> Half of it are "discoveries" which were lost or disregarded and had to be "re-discovered", and IMO those are not discoveries at all since they change or affect nothing. Surely the relevant consideration should be how much the discovery affected people at the time, not whether the discovery was eventually lost and needed to be re-discovered. Consider that all discoveries we have made could eventually be lost. It certainly doesn't diminish the historical significance of the discovery of penicillin if that discovery is lost in the population bottleneck caused by the 2095 A.I. War and only re-discovered 100 years after that.
