Does that mean software can also be afraid, or angry?

If it is programmed/trained that way, sure. I recommend having a listen to Geoffrey Hinton on the topic.

Saying software can be inspired is like saying a rock can feel pain.

The rock doesn’t do anything similar to pain. The LLM on the other side does a lot of things similar to inspiration. I can give the LLM a very trivial question and it will answer with a mountain of text. Did my question or the books it was trained on “inspire” the LLM to write that? Maybe, depends of course how far reaching you want to define the word. But either way, the LLM produced something by itself, that was neither a copy of my prompt nor the training data.
