I’d rather the psycho have a brain implant that physically prevents him from murder, but I wouldn’t trust such an implant myself fearing abuse or malfunction.
I’d change my mind if the AI was really smart or controlled an agile, dangerous robot. But current-gen AI I’d choose for them over a gun. We’re ruled by psychos (of a lesser degree), the road starting directly towards perfect safety is a dead end, meanwhile I want an LLM aligned to myself.
