I think you missed the article's point: yes, over the last 20 years or so tech has been an awesomely-expanding career. But it sure didn't seem that way after the dot com bust or the Eleventh of September. I was around then, and it was terrible. That tech was awesome is the article's point.

I do not see any fundamental reason why tech will not continue to be an awesome career field. Software is still eating the world. Yeah, the economy is suffering right now. It will recover.
