You reminded me of this recent post, which I found very interesting: Why jet engines aren't made in China https://news.ycombinator.com/item?id=48740971 https://news.ycombinator.com/item?id=48740971 That's a very interesting point of comparison though. I wonder why that should be the case? Why is it so much harder to make a jet engine than a language model? Maybe with LLMs the iteration times are lower? Or there's more public information about technique? Or are jet engines just intrinsically a harder problem?
