I'm really hoping that the Linux gaming folks keep making progress on Windows-on-Linux compatibility so that I can transparently and with zero-fussing run any arbitrary Windows application. Unfortunately there's still plenty of professional software that has not been and will never be released for Linux.
Linux ages like WINE, Windows ages like milk.
The incentives for improving Linux are driven only in part by commercial interests, and those interests are not completely centralized. Windows' fate is entirely in the hands of the current Microsoft leadership, and they seem hellbent on extracting maximum value from their users while ignoring the suffering their "Continuous Innovation" creates.
It's almost as if they want everyone to start looking for the exits, and thankfully Linux is finally at the point in its maturity on desktop to start attracting power users who have no prior experience.
I don't think 2026 is the year of the Linux desktop, but it does feel like we're at the start of a big shake-up in the industry. Once we start seeing the hockey stick pattern in the adoption rates I would expect that more money and developer time will follow to help smooth out the areas where the transition is still difficult, like professional software.
