You can pick apart a nail gun and see how it exactly works pretty easily. You cant do that with LLMs. Also a nail gun doesn't get less accurate the more nails you shoot one after another, a LLM does get less accurate the more steps it goes through. Also a nail gun shoots straight and not in random directions as that would be considered dangerous. A LLM does shoot into random directions. The same prompt will often yield different results. With a nail gun you can easily pull the plug and you wont have to verify if the nail got placed correctly for an unreasonable amount of time, with LLM output you have to verify everything which takes a lot of time. If an LLM really is such a great tool for you I fear you are not verifying everything it does.
If the boilerplate is that obvious why not just have a blueprint for that and copy and paste it over using a parrot?
Also I dont have a nail gun subscription and the nail gun vendor doesnt get to see what I am doing with it.
You mention a thousand ways the analogy breaks when you take it too far, but you didn't address the actual (correct) point the analogy was making: Some people don't enjoy certain parts of the creative process, and let an LLM handle them. That's all.
