“As computers gained new status and exploded in popularity, hacker conferences and computer clubs sprang up across the San Francisco Bay Area, and enrollment in computer science classes surged at universities across the country. Demand became so great that some departments began turning students away. There was an overall peak in bachelor’s degrees awarded in computer science in the mid-1980s, and a peak in the percentage of women receiving those degrees at nearly 40 percent. And then there was a steep decline in both. It wasn’t that students were inexplicably abandoning this exciting field. It was that universities couldn’t attract enough faculty to meet growing demand. They increased class size and retrained teachers—even brought in staff from other departments—but when that wasn’t enough, they started restricting admission to students based on grades. At Berkeley, only students with a 4.0 GPA were allowed to major in electrical engineering and computer science. Across the country, the number of degrees granted started to fall.”
