Here is an easy example:

Say you and I both wrote the same spec that under-specifies the same parts. But we both expect different behavior, and trust that LLM will make the _reasonable_ choices. Hint: “The choice that I would have made.”

Btw, by definition, when we under-specify we leave some decisions to the LLM unknowingly.

And absent our looks or age as input, the LLM will make some _reasonable_ choices based on our spec. But will those choices be closer to yours or mine? Assuming it won’t be neither.

And I'll say it doesn't matter. If it goes with your approach then I'll say that the approach works too. And if goes with my approach I hope you would recognize that my approach also is good enough for what we need. As long as the software meets the requirements, its okay if it isn't implemented the exact way it would have been if it was done by hand.
