Exactly bro! Now keep on rocking in the free world and understand that hubris alone does not a good programmer make but a good programmer is hubristic. Therefore hubris is a poor heuristic no matter what any tech bro tells you.
Therefore you should at least make an effort to dress up for an interview because you never know if it's your last chance to make any sort of impression.
And let your hubris shine that way instead of choosing the casual path that every other one will certainly choose.
Edit: of course this argument is lost on all the beautiful minds who spare no effort at shabby chic
Relevant quote: "As soon as the guy walked into the room, I knew it was going to be problematic, because he seemed extremely straight-laced and uptight, dressing more like an insurance salesman than a technologist."
Jobs was an ass, but Andy had a point: dressing correctly depends on the context. The idea of dressing "up" or "down" as if it was a single axis was never correct, and is even less nowadays.
Therefore you should at least make an effort to dress up for an interview because you never know if it's your last chance to make any sort of impression.
