Exactly - a great programmer would put his/her ego aside and become any one of these stereotypes if the situation demanded it.

Sometimes it may be prudent to keep some old tech running. Other times it may be better to push the boundaries of new tech. A strict methodology might work great in one situation, whereas a lone wolf might be better in another.

Really the only that that is consistently bad is if you just don't care or you don't put in the effort.

I should point out - using an old legacy technology is not the same thing as being an Arcanist. These archetypes all have one thing in common: taking a normal, routine thing that programmers encounter in their careers and take it to an extreme.
