I can't imagine that life can be replaced with a computer universe. I can't accept it.

I have not proved that the universe is, in fact, a digital computer and that it's capable of performing universal computation, but it's plausible that it is.

At this present time, matter is still the best way to think of architecture, but I'm not so sure for very long. The computer is radicalizing the way we think about our world.

I just think there's a general interest in the world of computers.

Computing is not about computers any more. It is about living.

The big question society will have to answer is whether it wants computers thinking like humans.

The brain-mind is not a computer, and regarding it as one has led to a variety of theoretical dead ends.

The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.

If you wanted to build the most powerful computer you could, you can't do better than including everything in the universe that's potentially available.
