Yeah this is the really big one - kind of buried the lede a little there :)
Understanding product and business requirements traditionally means communicating (either via docs and specs or directly with humans) with a bunch of people. One of the differences between a junior and senior is being able to read between the lines of a github or jira issue and know that more information needs to be teased out from… somewhere (most likely someone).
I’ve noticed that when working with AI lately I often explicitly tell them “if you need more information or context ask me before writing code”, or variations thereof. Because LLMs, like less experienced engineers, tend to think the only task is to start writing code immediately.
It will get solved though, there’s no magic in it, and LLMs are well equipped by design to communicate!
