> what we do now looks nothing like what those of us who were around then were doing
20 years ago I learned some Objective-C. That's still fairly relevant. I recently used an obscure bit of Foundation knowledge no one else around me knew, so to some extent it was even valuable.
Design patterns from 20 years ago may be looking a little long in the tooth, but if you learned the principles as well as the pattern (i.e. what matters most is separation of concerns) that still serves you well today.
