The counter perspective is that this is not a book, it's an interactive simulation of that era. The model is trained on everything, this means it acts like a mirror of ourselves. I find it fascinating to explore the mind-space it captured.
While the post talks about big LLMs as a valuable "snapshot" of world knowledge, the same technology can be used for lossless compression: https://bellard.org/ts_zip/.
If I want to read a post, a book, a forum, I want to read exactly that, not a simulacrum built by arcane mathematical algorithms.
