Nanotech Grab-Bag

Are molecular assemblers feasible? As I pointed out here, an Israeli team has reportedly used a DNA molecule to assemble a transistor.

Yesterday, Glenn Reynolds posted a wealth of links on the debate over the feasibility of nanotech molecular assemblers. I like how he works Clarke's first law
into his commentary, too: "When a distinguished but elderly scientist states that something is possible he is almost certainly right. When he states that something is impossible, he is very probably wrong."

Lots of good stuff there, so read the whole thing, along with the linked articles.
