> I was very confused, and reasoned that the most likely explanation was that I had subconsciously been liking dog videos in our run-up to getting a puppy. But then it occurred to me that it's quite realistic to think an ML model got me: I'm logged into tiktok via Google as myself; there's certainly data sharing agreements in place; my purchasing habits are no doubt tracked by multiple vectors; and I know from experience that ML can infer some surprising things from sparse data. I think the answer is probably more mundane: someone an edge away from you on their social graph looked at dog videos, and they correlated it based on that.
