Interesting. I learned programming on the mainframe. PCs were a ways off. Surprisingly enough. I bought a pc for my daughters when they were young and they had no interest in computers at all. But I do think it may have to do with the development platform and as the article points out, it seems to be all about the gaming.
Most young male developers want to work for gaming companies especially here in bc.
Myself and many of my female colleagues worked for financial institutions and insurance companies.
Interesting article.
