It’s not that simple. Proton implements the Windows API functions required to run a Windows game on x64-based Linux, but it’s not a CPU emulator. Emulating x64 on ARM at the speeds required by a game is virtually impossible.
If Steam comes to ARM / Android, it would have to be a whole separate ecosystem of games. But Valve is late to the game there since we already have several players on that market, not least the standard Google Play Store.
I think what you need is Britt Hartley and her book No Nonsense Spirituality. She understands the common elements of different religions that are important to us psychologically, and explains how to bring them into your life without the need for faith in a particular deity.
