Yet I still think your study was a microcosm of the greatest dangers I think about AI. That is, it was astoundingly good at doing small scale feature detection, but astoundingly bad at synthesizing an overall conclusion, and worse, it did so with characteristic "AI certainty". Also, in the real world just like you found, pictures have glare, and real manufacturers have mistakes. The horrifyingly scary thing is that even if you think Gemini did a fairly good job at feature detection, in the real world people have and will just follow the AI conclusions blindly because they're "mostly" correct, even when they lead to completely wrong outcomes.
Heck, a Tesla already killed its passenger when it rammed into the side of a truck a few years ago because it mistook glare on the truck for the sun. Military planners blew up a school of young children based on old data, yet the Pentagon tried to blacklist Anthropic because Anthropic didn't want to provide autonomous kill capabilities.
I don't mean to sound over dramatic, but again, to me your study highlights everything I think is wrong with AI and the extreme dangers it will cause if society relies on it too much, which it has already begun to do.
