An AI-powered weapons scanner meant to create "weapons-free zones," fails to detect knives. A New York school district bought the nearly $4 million system and then found out it didn't fully work. It spent close to $4 million to buy an AI-powered weapons scanner from Evolv Technology that the company bills as "proven artificial intelligence" able to create a "weapons-free zone." Evolv Technologies claims on its website that its weapons detection system can scan for weapons 10 times faster than traditional metal detectors. Evolv co-founder Anil Chitkara told WRAL, a news station in North Carolina, that the "AI algorithm is trained on thousands and thousands of different items, different weapons, different guns and also, different personal items, phones, keys, and other things."
