A valid point. Especially as self driving is nowhere close to bringing in revenue for any of the companies involved. Other than engineers working with batteries or metals which lead to actual billion dollar revenues.
You might say what's unusual with Levandowski is that he made so much money while working for someone else; and while not actually achieving any additional revenue.
If a battery or metals (or self-driving) engineer comes up with a material break through and starts a company they could easily eclipse Levandowski's earnings.
