Consider reading/watching Rich Hickey's talk Effective Programs [0][1] and Maybe Not [2][3] In [0] in particular there're slides 22/23, here is part of the transcript but makes more sense with the slides on: > And you can call them problems, and I'm going to call them the problems of programming. And I've ordered them here [...] I've ordered them here in terms of severity. And severity manifests itself in a couple of ways. Most important, cost. What's the cost of getting this wrong? At the very top you have the domain complexity, about which you could do nothing. This is just the world. It's as complex as it is. > > But the very next level is the where we start programming, right? We look at the world and say, "I've got an idea about how this is and how it's supposed to be and how, you know, my program can be effective about addressing it". And the problem is, if you don't have a good idea about how the world is, or you can't map that well to a solution, everything downstream from that is going to fail. There's no surviving this misconception problem. And the cost of dealing with misconceptions is incredibly high. > >So this is 10x, a full order of magnitude reduction in (?) severity before we get to the set of problems I think are more in the domain of what programming languages can help with, right? And because you can read these they'll all going to come up in a second as I go through each one on some slide so I'm not going to read them all out right now. But importantly there's another break where we get to trivialisms of problems in programming. Like typos and just being inconsistent, like, you thought you're going to have a list of strings and you put a number in there. That happens, you know, people make those kinds of mistakes, they're pretty inexpensive.
