This reading deals with the frenzied , naïve enthusiasm of a powerful new toy. Anyone who has been limited, and in their mind held back, by a short list of stilted visualization media, naively longing for a pure and vivid representation laid easily in front of them, of precisely what they desire, will easily, and with my sympathies, fall into this trap. A nearly infinite (by a human’s computational standards) opportunity for speed and processing power allow the nearly real to fall effortlessly into our laps. The anxious excitement of human achievement and this fresh, new ability, blinds us: we’ve been making good buildings for centuries without a MacBook Pro.
We’d be fools to scrap these new tools in favor of the older methods of plans, sections, diagrams, physical models, etc. A tool isn’t an end in itself; it is a means. Ultimate and instant power of computing can take us far, but only if one pays attention to the overall goal.
To take a few paces back, visualization is a method of outsourcing our concepts. That is the crux of the matter. Think of a juggler: only so many things can be up in the air, or else the flaming chainsaws he’s jugging rip him to shreds. Abstraction and visualization are a means to convert the conceptual to perceptual. One can see the papers and the table and the floor in front of them without thought, in the same way they can conceptualize the these very mundane objects easily if they close their eyes and think of them. But perception allows us to make a jump: the juggler can put some of the chainsaws on the ground so he doesn’t get wrecked, to juggle them later perhaps, or to even allow himself to imagine juggling them. (no jugglers were harmed in the writing of this paper)
Outsourcing concepts to raw perceptions doesn’t at all imply the representations need to mimic reality. On the contrary, concepts aren’t reality, they’re a truthful abstraction of the real. This is a very important point. Laws governing existence and order can be distilled and refined to useful concepts, which can be later represented in an unrealistic, but perceptually bountiful way.
