I’m going to look like a conspiracy theorist, but this is just weird. A bunch of Washington scientists built robo-cockroaches and sent them out to see if they could infiltrate and influence real ones. They had to spray them with pheromones to fool the little crawling critters, but they did it. They say it’s to study the leaderless group behaviour of cockroaches. Is there a bigger picture here? I’d like to think that we’re harder to fool than a cockroach, but….you never know.
