Heh, back in the early 2000s when I was busy reading up on computer history I was very surprised that a lot of Internet standard pioneers and computer science giants were still alive. Like, people from the stone age. This is such a young field.
I seriously thought John McCarthy (creator of Lisp programming language) had reached such a status of existence that he would probably never die. (sadly, he did.)
Despite him not posting, I visit his Mastodon profile from time to time. It has such a cute sea turtle banner. Glad to see that despite him being a kernel developer titan, he still spares a thought for the humble shell programmers too.
