I do love the joke, but it is worth remembering as well that all of those S were to a certain extent afterthoughts to fix otherwise insecure protocols.

Given how old FTP and HTTP are it's fairly understandable that they weren't initially designed with security in mind, but I think it's valid to question why we're still designing insecure systems in 2025.

Totally agree, If we have made a mistakes in past we must have learnt from it and when designing a standard specially with AI where the outcome is non deterministic we got be more careful.

That's quite the point of the joke. Even today, we still design things that will need an S tacked onto it at some point in the future.
