I am happy with the LLMs, but I only tried them on small projects done at my free time.

As a back end developer I am not familiar with the latest trends in JavaScript and CSS, and frankly I do not want to spend my time studying these. A LLM can generate an interactive web game based on my description. I review the code, it is usually okay, sometimes I suggest an improvement. I could have done all of that -- but it would take me a week, and the LLM does it in seconds. So it is a difference between a hobby project done or not done.

I also tried a LLM at work, not to code, but to explain some complex topics that were new to me. Once it provided a great high-level description that was very useful. And once it provided a great explanation... which was a total lie, as I found out when I tried to do a hello-world example. I still think the 50% success rate is great, as long as you can quickly verify it.

Shortly, we need to know the strengths and the weaknesses, and use the LLMs accordingly. Too much trust will get you burned. But properly used, they can save a lot of time.
