This is not remotely true, to the point that I don't even understand how you could assert it. What skills taught to physicists or chemists or biologists are even related to notions like modularity and data abstraction? Hell, I've seen people come out of computer science PhD programs with poor software engineering skills and habits. If CS programs don't reliably teach these things, how can you claim researchers in other fields automatically have them?
