I believe in the "10x programmer" phenomenon.. In my experience, the best programmers seem to quickly become very good at whatever development task they put their minds to.
Then you may need to consider the possibility of a "100x" programmer in your scale. The "best of the best" that I know are, say, 10x better at embedded C code than they are at CRUD web apps. The best CRUD programmers I know can't hold a candle to the best embedded programmers in their domain and vice versa. At the high end of proficiency, programming is not a commodity. Specialization matters.
