I think it's just the context in which it's working in.

1m lines of html are infinitely more conducive for a language model to work in than 10k lines of complex multithreaded low level code.

A lot of coding is just rehashing the same concepts in slightly novel ways, language models work great in this context as code gen machines.

The hope is that we can focus our efforts on harder problems, using language models as a tool to make us more productive and more powerful, and with the advancements open weight models have made, also less reliant on big tech companies to do so.
