While humans are still afraid of artificial intelligence, a new threat has quietly emerged from an unexpected direction. Neuroengineer Victor Tot has updated his experimental platform for testing rodents, and now rats in Doom II are not just wandering around, but are actually engaging in targeted shooting. The rats have access to panoramic screens and motion sensors. If a rat crashes into a wall, it is gently blown a gentle breeze, and for each successful kill, the rat is rewarded with a tasty treat. The authors emphasize that this is not a demonstration of the rats' conscious understanding of the game, but rather an experimental platform for studying animal behavior in virtual environments.
