I had something crazy like this happen recently. A friend of mine sent me a photo to my personal phone of an expensive liquor. The very next day on my work computer, on my work network, YouTube suggested a short video about the same expensive liquor that I had never looked anything up about previously.
How the hell a photo from on device managed to track me like that was impressive. The algorithm is watching us.
Consider 9/10ths of my Gmail messages are probably written by AI, I’m not worried.
