Over at the CRN website they have a guest post by author David Brin on nanotechnology ethics:
What I find relentlessly tedious (and, alas, ubiquitous) is the tendency to assume that the objective is actually to see ahead. It is not. The objective is to do what Einstein called gedankenexperimentation: pondering the range of possibilities in order to pick our way ahead, knowing full well that we will only reduce — never eliminate — the number of snakepits that we’ll trip upon, along the way.
