Though I was a tiny contributor to Sendmail long ago, I approach my 61st birthday and realize that I had no large part in constructing the Internet of today. But I have enjoyed it immensely and kept it running for awhile as an admin. I could bore everyone with criticism, but last year I just wrote a fiction book instead and recently made it free forever to listen ( https://www.youtube.com/watch?v=mtxgpaXp9vA ) or download/listen ( https://archive.org/details/stargazer-steven-pitzl ) because I don't wish to navigate the self-publishing world, it would be nice to get feedback some day.
