60 breakthroughs that relied on human participation

Behind every major scientific advancement lies countless human contributions. Some are from renowned researchers in sterile labs, others from ordinary people sharing their time, data, and experiences. While history often celebrates lone geniuses, many of our greatest discoveries were only possible through mass human participation.
From the first medical trials to modern AI training, these breakthroughs share a common thread: they required thousands, sometimes millions, of people working together. Some participants translated languages, others identified galaxies, many simply shared their daily experiences. But each contribution, however small, helped build something larger than themselves.
In no particular order, we’ve put together 60 significant breakthroughs that wouldn't exist without human participation. Sure, these are all technical achievements. But more importantly, they're testaments to humanity's collective power to advance knowledge through shared effort.
Let's explore how human collaboration changed our world for the better.
