alt Hacker NewsWell, humans developed language. Language is just a tool that let's us leverage our innate intelligence.
I'm sure that we will eventually build artificial brains, capable of bootstrapping communications and language for themelves (if run en-masse in a simulation where the benefit of communication would emerge). An LLM can't do this since it is by definition/construction something only capable of learning a pre-existing language.
An artificial brain, just like a wet jiggly one, is always going to be more intelligent than a one-trick pony like an LLM - a language processor, but it is notable how intelligent that one-trick pony nonetheless appears to be.
I think it's interesting that you think we could bootstrap an artificial brain with no inputs from human culture. I disagree, but am open to an existence proof of this kind. Such an artificial brain would be totally alien to us, of course. I wonder how differently it would perform versus something more grounded in "real" culture and writing?
