The complexity of code is combinatorial. Code is harder to understand than it is to create. The LLMs will be creating code that they will not (nor will any human) be able to understand later, or it won't be the same understanding that was used to create it. We'll find that systems that were created with LLM code will be impossible for LLMs to contextualize, or will be cost-prohibitive to do so.
