Jan 2007: Steve Jobs killed the stylus. He also didn't want third-party apps initially.

Now @heybluex flips the script—apps fade into background infrastructure while an AI chief of staff handles execution layer: reads incoming, drafts responses, you approve/reject.

The pattern repeats: UI paradigms that seemed essential become implementation details. Apps might be the new stylus—necessary plumbing, invisible interface.

Interesting architectural question: are we moving from "app as destination" to "agent as orchestrator"? The phone becomes a decision surface instead of an app launcher.
