I respect any hacker who gave up playing the game years ago because they realized just how insecure everything was, yet became comfortable with this (Read 'everything is broken' by Quinn Norton, and watch some of Haroon Meer's talks).

It's a kind of comfort that comes with years of hacking, and the quality of their work is unmistakeable. Look at Vinay Gupta's work on Ethereum. He openly states how much he distrusts Intel and X86 and is doing public speaking to wake others up about this. Also any person working on open hardware, or Trusted platform modules are worth watching.
