> I've never heard of a tech genius who also cared much about the qualities you mention.
How about von Neumann, famous for always being in an impeccably tailored suit? I hope he's genius enough for you.
You don't even have to go past the very first hackers to find ones that care about those qualities. There are many, many other examples.

> Von Neumann took great care over his clothing, and would always wear formal suits, once riding down the Grand Canyon astride a mule in a three-piece pin-stripe. Mathematician David Hilbert is reported to have asked at von Neumann's 1926 doctoral exam: "Pray, who is the candidate's tailor?" as he had never seen such beautiful evening clothes.
