Since Google is primarily a surveillance advertising company, it sadly means that AI will be used to surveil and advertise to people. Ad content (and "editorial" content) can be chosen by an AI based on your surveillance profile.

Google will sell these features to advertisers as "better matching" their customer profiles, but in reality surveillance advertising isn't any more effective than the older, anonymous kind. Companies like Google and Facebook act as a tax on the market, forcing any serious players to come to them and pay the advertising tax. Both companies will use AI to try and continue to stay in those monopoly roles.
