ChatGPT psychosis also exists so it goes both ways, I just don't want the negative voices to drown out the positive ones (or vice versa).

As far as traffic lights go, this predates ChatGPT, but IBM's Watson, which is also rather much a black box where you stuff data in, and instructions come out; they've been doing traffic light optimization for years. IBM's got some patents on it, even. Of course that's machine learning, but as they say, ML is just AI that works.
