To push back a little, I'd mentioned that outside of golf, people who like old things/quirk are readily able to say the newer versions are better while still admiring what they love about the old. Very few antique car guys would actually rather be in a Model T or '61 Continental than a new Mercedes on a cross-country car trip. In golf, we have a harder time (me included) making this type of distinction. I'm not sure why, but I notice this most in golf. I'd love to hear if someone sees it, on this large a scale among the well-informed, in areas other than golf. There are caveats as well. The bad old golf courses (cars, tools, etc.) didn't really survive...and so on, but I'm curious.
Charlie,
If function is a large part of our assessment of the object, cars and golf courses may not be a great analogy because there have been so many technological advances that have made cars perform better. You can't compare today's cars in terms of function to those from decades ago. But while there have been technological advances in building golf courses, it's still just hitting a ball across a piece of ground. So an old course can function just as well as a new one, especially because you can make tweaks to improve drainage, soften slopes that have become too steep, or many other small changes that retain the form but improve the function (I guess you could also put a new engine in an old car).
And the limitations of the past in golf course construction are probably why we have some of the quirks that I admire so much in the older courses. They couldn't bulldoze the dunes at RCD, so they did the best they could, which was to leave enough room to hit to on the other side. Site limitations like these also make it more likely that you'll have a lot of originality because every site is different and if there are some strange/challenging things that you can't avoid, you may end up creating something really great and different from it.
Or you may just create something awkward. From what I had heard, I was concerned about this with RCD. I thought that it might be too narrow and difficult, especially given the wind. I didn't think it was. But other old links courses that I like, like Perranporth or Rye, don't strike the balance between quirk and playability that RCD does, which is part of why I think that RCD is a superior course.
So as I'm sure others have said on this website many times before, not all quirk is good quirk. We still assess its function and may have different views on that. A lot of people love the unusual 4th hole on Rye, with its fairway routed along the dune ridge. I think it's too narrow, especially in a cross wind. But because they can change them, modern architects don't have to figure out how to make something of these site limitations. And while that removes some of the risk of creating something bad, it also probably reduces some of the opportunities to create something original and good. The best courses of the past stand apart in the latter.
