I’ll start:

  • RSS and blogs, news vs. social media
  • XMPP vs. WhatsApp/FB messenger/Snapchat
  • IRC vs. Matrix, Teams, Discord etc.
  • Forums vs. Social media, Reddit, Lemmy(?)
  • Yeah. When a Chromebook can satisfy the needs of a lot of users, I feel some distros were ready even a decade ago.

    The installation step is a huge hurdle. I don’t know anyone, except techies, who has done it and even some techies haven’t. You can make it pretty (and some installers are both pretty and dead simple) but getting it on a thumb drive and booting from external media are just not user-friendly steps.
