Yep this is especially true in the pre-product-market-fit phase. Most if not all of that code should be written to be thrown away. Any time you spend writing perfect code instead of your MVP is burnt runway and a chance for competitors to catch up.

Once you show PMF though the balance changes to long-term sustainability and maintainability.

What's going to be interesting is getting to a place where it generates better code than we would from specs. You can get better and better generated code by filling in the context the model infers. Do that long enough, and well, a perfect spec is just code.

We do live in interesting times.
