune > $1 billion and the former in jail.

As you say Holmes made the mistake of devising a formally checkable business idea whereas Neumann's ideas were always vague bullshit.

Saying she also had a working device was, well, fraud.

The lesson for those who want to follow in Neumann's footsteps is to make up a vague unverifiable set of bullshit, then the Ponzi scheme can be kept going as long as possible, enabling you to siphon of some cash into your pocket.

Since VCs are basically looking to get in early on a Ponzi scheme the facts don't matter to them.
