Plus they live very short lives, giving less opportunity for the accumulation of a lot of knowledge.
Their reproduction strategy and life cycles also basically don’t allow for generational interaction: most octopuses reproduce only once, produce tens of thousands or even hundreds of thousands of offspring, and die shortly after reproduction. Then the young paralarvae drift as plankton until they grow large enough to settle wherever on the sea floor they happen to be.
