We might think that simpler code will be easier to write, but it turns out that, quite often, simpler is harder. It takes more thought. It takes more discipline. And it requires us both to let go of preconceived ideas about design, and to let go of our egos. A lot of complexity in code is accidental – we just didn’t think of a simpler way. But a lot is also deliberately created to impress, in the mistaken belief that more sophisticated code means a more sophisticated coder.
