I get your point about PDP-11's, but I'm not sure how it applies, practically. My family communicate with each other via XMPP, but I doubt they would be happy to use a PDP-11 for their daily computing :) My comment was not intended as an empty dismissal of all XMPP criticism. I'm happy to discuss and debate concrete criticisms of XMPP (contact info in my profile). But the parent post did not provide any such, only what sounds like a negative subjective experience whenever they last encountered XMPP. I don't think one person's opinion ought to decide if something should "die and stay dead", when there are so many projects and products built around it, and people using it daily to solve actual problems. XMPP has evolved massively over the past 20 years. Is it perfect? No (show me something that is!). Do we continue to improve it? Constantly.
