When I was a $4 per hour construction intern at Long Cove, I was driving Mr. Dye out to the other end of the site one morning and I asked him about Harbour Town and how different it was than his other work, especially the Radrick Farms course that he'd done a few years before, which looked more like a Jones course to me.
Pete replied that he had looked up to Mr. Jones' work when he started out on his own, but he'd been experimenting with other stuff, and then when he was working at Harbour Town, he had to drive past Palmetto Dunes every morning and he just made up his mind that somebody had to go in a different direction, because they all couldn't keep making things longer and bigger ad infinitum.
I don't know how or why he happened to share that story with me at that time -- I was 20 and certainly not on the radar as someone who would make it on his own in the business. But, when I did, I knew that I wouldn't make a name for myself by trying to build Pete Dye style courses, and that conversation was what led me to do something different myself -- even if it had some historical precedent.
Was Mr. Jones the same? Perhaps, but I think there is also a lot of truth to the idea that he was trying to turn golf architecture into a business that was repeatable and therefore scalable to greater size. It was not lost on him that most of the competition in the postwar business was either gone or slowing down, and that he had a chance to dominate the profession like nobody in the twenties could have. He adopted technology to do so, both because he had seen the beginnings of it in the 1930's, and to prevent somebody else from coming along and rendering him obsolete.
At the same time, I don't think Mr. Jones was all about the "clean lines" you see on his courses today. Yes, he did invent the runway tee because it made maintenance easier (and addressed added length), but a lot of his courses featured very lacy-edged bunkering. In the latter case, you are just confusing the simultaneous change in golf course maintenance practices (as far as "clean" bunker edging) with Mr. Jones' style.
