"How it actually functions" is too much of a moving target. The book of "best practices for building AI agent functionality into your OS" is still being written. But "sandboxed envs for AI to do things in" is one approach MS is currently trying for.

I agree that a "good" implementation of agentic AI can have a lot of benefits, to casual users and power users both. But do I have any trust in Microsoft being the company to ship a "good" implementation? Hell no.

Windows has been getting more and more user hostile for years now, to casual users and power users both. If there's anyone at Microsoft who still cares about good UX, they sure don't have any decision-making power. And getting AI integration right is as much a UX issue as it is a foundation model issue or an integration hook issue.
