Would it really become a bottleneck ? Only if we force a human in the loop when it may not be really necessary.

If there are well defined contracts for the software, and the software behaves correctly, is it really necessary for understanding the code entirely ? We seem to develop on many abstractions already ignoring how the code actually executes on the hardware without any issues.

Secondly, wouldn't AI help in understanding the codebase and make that easier as well ? Debugging must also immensely benefit from AI assisted tools.

So i'm less concerned overall with the auto-generated code as long as the code thats landing is reviewed by an AI bot that's aggressively prompting to ensure the code is as simple as it could be.
