Something I learned awhile ago is that most people that I consider "celebrities" really aren't that famous, and as such are generally pretty happy to respond to emails. In ~2014 I sent an email to Joe Armstrong (one of the creators of Erlang) asking some questions about concurrency because I still didn't fully understand why Erlang was supposed to be better for it. I expected him to just point me to an FAQ or simply…
I would love to read his reply, but of course I understand that correspondence is private. Do you know of something similar that is available on the web?
