Simplicity is the hallmark of truth— we should know better, but complexity continues to have a morbid attraction. When you give for an academic audience a lecture that is crystal clear from alpha to omega, your audience feels cheated and leaves the lecture hall commenting to each other: “That was rather trivial, wasn’t it? The sore truth is that complexity sells better.
If in physics there's something you don't understand, you can always hide behind the uncharted depths of nature. You can always blame God. You didn't make it so complex yourself. But if your program doesn't work, there is no one to hide behind. You cannot hide behind an obstinate nature. If it doesn't work, you've messed up.
Don't blame me for the fact that competent programming, as I view it as an intellectual possibility, will be too difficult for 'the average programmer', you must not fall into the trap of rejecting a surgical technique because it is beyond the capabilities of the barber in his shop around the corner.
