But actually theory is very practical. Gravity is a theory, for example. It allows you to predict that if you step off a cliff you will fall; you don't have to collect data on that.
The world is super-stupid. You have by far the best designers in America! And you do the most stupid cars in the world! They put billions into their stupid designs for General Motors, Chrysler, Buick, or who knows what. The designers in America must be frustrated. I am not frustrated, because I am not a designer - I am a philosopher, and all philosophers have said for ages that the world around them is stupid.
