You're the Sensei's guy? Thanks! I remember reading articles here when I was learning Go as a teenager 20 years ago.
Do you already have a plan in place for what should happen to it after those 25+ years (universe willing)? Anyone to inherit it?
My experience is that it's very unlikely to find someone to carry such a site forward for decades -- everyone I met (except for 1 guy) loses interest after a few years.
Don't know if archive.org would carry a read-only version forward.
Wow, thank you for all of your work on Sensei's Library! It made a huge impression on me in ~2003, and has really helped me understand Go better and get stronger.
I work on Let's Encrypt. I'm glad you find the service useful!
This project really told me how important it is to leave comments for your future self - especially, if your future self hasn't touched some parts of the code for 15 years :o)
Anyway, I'm approaching 50 now, so I assume that Sensei's will be here for at least another 25 years.
