No, it doesn't mean that at all.

I'm not surprised that higher level scientists and engineers are generally more well-rounded than people who are only scientists and engineers by trade. When I look around my peer group, I see a pretty clear correlation between being better at their field, and being more well-rounded in general. Specialization and focus has its place, but in my industry (tech) the people who are "moving the ball" (vs. the break/fix positions) are also more well-rounded, not less, and that isn't limited to tech-specific things at all.

I think the real myth is that scientists and engineers don't appreciate/value/"get" art. The stereotype of the autistic super-scientist just doesn't hold up to real life for me at all, on average at least. Do you like music? Is it for the mathematical purity of the composition, or do you like the way it makes you feel? Congrats, if you picked the latter, you're into the arts.
