No, this is not a pre-existing problem.

In the past the problem was about transferring a mental model from one developer to the other. This applied even when people copy-pasted poorly understood chunks of example code from StackOverflow. There was specific intent and some sort of idea of why this particular chunk of code should work.

With LLM-generated software there can be no underlying mental model of the code at all. None. There is nothing to transfer or infer.

It’s even worse because the solution an LLM produces is not obvious as to whether it was inherently chosen by the user and favored over a different approach for any reason, or it was just what happened to be output and “works”.

I’ve had to give feedback to some junior devs who used quite a bit of LLM created code in a PR, but didn’t stop to question if we really wanted that code to be “ours” versus using a library. It was apparent they didn’t consider alternatives and just went with what it made.
