Those with one track minds tend to excel specifically at the one track they dedicate themselves to while failing at other things. There are also those who are good at many things. Both have valuable skills (and both are actually well compensated and highly necessary for companies, IME). But if you want to be that guy who can just crank out code for any problem, then I believe this ability is based on the amount of time you've spent coding, which, for those who have one-track minds, is naturally going to be a lot more than the average programmer. It takes all types. There is no value judgement in my descriptions.
