IMO we are going to see a large class of people who have cognitive deficits brought on by AI tool usage.

I've been wondering lately about how to distinguish between tools that enhance your cognitive ability, and tools that degrade it. Jobs called a computer a "bicycle for the mind," and it seems like LLMs are an easy-chair for the mind. I'm not sure a priori how to distinguish between the two classes of tools though. Maybe there is no other tool like an LLM.
