Just an honest question, but did anyone actually define minimalism before it dies, so we can have a proper eulogy?
I noticed a few years back that Gil and a few other architects started hedging their bets on at least the historic preservation aspects of minimalism, saying things like "balancing the past and future" to cover their design ideology, which was different than some earlier arguments that a course should be restored to exactly the way it was at its high point.
Building architecture had its minimalist period, which was rooted in the newer materials of steel and glass, but technology kept improving the cost effectiveness of "ornamentation" aspects and minimalism is certainly dead in buildings, at least if money isn't tight. Function may be the main way to judge a design, but ornamentation is of at least secondary importance. No one would want their house to be as spartan as a Russian prison, for example. As FLW said, "form follows function, but identity resides in ornamentation."
In golf, that might be different than structures, since nature is usually a bigger part, but the main design goal is always to give people an experience they enjoy, no matter what, over trying to employ a specific design style. If action movies and video games make us all a bit more visually oriented, it makes sense to me that going overboard visually at least by a bit may be a requirement of modern design.
IMHO, minimalism in golf was kind of the opposite, i.e. not based on what was possible but on what had historically been done with less technology. Personally, I believe the minimalism in building architecture was more "sincere." In architecture, I doubt a period where they just copied the past (i.e., greek columns, etc.) would be "utterly cryt down upon" as a very uncreative period of design, whereas in golf, we seem to think it cannot be done any better than a century ago.
And in any case, golf course design isn't much different than other aspects of modern pop culture, which is always looking to move on to "the next big thing" so it was probably time for something new to evolve, hopefully keeping the best parts of what has gone before, but tweaking them to be new and different.
