It always surprises me that gender prejudice turned by 180 between 1970 and 1980. Programmer was a cheap woman job: Typist, data typist, COBOL programmer was a typical career. It was believed that men can not even type 40 years ago, when I started to become a coder. Suddenly programmer became a male job. And the code quality dropped drastically from 1 bug per 10000 lines to 1 bug per 1000 lines. hey Code had to be bug free !BEFORE! it was submitted to the compiler in a typical female team.

So the male programmer prejudice brought less quality for a higher price.
