So the AI doesn't actually understand the code does it? It only looks for similar things. So if I'm writing a game in Rust using the hecs ECS library, how is it going to help me? How many other people have written a game in that language using that library in this genre trying to do this task before? Probably very very few.

And yeah that's a niche example, maybe this is super helpful for writing a react app or something very library heavy. But gut feeling without trying it is that there's no way this could actually work on anything but the most common tasks that you can google and find solutions for already, just made easier so you don't actually have to google for it.

When I used tabnine which learned from you as you edit, it was fairly helpful for very repetitive code within the same project. But it was no where near "read english and write the code I meant for it". I'm curious to know how well this actually performs for non-common tasks, and whether it can understand ideas in your codebase that you come up with. If I make a WorldAbstractionOverEntities thing in my code, and then later use it in the project, will the AI be able to help me out? Or is it going to go "sorry, no one on github has used this thing you came up with an hour ago, I can't help you". An AI that could understand your own codebase and the abstractions you make and not just popular libraries would be infinitely more useful imo.

That said, I haven't tried this, maybe it'll turn out really good.
