The level of greed, hubris and stupidity of some people never ceases to amaze me.
Levandowski was paid a bonus of $120 million while at Google, which is more money than any reasonable person will need for several lifetimes. This was actually a running joke at Google (while I was still there) to describe $120M as "1 Levadownski". Like Sundar one year was described as earning "only 1.7 Levadownskis" (he got paid $200M one year).
Why someone would risk jail time doing something so clearly wrong (taking material trade secrets from an employer) for even more money is just staggering to me. Even if he escapes prison time the stress and cost of a protracted criminal trial is huge. The loss of reputation is likely permanent.
I get why some high fliers have big egos and they privatize their success (even when pure dumb luck can be a huge factor). This is the hubris part. Right or wrong, that belief in your own abilities is almost a prerequisite for disruption.
The interesting part is how he "cheats". Like he clearly went to efforts to cover his tracks. Those aren't the actions of someone who felt they didn't do something questionable. So at this point, it's not about the hubris of the individual, it's about being perceived as being gifted, intelligent, a visionary and so on.
Honestly it makes me glad when such charlatan have their almost inevitable fall from grace.
