“SWA Magazine: Talking about spacecraft, what do you think about the shuttle program?
Asimov: Well, I hope it does get off the ground. And I hope they expand it, because the shuttle program is the gateway to everything else. By means of the shuttle, we will be able to build space stations and power stations, laboratory facilities and habitations, and everything else in space.
SWA Magazine: How about orbital space colonies? Do you see these facilities being built or is the government going to cut back on projects like this?
Asimov: Well, now you've put your finger right on it. In order to have all of these wonderful things in space, we don't have to wait for technology - we've got the technology, and we don't have to wait for the know-how - we've got that too. All we need is the political go-ahead and the economic willingness to spend the money that is necessary. It is a little frustrating to think that if people concentrate on how much it is going to cost they will realize the great amount of profit they will get for their investment. Although they are reluctant to spend a few billions of dollars to get back an infinite quantity of money, the world doesn't mind spending $400 billion every years on arms and armaments, never getting anything back from it except a chance to commit suicide.”
