Architecture should have little to do with problem solving - rather it should create desirable conditions and opportunities hitherto thought impossible.
Technology is the answer, but what was the question?
Like medicine (architecture) must move from the curative to the preventive.
Architecture is too slow in its realisation to be a 'problem solver'.
Architecture must concern itself continually with the socially beneficial distortion of the environment.
Likewise 'radical'. I'm only radical because the architectural profession has got lost. Architects are such a dull lot - and they're so convinced that they matter.
