Physicist: Computer scientists have done nothing for quantum computing.This becomes a self-fulfilling prophesy. Once computer scientists have done something physicists care about they cease to be computer scientists and are now physicists.
Computer Scientist: What about Shor's quantum factoring algorithm?
Physicist: Peter Shor is a physicist.
This view has changed a bit, now we do see a number of physicists (though certainly not all of them) seeing value in many of the tools, techniques and results from computer science. We are also making headway in other fields like economics and biology.
If we want computer science to continue to prosper we need to continue to reach out to other fields and do our best to make them understand the role computer science can play in helping understand their basic questions.
