I have seen the science I worshipped, and the aircraft I loved, destroying the civilization I expected them to serve.

Machines seem to sense that I am afraid of them. It makes them hostile.

Inventions that are not made, like babies that are not born, are rarely missed.

The real problem is not whether machines think but whether men do.

The belly is the teacher of the arts and bestower of invention.

You cannot endow even the best machine with initiative; the jolliest steamroller will not plant flowers.

The art of invention grows young with the things invented.

The civilized man has built a coach but has lost the use of his feet.

Civilization, a much-abused word, stands for a high matter quite apart from telephones and electric lights.

One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.

All technologies should be assumed guilty until proven innocent.

When poets don’t know what to say and have completely given up on the play, just like a finger, they lift the machine and the spectators are satisfied.
