Sure, perhaps in 60 million years we’ll be extinct and Octo Sapiens will be colonizing Alpha Centauri, but today right now on this planet the gulf in intelligence between humans and the other creatures is gigantic.

I think this lines up with what I consider intelligence. The "we" is the human race and most of us acknowledge we are the most intelligent life on Earth using the measure we invented (retaining, passing on, and using knowledge). I won't be convinced otherwise unless some other being out there proves to us that they can do it better.
I’ll give up and admit defeat, but I still think it’s stupid to dismiss animal intelligence. Perhaps some day we’ll discover how to communicate with octopi and we could then work with them, perhaps. Call me crazy, but imagine we could work with them to go to places humans couldn’t because of needs we have that octopi don’t? Maybe it’s easier to send them to the nearest star, or something, I don’t know.
