AI always answers the same too, if the inputs are the same. The trick is to use a hidden input that keeps changing, like the current time, and you can do the same with any algorithm.

AI is just a really advanced algorithm. (Or sometimes not so advanced, if you include types of AI that aren't LLMs.)

Also, AI is behind almost all algorithmic content delivery. You can just google it and find articles like How AI Influences What You See on Facebook and Instagram. Every closed-source platform is using it, except maybe reddit, but that's only because they have a ton of technical debt that makes it difficult for them to change core systems.

Of course it's true that AI is "just" a tool, but it's a tool that makes it a lot easier to manipulate people, and it's already a huge problem.
