Oh, they're cashing in right now. Look for them to exit in 6-12 months with millions.

Carmack does not seem like the type to be "cashing in" unless he felt that the engineering work were no longer compelling and interesting. It sounds like he still feels it's interesting work, so I don't think he's being driven by money.

Carmack has FU money twice over. This is about seeing his dreams made into reality.
