From what I've seen, the increases in LLM intelligence is not that type of smart. On the contrary, the better LLMs write in a more neutral and clear tone, a bit like a Wikipedia article. Actually, Wikipedia articles are already sort-of a "distillation of the Internet" into a type of average. By having many people edit them, the individual personal quirks are smoothed out, leaving a type of average-of-humans result. This reminds me of the "average faces" project about a decade ago where they blended photos of random people together. The results were often very attractive, because it's the small flaws that make normal people unattractive. The blending of many samples smooths out the flaws, resulting in a "perfect" but ordinary face. Not some post-human face, but a perfectly human face. That's what I see LLMs doing: as smart as us, but no smarter. Great breadth certainly, but not greater depth.
