Carlyle,
You certainly have read a lot of architecture. However, you've missed Flynn, who 'hit the nail on the head' re: technology when, in 1927, he wrote:
'If, as in the past, the distance to be gotten with the ball continues to increase, it will be necessary to got to 7,500 and even 8,000 yard courses and more yards means more acres to buy, more course to construct, more fairway to maintain and more money to fork out.'
Sure, it's fun to try new equipment. But it's no fun paying $300 green fees, everywhere, which will inevitably be the case if an adequate test of golf requires 8,000 total yards or more in the near future.
No doubt, golf architects can design great courses based on players hitting 400 yard drives (although, I'm not sure short doglegs are the answer). And, perhaps, the classics will eventually be completely out-dated, for even average golfers. But those are not the most pressing problems presented by an even longer golf ball. It's the economics of the situation that's most troubling.
