I think there's an element of pridefulness too, in having the ability to manage dense and intricate stuff at all. They're very smart, and it makes them feel good to be able exercise that and juggle and retain so much context at once. And they don't realize how fragile that juggling is, that it's going to take a ton of effort for them or other people to come back to it.

I think this is more prevalent for some languages/stacks than others, too; there's definitely a cultural aspect fostered the language owners or whoever the leaders are.
