I disagree with Tom D.
Mathematically, it is much more likely that far better golf courses can be drawn than can be built. For many more ideas can be drawn than can possibly be built. Of course, we will never have the opportunity to find out which of the drawings are worthy as it takes much longer to build a course than to sketch a concept for one. (So, in reality, I do not disagree.)
The convergence of sketching (design) with construction technology is exciting. Does it replace hard work in the dirt? No, of course not. We used GPS links on The Links at las Palomas and it was interesting, frustrating and exciting — all at once. Did it make for a better golf course? Probably not. But one must consider that we did this with a first-generation compurter of sorts — the exciting era is yet to come.
As Saul Bass, a great design professional once pointed out, "The invention of the typewriter did not necessarily make for better poetry."
