I mention this when this comes up - my personal view is that it has to do with saturation. At some point being in computers became a 'good job' once that happens a field still has its curious people, but they're not as visible as they're in a sea of people who were just looking for a steady check.

I blame the dotcom boom. Yes, the business-records jobs were always part of the field, but they didn't seem so dominant. We're all writing COBOL now.
