Why build an AI thinking partner

So what is a PM AI thinking partner? I've been using my AI thinking partner every single day, multiple times a day for really big strategic decisions, for hard conversations and preparing for them by simulating them, and of course, for routine PM tasks that I would love to hand off like meeting agendas, summaries, communications, internal messages. Plus what most of us have been using AI for as PMs - writing documents and product artifacts like PRDs, API docs, user stories, and so on.
