Very weird example to me, with the LLM chatbot video. Like, yeah, interacting with an LLM can be interesting, but you're not going to learn anything meaningful about it.
And when I jumped into the middle of the video, that looked pretty much exactly as I expected, too. The guy was tweaking the pre-query and then chatting with the chatbot to see how it turned out. So, they didn't do/learn much coding either.
There is all that surrounding technology, which you are inevitably going to learn something about, but ultimately this is what I find so tiring about LLMs. I can learn something about the surrounding technology and tackle a topic which is meaningfully interesting at the same time. Unless I had a problem which a custom adaptation of an LLM could solve, why would I choose to play with it?
