@leaverou from the experience of the person doing the inputting, there's probably very little difference, especially if you don't look at the generated or compiled code and just check the end result.
I do find it interesting and I'm not here to fight - as I've had this train of thought too (though you've obvs done the research).
From the energy use and IP theft side of things, very different, though. I actively feel some guilt when I go ahead and use an LLM.
