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

Our best theories are not only truer than common sense, they make more sense than common sense...

Is the human race a universal constructor?

The most important application of quantum computing in the future is likely to be a computer simulation of quantum systems, because that's an application where we know for sure that quantum systems in general cannot be efficiently simulated on a classical computer.

Feeling insignificant because the universe is large has exactly the same logic as feeling inadequate for not being a cow.

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.

The truly privileged theories are not the ones referring to any particular scale of size or complexity, nor the ones situated at any particular level of the predictive hierarchy - but the ones that contain the deepest explanations.
