It will never happen, but my dream is for the Asahi devs, Valve, and Apple to all get together to build out a cross-platform Proton to emulate and play games built for Windows on both x86 and ARM hardware running Linux.
A Steam Deck with the performance and power efficiency of an M-series ARM chip and the entire library of games that run on Proton is just...dreamy.
The end game for Valve isn't Steam Deck 2 or 3 (which is statistically impossible for Valve to produce), but for Steam to be on everything.
I empathize if you don't like any version of Windows newer than 7 or XP, but it's time to let the dream of running them forever go. It's not weird when software doesn't support the 2009 version of an operating system anymore in 2024. If they never dropped support, it would be difficult to take advantage of improvements that occurred in the last 10 years, because we'd forever be stuck in baggage.
Of course when it's feasible everybody loves software that really never does drop support, like 7-zip, which I think happily still works on Win9x without KernelEx... but I'd rather 7-zip stopped having serious security issues than continued to work on old Windows versions.
