I posed this exact question to character.ai's "Ask Me Anything" bot. It decided to redo the examples, too. The results: > Lane, Thomas => Thomas Layne > Brooks, Sarah => Sarah Brooksy > Yun, Christopher => Chris Yun > Doe, Kaitlyn => KD > Styles, Chris => Chris Spice, Chris Chasm I'm sure the bot overcomplicated an otherwise simple task, but I think there's always gonna be some creative error if we rely on things like that. It's funny though because these results are plausible for what a real person might come up with as informal nicknames for their friends.
