In the documentary, Ultimate Mars Challenge, we learn of the cutting edge engineering that went into designing the Curiosity Mars rover. This shows us what we can accomplish, so why do we so often settle for less?
Why do we settle for archaic, inefficient combustion engines in our cars? Why do we accept claims that fusion energy is always fifty years away? I remember many years ago plans were made for humans to explore Mars in 2019, which seemed a long way in the future, and yet here we are. We brag about how much computing power we carry in our pockets, but what do we really use it for?
Why do we settle?
