Tom -
I think you are on to something big. You've hit on a theory of the evolution of gca that explains (almost) everything.
Marx had his dialectical materialism. Now we've got the alcoholic, bloviating curmudgeon theory. We'll call it the ABC Theory for short.
The ABC Theory states that if you are/were an architect and you aren't/weren't an alcoholic, bloviating curmudgeon, you weren't very good.
The facts speak for themselves. On the ABC side we have CBM, Flynn, MacK, Tillie, Behr, and Dick Wilson.
On the non-ABC side we have nice, respectable family guys like Fazio, Arthur Hills, Robinson, Nicklaus, Byrd, Maxwell and Cobb.
In short, if you aren't an ABC type, odds are you aren't a very good architect.
I rest my case.
Bob
