I'm finding myself using the extensively in the learning way, but also I'm an extreme generalist. I've learned so many languages over 23 years, but remembering the ones I don't use frequently is hard. The LLMs become the ultimate memory aid. I know that I can do something in a given language, and will recognised that it's correct when I see it.
Together with increasingly powerful speech to text I find myself talking to the computer more and more.
There are flaws, there are weaknesses, and a bubble, but any dev that can't find any benefit in LLMs is just not looking.
