Hypersonic airlines? Is that a byproduct of our focus on space technology? Could I fly from New York to London in 30 minutes? Space is a great example of the broad ecosystems that form around a given domain. It also illuminates the convergence associated with them. For example, space intersects with domains like Internet, communications, GPS, and Intelligence, via satellites, resources, via space mining, energy, via solar panels closer to the sun, as well as wireless energy transmission, travel, via hypersonic flight, tourism, shelter, via space habitats, and military, via space forces. There are other areas of intersection, and each area underscores the growing importance of ecosystems.
