In other words, a higher-level JIT compiler, meaning it still dynamically generates code based on runtime observations, but the code is in a higher-level language than assembly, and the observations are of a higher-level context than just runtime data types.
I agree this is what the article says, but it's a pretty bad premise. That would only be the case if the primary user interaction with coding agents was "feed in requirements, get a finished product". But we all know it's a more iterative process than that.
