a few comments on scientists and their expertise

Two quasi-offsetting comments on whether we should pay attention to scientists when it comes to public policy. They don't seem to think they are particularly neutral, even if we think they are. A few retorts to the Pew poll.

Also, an interesting post on Moore's Law and all of it's cousins. Also, thoughts on why it doesn't seem to apply to all areas of science/technology. (Hat tip Marginal Revolution) Or maybe it does, just not at such a sharp curve as with computing power. What causes it? Will it end? Etc.
