What I mean is that as an industry, we're in the stone ages. What we're doing will be looked back upon the same way that look back at bloodletting that was practiced by doctors a few hundred years ago.

Just when I think I'm beginning to get a grip on things, a whole new layer opens up, and I start over as a beginner again. I've heard anecdotal evidence that programmers who have been around 30 or 40 years still experience this.

EDIT: Not to be all self-promotey, just more of a "I agree with you so much I wrote about it."
