I have not found LLMs to be most beneficial in straight writing code especially in complex large scale systems. However, I have found them extremely useful at the aspects the author claims they make more difficult: understanding, testing, and trusting that code. An LLM is an extremely useful search engine. Given access to plenty of CLI tools asking it questions about an unfamiliar code base is extremely helpful. It can read and summarize much faster than I can. I don't trust its exact understanding but I do trust it to give me a high level understanding of an architecture, call out dependencies, summarize APIs, and give me an idea of what parts of the code base are new/old etc. Additionally, having LLMs write tests after setting up the rough testing structure and giving it a few examples massively decreases the amount of time it takes to prove my understanding of the code through the tests thereby increasing my confidence/trust in it.
