I mean, Google and x.AI already have stuff like this. There's plenty of other options as well. And even outside of that, I've heard the promise of "let AI book your reservations!" since before LLMs became a thing.
None of this seems new. Maybe polished, but useless to anyone who is seriously using AI for anything important. I imagine this is effectively a toy for boomers who want to feel like they're keeping up with the latest tech by tapping a few buttons in Facebook.
And none of that even touches that fact that nobody should be OK with Meta having this kind of access to their life. But I'll leave that to others to harp on lol
