@futurebird For me, the line is between clever - someone who knows a lot of things, whether through exceptional memory or a great deal of study - and intelligent - someone who can understand new problems and solve them. Clever is fine for some tasks and hopeless for others. Intelligence is much more flexible - and can seek out the relevant knowledge they don't have.
As for the technology equivalent, LLMs are a version of clever, generally minus the awareness of whether they are right or wrong!
