To the extent it’s measurable, LLMs are becoming more creative as the models improve. I think it’s a bold statement to say they’ll NEVER be creative. Once again, we’ll have to see. Creativity very well could be emergent from training on large datasets. But also it might not be. I recommend not speaking in such absolutes about a technology that is improving every day.

Most software engineering jobs aren't about creativity, but about putting some requirements stated in a slightly vague fashion, and actualizing it for the stakeholder to view and review (and adjust as needed).

The areas for which creativity is required are likely related to digital media software (like SFX in movies, games, and perhaps very innovative software). In these areas, surely the software developer working there will have the creativity required.
