    From what I understand (and I might be totally wrong), 
    Copilot is useless for dealing with codebases where 
    you often need to call internal functions

Perhaps this is the next big frontier or opportunity.

LLMs have finally gotten to the point where they are sometimes useful. And local project-level code intelligence (intellisense, static analysis, etc) has been pretty good for a while.

The first team to marry these two things is going to really have something great. A true force multiplier.

It certainly doesn't seem like it will be easy, but it also certainly doesn't seem to be impossible.
