Humans just don't commit the same kinds of booboos as LLMs do. My team at work recently started using LLM agents for coding and I have since seen WTFs that I know no human would ever write.

It's not all bad! It's also enormously fun. I've been able to work on things I'd been putting off forever. When I can use LLM agents, I less often feel paralyzed by perfectionism, which is probably the biggest productivity boost I get. My own code has not decreased in quality, and I think that for the truly important things, neither has that of my colleagues.

But LLMs don't make junior dev mistakes. They make "my brain has worms in it" mistakes.
