When I was a tortured young child, my private hell was that others were actually robots put on earth to abuse me and drive me crazy. But I didn't know how to tell for sure that someone else was a robot. So using the Voigt-Kampff test to tell humans from replicants in San Francisco's mayoral race seems like a good idea to me. :)
By the way, the putative author of the article has the same last name as the Blade Runner character blown away at the beginning of the movie. Coincidence?
