The slashdot headline has little to do with the actual article. There is no causality present between the use of CAD and drawing, or at least none that has been discussed in the article itself, and the association is much clearer. My design students generally suck at drawing when they begin their studies for a simple reason: they've been spending less time practicing drawing (and more time playing WoW, not necessarily using CAD).

A bigger problem that isn't mentioned is that the command for traditional drawing and sketching skills in the United States is shrinking, and growing dramatically in China. http://www.core77.com/reactor/08.04_china.asp has an interesting article about this topic, which - in my opinion - is the design equivalent to off shoring in India. Cheaper labor combined with equally (or often better) skilled employees is a no-brainer for traditional US business. Additionally, the manufacturing firms in China will often "throw in" design services for free if you tool or manufacture with them.

It's gotten to the point where the Taiwanese are off shoring to China because it's cheaper ..
