First-class support for Windows applications might just become doable, if Wine continues to progress and Win32 doesn't accelerate. There were a handful of quality of life improvements in previous Windows releases, but the biggest Win32 changes feel like they happened quite a while ago by now, and for good reason: Win32 is stable and mature. It's still a moving target, but not by nearly as much, and even if Microsoft wanted to move it for the sake of moving it, they might find more resistance than they can completely overcome. For now, I think Wine is still not good enough to recommend people just use for everything, though. It's incredible, but incredible doesn't make Photoshop install.
However, I also think that we could "solve" a lot of the compatibility problems.
There are tons of old Linux binaries that don't work anymore. But... They could. A lot of old binaries, surely the vast majority, could absolutely run on a modern kernel. The problem is the userspace. The binaries themselves contain oodles of information that could be used to figure out what they need to run, it's just that there's nothing in place to try to make sure that stuff is available.
I really believe we could make it possible for a distro, out of the box, to make old binaries "just work", double-click and run. Want to install an old game from an .rpm or .deb you have? The system could identify what base OS that is and install it into it's own chroot with its dependencies, then create desktop icons for it. Execution failures? Missing libraries? Xlib errors? Let's have a graphical error message with actionable help.
Well, it could be done, anyway. If you wanted to follow the spirit of Windows here, it would be the right thing to do, and it'd help users who found a thing that says it supports "Linux" run that thing the way they would hope and expect it to run. Will it actually happen? Not unless someone makes it happen, and convinces distros, desktops and all other stakeholders it's worth shipping, then maintains and improves it going forward. It's a bit depressing when you realize that the technical part of implementing this is basically the least challenging part, at least for a proof of concept.
