I have had the opposite experience. Many domains where it can’t produce correct code (counting BitSet, WatchOS apps), or doesn’t even begin to understand (distributed consensus).

When it works it is great. When it doesn’t gap can be large.

When you ask it to correct itself it will make new mistakes and keep alternating between different mistakes and omissions.

I haven’t tried it yet on a real codebase like say a database. Is it even possible to give it that context?
