I think one of the problems is the wild
speculation that Drexler and other advocates make. For instance, the chapters in Unbounding the Future and Engines of Creation which talk about reviving dead species and repairing the Earth. While this may well be possible, it's premature to make claims without looking at the economics involved. Also, as can be seen with the
Nanomedicine FAQ, claims that abundant health will create peace. Seeing such naive and utopian claims (especially if they're the first contact you have with the technology) can colour your attitude about its feasibility.
