Many think without CAD, we would still have all the stuff we do today and noting world have change. A world without CAD, well lets think about this. With CAD we can design different things without wasting that much money. We can test and change everything about the design. And its way quicker then building the whole thing and then wasting tons of time and money.
So without, we would use tons of money and we would waste tons of material. The prices of different objects like cars and controls would cost a LOT of money. Mostly because of how much time it took to build it. And we wouldn't learn how may objects would work.
So we are actually lucky that CAD is real and is used around the world. We wouldn't have any Xbox 1 or anything like that in years.
