Machines built by human beings they will function correctly if we provide them with a very specific environment. But if that environment is changed they won't function at all.

One of the things that we can say with confidence is that we will have much lighter, much stronger materials, and this will reduce the cost of air flight, and it will reduce the cost of rockets.

Machines built by human beings they will function correctly if we provide them with a very specific environment. But if that environment is changed they won't function at all.
