Broadly similar to what Apple is trying with their private compute work.<p>It's a great idea <i>but</i> the trust chains are so complex they are hard to reason about.<p>In "simple" public key encryption reasonably technically literate people can reason about it ("not your key, not your X") but with private compute there are many layers, each of which works in a fairly complex way and AFAIK you always end up having to trust a root source of trust that certifies the trusted device.<p>It's <i>good</i> in the sense it is trust minimization, but it's hard to explain and the cynicism (see HN comments similar to "you can't trust it because big tech/gov interference etc) means I am sadly pessimistic about the uptake.<p>I wish it wasn't so though. The cynicism in particular I find disappointing.
