The other major obstacle is their reproductive cycle. Octopodes breed once, then die shortly afterwards. They don't live to pass knowledge on to their children, and there's no reproductive "reward" for individuals that are more successful in life -- so long as they survive to breed, that's it.

Yeah, that's part of the same thing, for sure. They don't share knowledge with other adults or with their own children, so nothing gets passed on.
