The statement IS true anyways, the problem is that you failed to distinguish between an example and a universal claim. You want to argue on logic? I'm an engineer, I can argue on precision too:
The (true!) statement is "However, there's an immense difference in scale between post-industrial strip mining of resources, and preindustrial resource extraction powered solely by human muscle (and not coal or nitrogylcerin etc). Similarly, there's a massive difference in information extraction enabled by AI, vs a person in 1980 poring over the microfilm in their local library."
I said there is a major difference in scale between "modern strip mining" and "a preindustrial extraction method powered only by human muscle", and I made an analogous point about AI-enabled information extraction versus 1980s manual archival research. That statement is purely true. Nothing in that statement says the muscle-powered-extraction example was the only preindustrial mode of production, just as "someone using microfilm in 1980" does not imply microfilm was the only way information was accessed in 1980. The fact that other information formats existed in 1980 is irrelevant to the truth of the example.
So no, nothing I said "turned out to be false". You are attacking a claim I never made because you failed to parse the logic in the one I did. Most importantly, this direction missed the big picture dialectical synthesis that I was introducing as well, and just kept decomposing the argument into locally falsifiable atoms which lost the thread of what was actually being discussed.
