There are some quite remarkable threaded conversations that have been archived by various agencies and libraries; you're correct that Musk now owns Twitter, and a weak comparison but the only easy one is that if Zuckerberg was so singularly and personally involved with running Facebook, it would be a different space altogether. Or gone. He has boards and groups who do things there. Musk appears to not be trying to understand the mechanics of Twitter before disassembling it.

Looking at my account and making a list of who I'm following so I can look them up elsewhere is something I need to do. I haven't Tweeted anything noteworthy that I need to archive in my own account.
