The difference here is that I know as well as everyone else that I couldn't possibly do what the excavator does with my own two hands, so the skill here becomes operating the vehicle itself. But what the LLM can do, I can do.
This is so often the argument when talking to LLM apologists/proponents, that "this is a shift just like any other before it", but it isn't. It sneakily resembles one, but it is not exactly like one. There are major differences that set it apart from previous shifts. This isn't just a "paradigm shift". We are no longer thinking of solutions on our own, so we are/will be losing the ability to do so, yet we are expected to be the judges as to whether the generated solutions are good or not. That doesn't add up.
Once a few generations of "developers" have grown up with LLMs, it'll eventually be like using a calculator to solve divisions with large numbers, yet still you have to check your work. But if you keep using the calculator, or you never even trained yourself to do the divisions by hand in the first place, you won't be able to check the solution is correct.
