> Okay but suppose you have an AI chatbot which takes in context from previous chats on what your interests are. So people just keep talking with the chatbot more and more as it gains more context. This would meet the criteria. It's not necessarily addictive though because you can stop talking with the chatbot at any time.

You can stop scrolling instagram "at any time", too.

Chatbots are actually a pretty poor but very relevant choice of example: they are already tuned with RLHF to be engaging and addictive to talk to. That's a huge reason why LLM psychosis is a thing, and it's a big reason why some people like using chatbots so much. They're designed to be addictive, just like facebook/instagram/tiktok are.
