AI to help me read docs does seem somewhat handy but I feel like if there's already documentation it's really just gonna save a couple of minutes?
I will be much more excited when AI can explain undocumented systems to me. This feels like it can't be far away, and it will be a game changer.
I guess for this to be helpful it is gonna need out-of-band info, but maybe just the git log would be a pretty good start. If you could add a mailing list or chat history of developers I imagine things could get more powerful.
