Is Information Architecture Dying?

Anthony Viviano at Organic asks if Information Architecture is dead, continuing the discussions about the inclusiveness and expanding scope of IA vis-a-vis UX, and hopping on the question about interaction design being a dead end job. Clearly, he doesn't think the practice and craft of IA is dead, just as the craft of Interaction Design is clearly alive. But the role is changing, and while the navel gazing gets resoundingly loud around defining things, the definition of the shifting roles and responsibilities in the field is meaningful.
