I absolutely reject the premise that the we should only consider inventions that single-handedly revolutionize the world. A lot of these so-called incremental rounding errors add up to significant sums.
No one is saying that the last 50 years have not been good for progress, or that these discoveries do not have value.
But to claim that they amount to more progress than all of the rest of human history combined is objectively wrong, especially given the amazing advances of the 50-70 years preceding them (1900-1969), which did fundamentally revolutionize human knowledge and form the scientific advances that all subsequent progress is based on, from planes to rockets and from QM to fusion reactors today.
