Two recent advances are about to dramatically change this limitation. The first is the advent of a commercial space industry that will soon begin taking tens of thousands of people into the near-space environment, far enough to grasp some aspects of the Overview Effect. Zero-gravity flights will make this effect of space travel available to many more. This is only the beginning of the historic human evolution into space, and the resulting transformations of human culture and consciousness as we become a space-faring culture.
The second major advance is the rapid maturation of high-definition digital media, from the internet-connected desktop to three-dimensional simulation media and virtual reality. These new technologies, together with other forms of art, media, entertainment and education will soon provide new and more powerful tools to immerse Earthbound audiences in a close approximation of the space environment and potentially bring the Overview Effect to many millions around the globe.
