Musk is so useful to Thiel because his antic goofiness helps cloak the true focus and viciousness of their agenda.
Addendum: I’m getting a lot of “Musk and Thiel are just greedy narcissists” responses. Sure. But there is also a clear political valence to what they do. They are part of an anti-democratic political project. De-contextualizing and de-politicizing that underestimates the threat.
