Octopuses may be so terrifyingly smart because they share humans' genes for intelligence.
Perhaps if Octopus were in control of the world we would have a cleaner place to inhabit.
I think a lot of species have more intelligence than humans. We're a dopey species with inexplicable destructive behavior.
We apparently all ha e the same gene structure, what we are is determined by which are turned on and off.
We keep screwing up maybe they can take over. They would be hard pressed to do a worse job.
