A computer is only a tool, just like a calculator, slide rule, handbook, template, or phone, but it can be a very powerful tool. The decline of engineering in understanding the laws of nature has displayed itself in the disposable products that we buy. Just because it can be drawn with CAD doesn't mean that it will work. Nor does it guarantee that it makes sense. Engineering education, experience, and judgment are necessary for that.
Bad decisions equal bad designs.
In the long run, I fear that this ability will push down priorities regarding real-world situations about how to establish educational processes that encourage creative thought and problem solving. During rush projects, however, I rely on my brain and drawing skills to outline, define, and propose solutions to a problem.
