This was my initial reaction as well. I have been thoroughly invested in the craft of software engineering for 3+ decades. From the blog posts mentioned in the all the way back to Byte magazine at the library as a 10 year old. But those days appear to be perhaps behind us now, as suggested in the article. I am grieving it, despite the fact I have embraced LLMs for creating software.

But I refuse to use LLMs for things like making music. I like your term "purely human". There's no place for fancy statistical engines in human art. Art belongs to human communities and human culture. Which is where, apparently, I will continue to find my refuge if not my living.
