Jokes aside: they really seem to do some things like live captions and translations. Pretty sure you could also do these things on the iGPU or CPU at a higher power draw.

In fairness NPUs can use less hardware resources than a general purpose discrete GPU, thus better for laptop workloads, however we all know that if a discrete GPU is available, there is not a technical reason for not using it, assuming enough local memory is available.
Ah, and NPUs are yet another thing that GNU/Linux folks would have to reverse engineer as well, as on Windows/Android/Apple OSes they are exposed via OS APIs, and there is yet no industry standard for them.
