> requires human presence
I'm not using the secure enclave, but I've been using YubiKeys for many years, and now that AI has arrived, I consider the above to be a good thing.
This means, for example, that unless I am physically present with my key inserted, activated, and touched on every operation, an AI agent cannot access any of my production servers. As I do not want AI agents to access my production servers, this is a very good protection technique. I am assuming that no matter how well you try to sandbox and restrict your AI agents running on your local machine, they might eventually be able to access any file in the file system.
