Whether Google is interested in serving me or not, is not only untestable (i.e. what counts as 'Google', 'interested', and 'serving' there - one could argue to end of time) - but besides the point. 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.
Atm Google vaguely knows, and uses that for Ads targeting, sometimes. Most of the time - the targeting is bad, very low quality slop. To the level of "he bought a mattress yesterday, will keep buying mattresses in the next 30-60 days". 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. The current predicament seems to me the case of "public lies, private truths."
A small cadre of vocal proponents of a particular view, established "the ground truth to what is desirable". (in this case - maximum privacy, ideally zero information sharing) The public goes with it in words, pays lip service, while in deeds, the revealed preferences show, they value their data privacy very cheaply, almost zero. Even one click extra, to share their data less, is one click too many, effort too high, for most people. Again - these are revealed preferences, for people keep lying when asked. It's not even the case of "you are lying to me" - no, it's more like "you are lying to yourself."
The conventional opinion is that the power imbalance coming from the information imbalance (state/business know a lot about me; I know little about them) is that us citizens and consumers should reduce our "information surface" towards them. And address the imbalance that way. But. There exists another, often unmentioned option. And that option is for state/business to open up, to increase their "information surface" towards us, their citizens/consumers. That will also achieve information (and one hopes power) rebalance. Yes there is extra work on part of state/business to open their data to us. But it's worth it. The more advanced the society, the more coordination it needs to achieve the right cooperation-competition balance in the interactions between ever greater numbers of people. There is an old book "Data For the People" by an early AI pioneer and Amazon CTO Andreas Weigend. Afaics it well describes the world we live in, and also are likely to live even more in the future.
