Maybe you've created your own AR program for wearables that shows the definition of a word when you highlight it IRL, or you've built a personal calendar app for your family to display on a monitor in the kitchen. Whatever it is, I'd love to hear it.
I'm not convinced the costs would make that a viable use of resources versus just making an appropriate product, or using something that already exists like Spotify playlists. Even an LLM is expensive to keep running.
But we aren't there yet, and grandma is going to be dead in a decade, and the source code for the radio playlist gimmick already exists, as does Spotify.
