Mathematical reasoning may be regarded.

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

No, I'm not interested in developing a powerful brain. All I'm after is just a mediocre brain, something like the President of the American Telephone and Telegraph Company.

Sometimes it is the people no one imagines anything of who do the things that no one can imagine.

We may hope that machines will eventually compete with men in all purely intellectual fields.

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

Up to a point, it is better to just let the snags [bugs] be there than to spend such time in design that there are none.
