Simply, it made my last job so nightmarish that for the first time in this career I absolutely dreaded even thinking about the codebase or having to work the next day. We can argue about the principle of it all day, or you can say things like "you are just doing it wrong," but ultimately there is just the boots-on-the-ground experience of it that is going to leave the biggest impression on me, at least. Like it's just so bad to have to work alongside, either the model itself or your coworker with the best of intentions but no domain knowledge.

Its like having to forever be the most miserable detective in the world; no mystery, only clues. A method that never existed, three different types that express the same thing, the cheeky smile of your coworker who says he can turn the whole backend into using an ORM in a day because he has Cursor, the manager who signs off on this, the deranged PR the next day. This continual sense that less and less people even know whats going on anymore...

"Can you make sure we support both Mongo and postgres?"

"Can you put this React component inside this Angular app?"

"Can you setup the kubernetes with docker compose?"
