  • I dreamed of a friendly machine to which you could delegate all those manual tasks which are prone to errors. A machine that could quietly learn and perform tasks, that could store simple data and instructions, that could be used by anyone, that would be inexpensive and the size of other office products which people used. I had to create a new language which did not need interpreters in white coats.
