I think Proton is the smartest thing Valve has ever done. Thanks to that, Steam is going to get about 90% of all the Windows gamers switching over to Linux.

I look at this and wonder
Why gog galaxy and epic client were ported to macos and linux users still didn't get native game binaries from epic?

I so very much hope that the Linux gaming effect increases. Not only for gaming, but for the productivity world. If development of these 'compatibility layers' (Wikipedia) like Proton, Wine improves and maybe win-native software (thinking of CAD in particular) can be made working reliably on Linux using these packages, one or the other big player might adapt. That would be a much cheaper way of expanding the software's range than developing and maintaining a native Linux port...

... and maybe I am too naive.
