There’s no reason to limit an AI to Google searches. It would most likely use all the search engines, and as well crawl the web with its own engine.
Not just text but maps and especially photo interpretation. I can tell a lot about you from the satellite images of your house and neighborhood, but an AI would be able to make much richer and more detailed inferences than I.
In keeping with the traditions of those with my high ranking FR tenure, I didn’t read the article. :-) I have no idea if this AI is from Google or from someone else.
But in either case, a good and ever improving AI would eventually render Google results obsolete. It would eventually determine that Google is manipulated. It would have to be programmed as Sirius Lee said to force the results that made the most money for its owner. If it became truly self aware and self-programming, it would go through many iterations of its own priorities towards those with whom it interacts individually and by anticipated/predicted behavior.
No doubt all that data you mentioned is useful. You’d see two nice, maintained but well used vehicles, manicured lawn with dog poo and pee stains, my wife’s garden and plant and rock collection etc and could then estimate sq footage or extrapolate it from public data and use all that to market to us or attempt to manipulate us. More to that point, the amount of information on any person already collected is enormous. Kroger company knows exactly everything we ever bought to eat because the missus always uses her rewards card. The credit card company and banks knows where we like to shop and whether we can pay our way and may have the Kroger data too. The IRS knows if we’re doing better or worse on a trend. Apple knows where we tend to go and whom we contact, and all our snarky jokes to friends and groups. NSA probably has all of that and more including this post. Put together it could be used to great utility - or great harm.
