As I use copilot to write software, I have a hard time seeing how it'll get better than it already is. The fundamental problem of all machine learning is that the training data has to be good enough to solve the problem. So the problems I run into make sense, like:
2 and 3 could be alleviated, but probably not solved completely with more and better data or engineering changes - but obviously AI developers started by training the models on the most useful data and strategies that they think work best. 1 seems fundamentally unsolvable.
I think there could be some more advances in finding more and better use cases, but I'm a pessimist when it comes to any serious advances in the underlying technology.
Not copilot, but I run into a fourth problem:
4. The LLM gets hung up on insisting that a newer feature of the language I'm using is wrong and keeps focusing on "fixing" it, even though it has access to the newest correct specifications where the feature is explicitly defined and explained.
I've also run into this when trying to program in Rust. It just says that the newest features don't exist and keeps rolling back to an unsupported library.
Oh god yes, ran into this asking for a shell.nix file with a handful of tricky dependencies. It kept trying to do this insanely complicated temporary pull and build from git instead of just a 6 line file asking for the right packages.
"This code is giving me a return value of X instead of Y"
"Ah the reason you're having trouble is because you initialized this list with brackets instead of
new().""How would a syntax error give me an incorrect return"
"You're right, thanks for correcting me!"
"Ok so like... The problem though."
Yeah, once you have to question its answer, it's all over. It got stuck and gave you the next best answer in it's weights which was absolutely wrong.
You can always restart the convo, re-insert the code and say what's wrong in a slightly different way and hope the random noise generator leads it down a better path :)
I'm doing some stuff with translation now, and I'm finding you can restart the session, run the same prompt and get better or worse versions of a translation. After a few runs, you can take all the output and ask it to rank each translation on correctness and critique them. I'm still not completely happy with the output, but it does seem that sometime if you MUST get AI to answer the question, there can be value in making it answer it across more than one session.
