That's actually exactly my plan should my startup receive funding. I'd say of the first 30 people I'd hire, most are probably above the age of 30. Most have families. All are at the top of their fields. In the Bay Area, those factors probably translate to an average salary of at least $250k, which is roughly double what a typical startup pays in its early days.
I find it easier to do now than I did when I was younger, I see it as just what the job is. When I was younger, a sudden demand to do something different would have me annoyed because it was distracting me from what I really wanted to be working on.
Now I know that everything will be different in 5 or 10 years, so it doesn't really matter what I'm working on as it will be irrelevant soon.
My job requires a ton of rapid context switching, but I do find it much harder now than when I was younger (I am 46).
I'd prefer not to say.
>What does it do?
Put vaguely, delivers on the promise of future UI (think Iron Man), but does so solving some hard real-world problems in the process.
>Have you considered remote workers ...
Absolutely. While most already live in the Bay Area, there are several people from other countries. I'd have no problem with remote workers. There's definitely additional challenges involved, but nothing that can't be solved, especially with a mature team.
