I definitely wouldn’t predict that Linux is taking over the world or anything but it wasn’t that long ago that playing AAA games on Linux on day one of release was ludicrous. Now the most popular PC handheld runs Linux, a PC console launched that runs Linux.
Now we have hardware like the MacBook Neo that threatens Windows even more. Sure, the XPS 13 came out and is arguably a compelling alternative. But I think the mindshare damage has been done on that one.
The idea that Windows might disappear entirely is not that far-fetched, especially when you look at Microsoft’s financial results.
If I was a PC OEM like Dell I would probably band together with other OEMs like Lenovo to make my own Linux distribution and support Windows offboarding even further as a hedge to my business.
IMHO the big difference is in enterprise Vs personal Windows, enterprise Windows can genuinely be a very lean, fast experience that is great for work. But my personal PC running windows is very firmly in the "I wonder what the latest update will break" teritorry.
