If you want to shit talk LLMs, you better come armed with research, buddy. Claims about how it will revolutionise every profession just need n=1 anecdata though.
Historical comparison: "I just had a pizza delivered on the new Segway and it was super duper cool because they came right into the conference center, so say goodbye to cars and bikes, by 2025 it's all going to be Personal People Movers!"
That said, I think LLMs will have a bigger effect than a self-balancing scooter, both positively and negatively.
Correct, the study showed that it slows down experienced developers. We don't know what it does to inexperienced developers so that sounds like a good research topic. But it still leads to the question of why experienced developers should be told to adopt it, given that it slows them down.
