They missed the innovation that has and will change the world more than any of the listed ones.
The Birth Control Pill.
I has already started a massive demographic crash across the entire world that will depopulate the world, changed the relationship between the sexes in unknown and bizarre directions, and forever altered politics by altering marriage and separating recreational sex from reproduction. Mankind evolved in a world where sex and reproduction were linked. Our physical differences, chemical differences, and emotional differences are tied to those millions of years of evolution.
The world will still be adapting to the changes fomented by the pill centuries from now.
Maybe not a great invention. But the one that has changed things forever.
That was # 20. A real disaster for humanity.
True re birth control pill.
However those of us who resist it (I don’t oppose all contraception but believe that to be abortifacient and also bad for women hormonally) should thrive.
