How is that in any way equivalent to your claim, which just so we're clear, is that now 50% of the population (and implied even near 100%) now has the intellectual standards that only 3% of the population had a mere 20 years ago ?

One reason for ever improving records is that we just further explore the long tail of human performance. A decent number of factors that get this one event going would be coincidences, and because we keep and keep and keep trying people get ever closer to perfect.
