Google knows what "Home" is for me only in Gmaps, because I went out of my way (put a Label etc) to tell it. I want to be able to tell Google "My home is XYZ", and for Google to use that information about me in all of Google ecosystem. When I talk to Gemini it should know what/where "LJ home" is, when I write in Gdoc it should know my home address (so to insert it if I want it), ditto for Gmail, when I search in Google photos "photos taken at home" it should also know what "home" is for me.

I have the impression that we ended up in the worst case scenario. People I don't want to have my data, have access to it. People I do want to have my data, are afraid to touch it, and use it - yes! - for theirs, but also for my benefit too.
