The Hidden History Written in Code

Your first computer probably wasn't remarkable-maybe a beige box with a screeching modem that transformed your bedroom into something magical. Mine certainly wasn't special by today's standards, yet it opened portals to worlds I'd never imagined. Those machines are gone now, recycled or rusting in distant landfills, but what they enabled remains: human connection across impossible distances. Here's what most technology histories won't tell you-the internet wasn't built by lone geniuses in garages. It was constructed, programmed, and imagined into existence by women whose names you've likely never heard. From the first algorithm to the social architecture of online communities, women have been there at every technological revolution, often doing work nobody valued until suddenly everyone did. For nearly two centuries, "computer" wasn't a machine-it was a job title. Classified ads sought human computers to perform complex calculations, charting stars and solving equations in intellectual factories. By the mid-twentieth century, this work became so associated with women that mathematicians measured machine power in "girl-years" and "kilogirls." The connection between textiles and computing runs deeper than metaphor. Joseph-Marie Jacquard's revolutionary loom used punched cards to weave intricate patterns, separating design from execution for the first time. Charles Babbage, inspired by a silk portrait of Jacquard woven using 24,000 punched cards, adopted textile language for his computing machines-"store" and "mill" became memory and processor.
