As I said in my other response, I make heavy use of trusted (confidential) VMs for machine learning in cloud environments.

There are also vendors that are doing smart contract execution in trusted computing devices so you can get the benefits of trusted execution without the overhead of everyone executing the same code.

There are a handful of potential uses for confidential VMs, but not many of them really seem to make sense on phones?

The issue here isn't the technology though, it's imagination.

Think about gaming in VR. You might want to make a game where the ML can adapt to the physical peculiarities of a person (think like personalized audio for airpods) but want to guarantee it isn't giving the person an advantage. Even simple things like setting up a VR system (or any physical computing device) can give an advantage to someone if corruptible.

At the moment there are lots of "anti-cheat" technologies that attempt to solve this, but really it needs trusted execution.
