(CNN) Prince William slams space tourism and says billionaires should focus on saving Earth.

Bravo, Prince William! Space tourism is an ego trip; a hyper-expensive view out a window, well mimicked in virtual reality – except for the chance of an exotic death.

Carbon based life is unsuited for space exploration. Androids, resistant to radiation, who will not require air-water-food life support systems, will take our places.  Androids will have the ability to experience, and relate experience, which is the only thing robots currently cannot provide. And they are expendable.

Until this rapidly approaching future, the extreme cost of manned space flight should be reserved for more than flights of fancy. The Tsiolkovsky/Goddard rocket equation enforces a huge carbon cost, with no solution on the technological horizon. This severely circumscribes the economic exploitation of space.

Freed by androids of the huge incremental carbon-cost burden of life support, some small subset of hopes for economic exploitation may be viable.

Or maybe not. The odds favor Prince William.
