This is how the future arrived. It began innocuously, in the early 2000s, when businesses started to realize that highly skilled jobs formerly performed in-house, by a single employee, could more efficiently be crowd-sourced to a larger group of people via the Internet. Initially, we crowd-sourced the design of T‑shirts (Threadless.com) and the writing of encyclopedias (Wikipedia.com), but before long the trend started making inroads into the harder sciences. Pretty soon, the hunt for extraterrestrial life, the development of self-driving cars, and the folding of enzymes into novel proteins were being done this way. With the fundamental tools of genetic manipulation—tools that had cost millions of dollars not 10 years earlier—dropping precipitously in price, the crowd-sourced design of biological agents was just the next logical step.
