Agreed. Of course to a degree it matters what you mean by "excel".
In general, an expert program will not be a truly expert sysops because each of them is a deep field and developing truly deep expertise in either of them can be an almost all consuming task.
But, you can easily find people that are pretty good at both, and I would go so far as to say anyone who is good at one also already knows at least the basics of the other, they just might not be a true expert. Certainly anyone who is good at one has shown they have the right mindset and capabilities to become good at the other if they decided to.
