Change can be extremely slow and surprisingly resilient. This of course can be a good or bad or indifferent thing. Apparently, the extinction of dinosaurs was due largely on their inability to change in time.
Take car design for instance. Consumer expectations on one hand and tough laws and regulations on the other have kept the car not that much different in the last 50-60 years. Practically all have ‘eyes’ (headlights) and ‘mouth’ (grille) even when new lighting and air intake technologies are available. They all have license plates, usually unceremoniously screwed into the bodywork. (I once saw the license plate of a Royce Royce fastened with a pair of rusting screws like those of everybody else!) . They all have wing mirrors and wind-shield wipers — the last frontier of innovation! And they all have an assortment of disks and stickers on the wind-shield for road tax, club membership, season parking, etc. All these are not about to change. At the rate we are going, they may all be still around even when cars go air borne.
What about the house? When cars go air borne, the house will likely to be still brick-n-mortar, concrete-steel-glass. Chairs will be chairs and tables will be tables. Why?
I was once on a construction site when the builders laughed at the oversized calculator that our Quantity Surveyor was using. “Surely you can afford a more compact calculator”, they said. He replied, “but my fingers are not getting smaller!”
So, why is change so tough? Perhaps because we are fundamentally conservative human; full of terrible as well as wonderful ‘flaws’. For better or worse, get over it!
