This kind of thinking only works as long as the machine can actually fix its own errors.

I've had several bugs that required manual intervention (yes, even with $YOUR_FAVORITE_MODEL -- I've tried them all at this point). After the first few sessions of deleting countless lines of pointless cruft, I quickly learned the benefits of preemptively trimming down the code by hand.

We have confidence in the extra code a compiler generates because it’s deterministic. We don’t have that in LLMs, neither those that wrote nor read the code.

But someone needs to review and maintain the computational geometry code; or edit it to use a novel algorithm/optimize it.

And even if they didn't every line of extra code without sufficient abstraction adds cognitive overload.
