AI does not understand "sexy"

Machine learning algorithms can uncover complex patterns in the data they see, making them useful for image recognition, predicting customer service questions, or recommending movies. They can even do a decent job at naming craft beers, kittens, or guinea pigs. But one thing it turns out they're bad at? Understanding what humans find sexy. I had my first sign that this was a problem when I trained a neural network to generate new Halloween costumes and saw its attempts at the "sexy" category of names - it came up with ideas like Sexy Gargles, Pretty zombie Space Suit, and Sexy the Spock.
