Hi Ben
Hope you don't mind, but I am afraid that "There is a narrow line between bravery & ...."
As someone who really gets your genuine enthusiasm (one resonant of a young man writing a Golf Course Guide that was for friends only...), I would suggest a pause here...
Your OP question, which is essentially "What's next?" is absolutely valid.
Especially, as those that mimic the perceived style and presentation of the 3 GCA's you cited, with far less talent and success are diluting their ethos. Such are notable periods in design challenged over time, ubiquity and pastiche brings these periods to a close, but that is not the fault of the leaders of such movements.
It also is the great challenge they face.
Tom and the others grasp that better than anyone, hence their constant innovation/evolution/variety.
The problem is you picked on the wrong guy (and perhaps in enthusiasm too stridently, one of my traits hence my empathy here in reaching out) as Tom has shown himself to be the opposite of what you describe.
Tom's body of work stands for itself as varied and thought-leading, very few can do the range of design he has done so successfully.His mentor Pete Dye liked to turn the other way to surprise, and Tom has done the same.
I am no expert on all his work but it strikes me that Apache Stronghold is very different from The Loop and especially Sedge Valley.
Others more au fait with his work can no doubt give numerous other better examples of his "range".
From what I hear in recent podcasts Tom is about to share some pretty special work in the next few projects...I have no doubt they will all be different in some way.
Why?
Because he works with the land, and pushes boundaries (but not just for the sake of it)
But the one thrust you are really wrong on is use of technology, have you not studied his Lido project?
This is potentially the most challenging and impressive use of the very things you throw the other way, in error I am afraid.
Yes it's CBM's original design, but few could lead such a project so well to bring out the talents of his team and CBM's genius so many years on and in a different location entirely.
Someone "stuck in the past" could not have succeeded. (Note: Lido "reduxes" have been done before far less successfully)
So I'd suggest focus on the key question "What's Next?", leverage your undoubted (Building) Architectural knowledge, and show us what you can do to push the art forward.
I'm very interested to see what it might be...
Cheers!
