That also explains why they haven't taken over the world yet :)

  It really does. Given how smart, versatile and dextrous the octopus is, its impressive array of senses, and its highly creative use of tools, I can only conjecture that the ocean environment is not conducive to an accretion of technology. I.e. the corrosive ocean water makes the possibility of complex technology difficult, so the octopus hasn't been able to evolve into a longer lived, more socially cooperative creature. Fire, chemistry, long term construction ... impossible or difficult. Because otherwise they seem to have everything. Even latent social ability, despite their typical loner existence. Another impediment is that hiding (their unshelled tasty soft bodies) really well is one of the hallmarks of their intelligence. That would tend to preclude tight cooperative social groups.
