These people probably smartest developers in the world. I wouldn't compare myself with them.
You think? These devs are some of the devs in Israel. The best get too popular to work in secret labs like NSO. I find it hard to believe that the best devs are secret ones in Israel. But obviously, I could be wrong.
I'd imagine there is a fair share of amazing developers that have no interest in flaunting or broadcasting their talent, for at some level it just isn't necessary to advance their career.
It does not give me imposter syndrome. It just tells me I know absolutely nothing despite having a so-called advanced degree from "a top school". God damn it.
