Archie,
I'm sure most have. In each generation, there was only 1-2 pioneers at most, the rest were followers.
Even though I entered ASGCA the most traditional way, I doubt that had a lot of influence, given all the walks of life our members have come from. I do agree, having quit on my 29th birthday and to move to Texas on my own, that it helps to be young and naïve enough to live by the phrase, "What could possibly go wrong?" But, that is to start a business. All along the way, people will tell you your dream is stupid, unlikely to be achieved, etc. I always guessed the first test of whether you are qualified to be a gca is to not be talked out of it by well meaning parents, professors, friends, spouses, etc.
But going back to actual design out of the box thinking, I agree most of us basically want to replicate what our mentors did, make a living, etc. We want to do some cool work when given a chance and site, but again I ask, how many really set out to change the biz?
And, I recall Mac, I think, writing that there is difference between excited and different design. Stone Harbor and others that specifically seek to break the box in an "artificial" way (i.e., let's put shock value visuals over playability) probably don't do as great a job as a design that evolves from unique circumstances, i.e., form follows function in very unusual situations. Or, necessity is the mother of invention and so forth.
So, what was the greatest out of box architecture? Probably moving it from seashore inland, or maybe from GBI to the vast climate differences in the US, maybe in tropical areas like India, Asia, etc. which required quite a bit of innovation. Just a guess.
I remember Geoff Cornish's book saying just how radical the dogleg was when first introduced, perhaps another good guess at innovative thinking, and probably conceived when a large land form had to be skirted.
