You say the world doesn't reward the doers but CTOs and a few key Apple engineers were/are rewarded with heavy bags of money. They don't get the media features because the company has to pay the media to feature Steve Jobs telling us he's just a cool hippie, actually, and not a ruthless psychopath. Doing the same for the CTO serves no marketing purpose for Apple.

As for Nikola Tesla, he spent a lot of his money on things that didn't work out, like the unfinished Wardenclyffe Tower.

None of the examples you shared is the world not "rewarding" them compared to people who are not those things.
