I find it much more likely that Valve enables Secure Boot on their Steam hardware.

I imagine that if this happens, it will be followed by popular Linux distros finally becoming serious about their Secure Boot implementations, instead of simply shimming it or seen as a rarely-used feature reserved for enterprise distros like RHEL.

Some of us actually think that having some sort of validation that our OS hasn't been tampered with is a feature and not a bug. It's only a problem when companies parlay that validation into anti-consumer DRM - but that's a political problem, not a technological one.

It's both a technological and political problem.

All the platforms that went all-in on secure boot like things and attestation are anti-consumer hellholes that slurp all your data. The evidence just does not look good. Maybe Linux is different, but it's swimming against the tide here. It would be the first of it's kind.

But again this doesn’t solve the problem where an AI model can just play the game.

Or rebooting to a secure mode where you can only run the game and maybe discord.

A few anti-cheat systems rather than inspecting the local machine look for things like impossibly fast target acquisition in FPS games, or the server noticing when a shot is taken on an opponent who’s supposed to be totally obscured. Those aren’t perfect, but they don’t require kernel-level anticheat.

Cheating detection server side is expensive and probabilistic at best, kernel level anti cheat is a purely financial decision
