My current theory is that programming is quite literally writing. The vast majority of programming is not conceptually difficult (contrary to what a lot of people would have you believe). We only make it difficult because we suck at writing. The vast majority of programmers aren’t fluent, and don’t even have a desire to be fluent. They don’t read other people’s code. They don’t recognise or use idioms. They don’t think *in the programming language*. Most code sucks because we have the fluency equivalent of 3 year olds trying to write a novel. And so our programs are needlessly complex.
Those programmers with a “spark” are programmers who have an innate talent for the language. Or they are people who have read and read and read code. Or both. We teach programming wrong. We teach it the way Japanese teachers have been teaching English. We teach about programming and expect that students will spontaneously learn to write from this collection of facts.
