>What changed?

Motors, electric or otherwise, made it so you can jump in a car, or a bus and drive you and your friends to the movies or on a holiday and go out and see the world. LLMs make it so people end up like delusional zombies talking to a screen.

Nothing has changed about people, they had common sense then and they have common sense now and they recognize when you try to sell them something useful that makes the physical world and their social situation better and when you want to sell them something out of dystopian sci-fi novels.
