I can't imagine your level of cynicism. I've only been at this for ten years, and the number of times I've seen the wheel come full circle and old ideas come back into vogue, the problems with them rediscovered, reactions to those problems, and then the thing that preceded them again take precedence is somewhat depressing. At best I feel like we are grinding ahead a few inches each cycle.
