To me it seems like LLMs are basically memory for humans as a whole. By interfacing with them, you can extract the knowledge, eliminating the need to remember things.
And become the perfect puppet for the ruling class! 1984's got nothing on us.
This has been the case for a while with search engines. I'm convinced our brains have evolved (atrophied?) to avoid having to remember things that you can simply look up on your phone in a matter of seconds.
