If you can’t program it, you haven’t understood it.

To me quantum computation is a new and deeper and better way to understand the laws of physics, and hence understanding physical reality as a whole.

If we can't program it, we can't understand it.

Every problem that is interesting is also soluble.

The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.

The brain is the only kind of object capable of understanding that the cosmos is even there, or why there are infinitely many prime numbers, or that apples fall because of the curvature of space-time, or that obeying its own inborn instincts can be morally wrong, or that it itself exists.

I myself believe that there will one day be time travel because when we find that something isn't forbidden by the over-arching laws of physics we usually eventually find a technological way of doing it.
