The Steam Client Beta has been updated with the following changes: General The Steam client is now 64-bit on Windows 11 and Windows 10 64-bit. Systems running 32-bit versions of Windows will continue receiving updates to the 32-bit Steam client until January 1, 2026.

steam itself is moving towards 64-bit on linux on well, but fact is that most games are 32-bit and linux doesn’t have the same compatibility guarantees as windows since you can just recompile software to run on new systems. you can’t do that with old games, so you need multilib.
I believe wine has a WoW64 implementation now, to allow 32 bit software to run on 64 bit wine prefixes. Which means any windows games (unless they are 16 bit) can work on 64 bit non-multi-arch system.
Linux games are the core problem. But they also have a Steam Runtime where they ship the entire runtime libraries needed to run a game for compatibility reasons… and Steam Runtime 4.0 (which just shipped and/or announced a few days ago?) is set up for only 64 bit systems.
So if the answer is:
Steam itself can be 64 bit, and is moving that direction
Windows games can be 64 bit only due to proton/wine handling the 32bit translation in WoW64
Linux games themselves can be any architecture since the steam runtime manages the libraries for the games.
Then the answer is just “they’re getting around to it, they are only just now getting around to it for windows, and linux is a lower priority” because clearly its all possible.
So “What about linux?” is just asking if there is a timeline for the speed that things are moving in that direction.

i think the wine-wow64 thing is pretty new though, right?
Looks like it was introduced with Wine 9.0 in January of 2024
