From my experience, more junior devs don't have the skills to use LLMs properly. On top of that, most people in general aren't up to date on the latest updates and will try to use free ChatGPT and form an opinion based on that. It will take some LLM education for them to be more productive, and some serious "you shouldn't use it to generate anything you couldn't write yourself" talks. But I can see the potential in the future.

I kept on top of what's happening in this space and found ways to improve my work, but I doubt the improvement crosses 10%. This place will have a skewed statistics of people who can use LLMs efficiently - outside, in real world I don't think the impact is noticeable at all yet.
