Future of SW development

This article talks about the future of SW development and seems to be biased towards Agile development methodology. The main issue I see with Agile methodology is that it is overly person dependent. If you have really smart people, Agile would be great but then in reality you dont always get the creme de la creme. In any case, I think both Waterfall and Agile have their own advantages and scenarios where they would work best. How do we determine which works best when ??? hmmm thatz a million $$ qn and the correctness of your decision on that qn is proportional to your experience
