It is hard to believe that it has only been about a year since travelers started dabbling in ChatGPT-created itineraries.

Breana Newton, a legal coordinator in Princeton, N.J., who posts regularly about books on TikTok, was one of the people who responded to Ms. Blalock’s video. “I am going to show you bookshelf wealth,” Ms. Newton, 33, says in a video of her own. “Ready?”She then gives viewers a brief tour of her home, showing books everywhere — on shelves, in overflow piles here and there, and strewed across the bed.
