What is the smartest person you know working on?

Raising her children

I've never thought about who I know that's the smartest before.... it's either my friend who works on firmware for cable modem head end stuff, who used to be a volunteer fireman in his free time, along with raising a family

Or... the other friend who used to do everything, EE, MD, Aviation mechanic, instructor, pilot, avionics repair, computers, law enforcement, but is now in declining health, and I help him fix old radio gear, test equipment, cesium beam atomic clocks, etc.

I don't have a big circle, but in general the smartest people didn't seem be fixated on work and coding outside their 8 hours of work. Maybe that makes them more creative and better problem solvers in the end?

A lot of things but not really much at the same time
