I think the widespread adoption of Linux is only going to happen from the bottom up. Corporations aren’t going to widely adopt Linux until Microsoft becomes a costly liability to them.
It will probably be the result of CoPilot. Will it be a huge data breach of bank or healthcare records? Will other governments flat-out refuse to run an OS with built-in spyware? Who knows? But it will be something awful that might even get our “mainstream media” to sit up and take notice.
You’re probably going to be installing and changing a lot of stuff over the next few weeks. Make sure you use TimeShift to make system snapshots. (It works like System Restore in Windows).
You can even restore a system that won’t boot anymore, by booting from a Live usb stick, running TimeShift and choosing a snapshot off your hard drive.
