Of course Google uses it to drive their own ad engagement. Say you want to look up your flight info. Instead of going back to the original email, you have all the info in the assistant. Instead of seeing rental car ads from the airline, you get them through Google.. You get to check out attractions in the city you're visiting through Maps.. it's obviously not all 1:1. Google isn't so pushy with their ads. They like to be subtle. But yea, they clearly get to serve more interesting ads by hijacking these workflows. Slightly less obvious what they do Amazon toilet-paper receipts. Often things can just be aggregated into really good business intelligence. They could data mine what shows netflix is recommending, etc. I'm honestly not sure what kind of protections they offer in terms of extracting aggregate data from email. It's creepy so they'd keep it mostly internal.. but I'm sure they would have found some really interesting ways to use it.
