Yes. Audio, video encoders, decoders etc, 3D modeling, rendering etc.

That too is "domain" even it feels like it is NOT. Domain of signal processing, Euclidian spaces, information theory and what not. Thar too is all "domain" and that "domain" part is difficult to write.

Then what do you mean by pure software? I think there's essentially zero domain-free software.

It is kind of funny though how all this hand wringing on performance, graphics, quality quality quality, has just resulted in basically same stuff as what I was doing with my computer in 2000 but with enormous resource use in comparison. Still playing games, still same old discussion forums/social media/whatever on the internet, same email and office suite, same chat, same media players, same everything. I can't even see the difference between 1080p and 4k from a couch, and people are trying to sell me 8k to watch the same stuff.

It just does not matter. The ideas matter. Novel functionality matters. But that isn't what any of that is. Same old. And the effort spent, the resources, the energy. All for more polygons on Lara Croft.

You do realize that all the domains you used in your example are trivial for an LLM to write?
