Stonebreaker is 80 years old and he makes a new company. I'm almost 50 and wondering when my tech career will end. I would be happy if I could start a new company at 80.
You don’t need to stop, especially if you have money and enjoy it. I will die starting new (tech) companies; I don’t need to make money and I just don’t like other things.
There's some saying about being old vs feeling old. Can't remember the wording.
