How many engineering graduates end up being Sal Khan? Or writing something like PGP or Tor? He didn't say all engineering graduates should go into public service, he said that more of them should. It takes working from both sides to create a better world. Without reasonable people in government, Tesla would have been crushed before it ever got off the ground (without even talking about the subsidy buyers of its products can get). One good teacher is, perhaps, less valuable than Sal Khan. But we only need a handful of Sal Khans, at most. So one good teacher is more valuable than one more person trying to be another Sal Khan with basically zero chance of success. Am I saying that no one should try to be another Sal Khan? Nope. I'm just saying that most people won't, even if they try, so they should have a good backup plan, like becoming an awesome teacher. Really, it's the same type of advice people give to promising young athletes, shoot for the top, but have a plan to land on your feet if you miss. The hacker skillset is a big lever, but it isn't magical, and most people will never change the world in a big way. So if a few more engineering grads decided to go into public service instead of writing database apps or starting another mobile social network, I think the world would benefit.
