At the end of the 18th century, the British Royal Astronomers distributed spreadsheets by mail, asking the crowd to help them create maps of the stars and the seas. In the United States during the 1930s, when the government employed hundreds of “human computers” to work on the WPA and the Manhattan Project. 3

However, as the volume of data online grew, it became clear to companies like Amazon and Google that there were some things humans were simply better at doing than machines.4
