We haven’t got to where we are today because of our muscles. If you compare us to the rest of the animal world, our physicality is pretty hopeless. Linguist Dereck Bickerton speaks of the haplessness of early humans: “It is more than likely that some of our ancestors suffered the ignominious fate of being eaten by weasels. Some of them, it’s pretty certain, were eaten by birds.” I mean come on, that’s pretty sad. Getting eaten by a lion has at least some degree of gravitas, dying in the jaws of a weasel, that’s just embarrassing. So no, we aren’t where we are today because of our muscles. We’re here because of our brains.

Evolution did great work. Our brains got bigger and bigger and we became more and more like we are today. But our brains could only ever be so good and so big. After all, our mothers are bipedal and consequently endowed with narrow hips. Humans are not very well designed for large headed babies. So for years we bumbled along with our pretty big brains, mostly content with our abilities as a species. Until along came computers, an innovation that revolutionised the horizon of what we could achieve. Computers extended our brains beyond our own biology and into silicon chips.
