Here's one way to look at it:

One day, these chips will be gone, and designers will have to learn how to design circuits that perform the same functions using new parts. I figure that you might as well start the process of learning how to design with new parts now, rather than build a bunch of PCBs that can't be used once the chips they were designed for are not available. If you design with modern parts, your boards won't become obsolete when the old chips are gone.
