Its kind of crazy how much MGS2 Colonel AI resembles modern AI. He is convincing but just occasionally outputs a bunch of garbage that he thinks makes sense based on the inputs he got from past data in MGS1 and MG2.
Its exactly like modern AI systems. They make sense at a glance but if you push them they crap out and reveal how rubbish and unreliable they really are.
I find it kind of amazing because in 2001 they didn't really have any concept of AI did they? If they did it was a very niche topic that few people really knew about. But to accurately depict what modern AI would be like over 20 years later is quite something.
