For years I thought Mickey Rooney (1920-2014) and Mickey Rourke (1952-present) were the same guy. I'd see Mickey Rooney in a movie and be like "Wow, he's looking pretty good for his age," thinking he was a man 32 years his senior and/or dead.
I finally twigged when I eventually saw Iron Man 2 (2009) and was like "How is he doing this?!" and actually looked him up.
I do wonder whether the algorithm understands sarcasm. A while back, I watched a video about some movie bombing, something objectively bad like Morbius, and they joked that the movie wasn't actually failing for all of the obvious reasons, but because it was "too woke". They didn't really believe that, they were just making fun of people who say that about movies. Still, for the next couple of weeks I had to keep marking channels as "Don't recommend" because they were all unironic right-wing rage-bait about the woke agenda. I don't know for certain that that's why I suddenly got all those recommendations, but that was my best guess.
