And I would easily argue that it's harder to copy the behavior of a good software engineer than it is to copy the moves of a good chess players.

Not even talking about understanding the business logic you are actually implementing. Which LLM seems as far as understanding chess.

I can 100% see AI worsen and accelerate that kind of things.

But where real decisions need to be made by those with "skin in the game", LLMs are a disaster. Vibe coding quickly falls off a cliff. They create code architectures that no human would given the context, and as a result no human can feasibly understand or maintain them long term.

I would say this is boon to real software developers - tons of apps that need an expert to maintain, it's job security, right? Well, no. I suspect, rather than maintain these LLM-generated monstrosities, most organizations will just let them rot. That was the default in the golden age of zero-interest engineering, that's the default in the golden age of vibe coding too.
