I am also in my (late) 30s. I would definitely question myself if I were “constantly the person with the most technical skills in the room”. I of course think I’m smart, but I am rarely surrounded by people that I think I’m smarter than…

I agree work is just a means to an end of not starving, but I like learning and growing enough that if that were the case (most technical among my peers), I would start looking for another opportunity.
