No one mentions the real reason, also because it is the large elephant in the corner of the room we ignore.

The truth is - most developers write crappy code. Even right now, here, on this site, plenty of people like their code is fine, it is the code of others that hurts the eyes.

We can say that programming is hard, the languages and tools maybe not perfect, but, that's not quite it. A lot of developers just want to ship it, get it compiled and out of the door. It passes some tests, so it must be done.

If we built bridges like we built software, well, we know how that ends....
