The second my local AI assistant learned how to operate Windows apps, I ran into a new bug.

Not a model bug. Not a prompt bug.

A traffic bug.

One task was logging into a site through the desktop. Another task wanted to open a different app. Both requests were valid. Both were "in progress." And both were trying to use the same physical mouse, keyboard, and screen.

That is when an assistant stops feeling like software and starts feeling like two interns fighting over one laptop.
