I am straining to think of another design field that says, "You can never do better than 100 years ago, so keep copying old stuff." In fact, if they did, it would probably be considered among the worst, least creative design eras of all time.
As good as FL Wright was, no one really copies him anymore. Nor do architects copy Greek or Roman temples, art deco, etc.
If the state of design in other fields is similar to what has become a mantra of gca, thanks in part to this site, they would.....but they won't. It is one thing to take a good principle that should always work as an inspiration or base, like proportionality (i.e., the "magic" 5/8 ratio, etc.) and quite another to believe that nothing you do originally has a chance of being as good so you copy what was done before.
Once in a great while as a "conversation piece," sure. But it is time to move on and create some new templates that really work for the future, not the past.
As always, just MHO.
