Yeah, clear example of survivorship bias... not to sound negative, but if Facebook had become nothing, odds are Boz would be nothing more than another engineer. It's all too common a tale to hear people spout their nonsense and think they got to where they are because of some inherent talent or skill, but at the end of the day, getting to somewhere like Boz these days is just luck. Does anyone really think you could start as an L4 at something like Amazon these days and end up as a CTO? Nope.
