An author has lived experiences, including other books they have read, to draw upon to tell a narrative they want to tell (either purely for expression, purely for profit, or more often than not somewhere between).

A machine that chews up the worlds literature and spins out a best guess at what the next word should be does not have intent, and the vast majority of the time is used by unscrupulous people purely for profit and/or deception.

An LLM and a living human being are not the same thing, I am tired of apologists comparing them as if they are.

It's not surprising that a computer (doing trillions of calculations on a billion parameter model that was trained on the world's literature) can string a coherent sentence together...
