Unless in communicating with it one says exactly what one means, trouble is bound to result.

If a machine is expected to be infallible, it cannot also be intelligent.

One day ladies will take their computers for walks in the park and tell each other, "My little computer said such a funny thing this morning".

It seems probable that once the machine thinking method had started, it would not take long to outstrip our feeble powers… They would be able to converse with each other to sharpen their wits. At some stage therefore, we should have to expect the machines to take control.

There is, however, one feature that I would like to suggest should be incorporated in the machines, and that is a 'random element.' Each machine should be supplied with a tape bearing a random series of figures, e.g., 0 and 1 in equal quantities, and this series of figures should be used in the choices made by the machine. This would result in the behaviour of the machine not being by any means completely determined by the experiences to which it was subjected, and would have some valuable uses when one was experimenting with it.

A computer would deserve to be called intelligent if it could deceive a human into believing that it was human.

A man provided with paper, pencil, and rubber, and subject to strict discipline, is in effect a universal machine.
