That's high praise coming from a skeptic like you so I appreciate it.

It's not too late. You can still say it. If the word gets out, then
maybe math literacy will increase.

For playing go, perhaps . . . for figuring out new and creative ways
to dodge predators while finding food and mates, probably not.
Airplanes might fly better than birds, but they are not yet smarter.
The human brain is not so much a single neural network as it is
multiple interconnected neural networks built on top of one another.
Like cities in Europe being built on top of ancient Roman forts.

Yes. Birds in general are marvels of evolution. Ravens and Parrot-kind
including the kia, have some of the densest brains known. They have as
many neurons in their much smaller skulls as ungulates like horses do.
I imagine the trade off was fewer glial cells or something.

The adaptations of birds are incredible, especially their extended
respiratory system. The air sacs in their hollow bones operate like a
second set of lungs. Every time a bird exhales, it is exhaling air it
inhaled 2-3 breaths earlier and every last bit of oxygen has been
pulled out of it.
