AI is quite good at writing small sections of code. Usually because it's more or less just copying something off the internet that it's found, maybe changing a few bits around, but essentially just regurgitating something that's in its data set. I could of course just have done that but it saves time since the AI can find the relevant piece of code to copy and modify more or less instantly.

But it falls apart if you ask it to build entire applications. You can barely even get it to write pong without a lot of tinkering around after the fact which rather defeats the point really.

It also doesn't deal well if the thing you're trying to program for is not very well documented, which would include things like drivers, which presumably is their bread and butter.
