alt Hacker NewsWe actually understand AI quite well. It embeds questions and answers in a high dimensional space. Sometimes you get lucky and it splices together a good answer to a math problem that no one’s seriously looked at in 20 years. Other times it starts talking about Goblins when you ask it about math.
Comparing it to an alien intelligence is ridiculous. McKenna was right that things would get weird. I believe he compared it to a carnival circus. Well that’s exactly what we got.

I think this is a case of that mildly apocryphal Richard Feynman quote: "if you think you understand quantum mechanics, you don't understand quantum mechanics."
I understand LLM architecture internals just fine. I can write you the attention mechanism on a whiteboard from memory. That doesn't mean I understand the emergent behaviors within SoTA LLMs at all. Go talk to a mechanistic interpretability researcher at Anthropic and you'll find they won't claim to understand it either, although we've all learned a lot over the last few years.
Consider this: the math and architecture in the latest generation of LLMs (certainly the open weights ones, almost certainly the closed ones too) is not that different from GPT-2, which came out in 2019. The attention mechanism is the same. The general principle is the same: project tokens up into embedding space, pass through a bunch of layers of attention + feedforward, project down again, sample. (Sure, there's some new tricks bolted on: RoPE, MoE, but they don't change the architecture all that much.) But, and here's the crux - if you'd told me in 2019 that an LLM in 2026 would have the capabilities that Opus 4.7 or GPT 5.5 have now (in math, coding, etc), I would not have believed you. That is emergent behavior ("grown, not made", as the saying is) coming out of scaling up, larger datasets, and especially new RL and RLVR training methods. If you understand it, you should publish a paper in Nature right now, because nobody else really does.
We understand the low level math quite well. We do not understand the source of emergent behavior.
Hey, about that high dimensional space, is it continuous or discrete?
Also, I'm curious what you mean by "embed", the word implies a topographical mapping from "words" to some "high dimensional space". What are the topographical properties of words which are relevant for the task, and does the mapping preserve these?
circling back to the first point, are words continuous or discrete? is the space of all words differentiatable?
