I don't know. We invented machines that can answer arbitrary questions and are quickly demonstrating the ability to answer questions no human has been able to answer. We're sending more rockets to space in a week than we have in the prior decade. My car can drive itself. We experienced a global pandemic and within six months engineered and scaled the mass production of a vaccine to mitigate it. We also just invented a weekly shot that nearly cures the most common cause of non-natural death. All of these things are new in the past ~five years. There is no definition you can invent that does not classify the times we are living in, right now, as the most impactful ever, in human history.
