Well I would disagree that anyone would get to that level. Some folk just never seem to learn how to properly build and maintain a software project. Sure though I agree that any virtuoso coder should branch out to mentoring and architecting as that's basically expected of them having the experience.

Yet I don't know hour-wise how much they'd have to put in having meetings if they already kinda know how to build the system. I don't think that would necessarily be scary to them, just annoying if they had to be constantly distracted by having to mull over details that aren't that important.

To me a virtuoso is the consultant who knows how to build all parts of the project who is not there to lead the team but will help out anyone in the project - and will take care of it being built properly.
