The decreasingly tangible product of code, i.e. that all we have are files on a hard-drive, may make it easy to forget that writing software produces a thing. If you produce a wonky chair or an overly long fork, it’s easy to see the quality of work was not great. By calling for a perception of software as a craft, we fight against that ability to forget or not notice the final quality of the product. You could watch two software engineers with different levels of experience, or in different domains, and it wouldn’t necessarily be so easy to guess which is which, at least from a distance.
So maybe there is something to be said for the value of software as a craft, for sometimes focusing on the practice of making better, or at least different, software just for the sake of it.
To understand what a real essay is, we have to reach back into history again, though this time not so far. To Michel de Montaigne, who in 1580 published a book of what he called "essais." He was doing something quite different from what lawyers do, and the difference is embodied in the name. Essayer is the French verb meaning "to try" and an essai is an attempt. An essay is something you write to try to figure something out.
If all you want to do is figure things out, why do you need to write anything, though? Why not just sit and think? Well, there precisely is Montaigne's great discovery. Expressing ideas helps to form them. Indeed, helps is far too weak a word. Most of what ends up in my essays I only thought of when I sat down to write them. That's why I write them.
The Meander (aka Menderes) is a river in Turkey. As you might expect, it winds all over the place. But it doesn't do this out of frivolity. The path it has discovered is the most economical route to the sea.
The river's algorithm is simple. At each step, flow down. For the essayist this translates to: flow interesting. Of all the places to go next, choose the most interesting. One can't have quite as little foresight as a river. I always know generally what I want to write about. But not the specific conclusions I want to reach; from paragraph to paragraph I let the ideas take their course.
