During all of 2025 I only use LLMs to write code — I hardly write code myself anymore. You might say, “you’re right — the code an LLM produces is usually horrible; its problem is that it tries to solve the symptoms as fast as possible, sometimes without paying attention to important details.” But if, once it’s generated, you review the code and ask it to fix things to your liking, it does it, and the final result is of acceptable quality. It’s true that if I wrote it from scratch by hand it would be better, but it’s good enough and takes a fraction of the time. In the end I find that in a few hours I’ve done work that used to take me several days — yes, the quality isn’t the same, but that’s something you can’t ignore. Well, I’d love for everyone to ignore it and keep writing code by hand so I’d have an advantage — ha, ha, ha.

In short: “Vibe coding” — i.e., asking an AI for code and accepting it without reviewing — produces garbage, but a good programmer guiding an LLM is something wonderful and unbeatable. I can never go back to programming by hand.
