According to Steam: in the last 3 years there has been 150% growth in Linux users
Steam deck.
The Steam deck is less than 10% of Steam’s linux installs. It identifies as Arch, and that category also includes Arch, which is a popular distro in general. The 150% growth in Linux users is certainly helped by the Steam Deck, but it isn’t the primary growth driver. People are simply using Linux more and more as Linux continues to improve and Windows backslides.
From Steam’s hardware survey:
Linux runs most of the world’s servers. It’s pretty damn stable. One of the reasons it is generally chosen over Windows for servers is specifically because of its stability.
I’m not telling you to use it, mostly just this concept of instability is off.
