Did you know that knowledge is the ultimate form of power in the universe? That's what David Deutsch argues in his podcast episode on knowledge creation and the human race. He explains that understanding how knowledge is created is essential to understanding the physical universe. There are only two systems that create knowledge: evolution and humans, with the latter being the ultimate form of knowledge creation. While biological evolution is limited in its range due to its lack of foresight, human creative thought has the power of explanatory creativity, allowing for the creation of things like campfires and space travel. In fact, humans have the unique ability to imagine things that don't exist and create something that's a culmination of a whole load of non-viable things. So, not only are we the ultimate creators of knowledge, but we have the power to do things like get to the moon and cause asteroids which are heading towards the Earth to turn around and go away, thanks to our explanatory creativity.(Time 0:05:25)
