And of course, once we extended lossy compression to make use of the semantic space, we started getting compression artifacts in semantic space - aka "hallucinations".
I don't know, it's not that profound of an insight. You throw away color information, the image gets blocky. You throw away frequency information, the image gets blurry. You throw away semantic information, shit stops making sense :).
Still, if someone would turn that into a blog post, I'd happily read it.
There's more to it than that. You can draw strong analogies and also discuss where the analogy suffers. For example, you can compare decreased performance with accurately recalling specific information with high-frequency attenuation in lossy codecs.
