Though both are probably apocryphal:

"I think there is a world market for maybe five computers,"

and:

"640K ought to be enough for anybody."

We're really bad at predicting how things will change. Who would have thought that Tim Berners-Lee would be a link in a chain to Donald Trump's election?

Gobi desert doesn't have 1/3 earth gravity.

What are the economic benefits of low gravity? If so, would the moon be more economically valuable than Mars?

I’m genuinely curious about the economics of doing more in space than putting up satellites.

1/6th of Earth gravity is even better.

Short term: a wonderful tourist attraction. You can nearly fly.

Long term: people with muscular / bone disabilities who cannot withstand Earth gravity. An interesting retiring home (for a narrow wealthy set, of course).

Who is going to pay to fly these sickly retirees to the moon, and then continuous supply them with resources that are literally free on Earth (ie air)? Medicare?

Moreover, if they struggle with earth gravity, how will they survive launch and landing?

By using the space elevator, of course!

For a spacefaring civilization reliant upon chemical rockets, less gravity is better. Point being Mars is a better place for such a civilization, not earth.

I mean obviously you need less energy to move things around. We spend an enormous amount of energy to move things around on earth.
