I first encountered Joe in this video - a wonderfully funny account of modern computing (from 2014)
I was glad to read this. I love Joe Armstrong's work-- the book, the language are both great. (Especially the book. It just reads well.)
To read that Joe failed, then came back to such success is inspiring. In my mind, Joe Armstrong has had a fantastic career, and leaves with only positive impressions. We should all be so lucky!
Rest in peace, Joe. I was just getting to know your work, but thanks for doing it.
It makes me happy that someone I respect enormously managed to do something like this. Also, Joe's PhD thesis is a genuinely great piece of writing, highly recommended if you haven't read it.
