It would just be great to get in a decent chip that does not have built in, and unblockable, back-door hacking, like those on Intel, AMD and probably ARM.
I see a good opportunity for government to make this a reality. Not per se a fan of gov regulation for many things but I don't see this moving forward very fast. There are initiatives left and right (e.g. Talos) but if a significantly large government body (EU?) would make it a requirement, that might change the game. Lobbyists would probably convince them otherwise (you need closed HW to catch terrorists... etc).
