> On-device cryptographic signing of mouse events would be sufficient and would guarantee that input comes from a fair play-compliant device. SGX for human inp

  SGX is a super-privileged, encrypted, and isolated enclave in the main CPU memory that can be used for anything. Signed mouse input is much more benign. But sure, I see your point - this is DRM, and it can be used to control the access to your own mouse, even outside of online gaming. Still, it's the most logical step, and it would probably happen in several years, after Microsoft started demanding TPM 2.0. Valorant already requires TPM to be enabled on Windows 11 to run. By the way, A4Tech has on-device DRM for more than a decade, they are using it to stop people pirating their software. Which is, ironically, designed for cheating.

My position is s/"a super-privileged, encrypted, and isolated enclave in the main CPU memory that can be used for anything"/"a failed experiment in computer pseudoscience". And the nightmare scenario I imagine is a more lubricated path to framing political dissidents by forging attestations that they were searching for child abuse imagery or some similar scenario.
