No, that was my point. You were trying to say that it's OK because it correct itself over time. However, that fact does not really help us in the present time.
You seem to imply that science causes people to make mistakes. The opposite is true: people make mistakes and generate stupid ideas with reckless abandon. Science is the process of putting those ideas to objective scrutiny, and validating or refuting them with evidence. Stupid doctors came up with the idea of a lobotomy, science refuted it as a bad idea. You blame science for the origin of the idea, which is missing the point.
Your entire arguments rests on a "No true Scotsman"-like logical fallacy.
