To me, knowledge is about knowing things, intelligence is about being able to apply your knowledge at the right context and for the right reasons.

The current crop of LLMs has a lot of knowledge, but severely lacks on the "intelligence" part. Sure, it can "guess" how to write a unit test consistent with your codebase (based on examples), but for those 1% where you need to make a deviation from the rule, it's completely clueless how to do it properly. Guessing is not intelligence, although it might appear masked as such.

Don't get me wrong, the "guessing" part is sometimes uncannily good, but it just can't replace real reasoning.
