Humans paid by the robots

Not a new story, but the New York Times reports some interesting details (including prices) of human farms hired by robots (well, not really) to solve CAPTCHAs.

Macduff Hughes, at Google, captures the main point I've been making for years: screening out unwanted intruders is an economic problem, and CAPTCHAs are an economic (signaling) mechanism, trying to raise the price sufficiently for bad guys to keep them out.
