As a software developer I constantly find myself optimizing and scaling across CPU's. Sure those programs I optimized 10 years ago run blazingly fast now. But as computers got faster the possibilities and expectations also increased.

I would like to compare CPU's with roads: Roads increase traffic, not the other way around. So if you make a faster CPU, the demand for a faster CPU increases.

So if Intel stops making faster CPU's, the demand will (unexpectedly) go down.
