There are plenty of intelligent animals and dextrous animals on the planet. The difference between them and humans is that humans can do both.

Nah, the differences are (at least) that we're future-oriented, motivated, social, have language, and live long enough to be grandparents. Take that, octopuses.

Also as far as the economy goes, we actually try to participate in it instead of sitting around getting eaten. Maybe we won't succeed in the future though…
