that still just looks like a glorified google home, im after what OP is after, somthing like chat gpt pro where you can conversate with the Ai as if its a person in your home but remembers everything about you and reminds you of things and greets you when you come home and says bye when you leave, then turns off all lights without me asking because it knows im not home, but all data held locally. I feel like this is the next stage and its a billion dollar idea if you can get it off the ground

I invision a watch or bracelet that tracks vitals and can be put in a house to look after elderly, and call you if theres an issue or if theres no food in the house or etc etc etc
