@julkaIf there's a TLDR, it's that the first half of this is philosophically interesting but not really related to the core of the discussion (and that's probably my fault - this entire topic is 'philosophical', in the end).
I fundamentally disagree with you on this one, I don't think the act of painting or composing or whatever is a computational one; I think it can be mimicked by computation, but mimicry isn't the same thing. Your position is unconvincing to me, but I also understand that mine is similarly unconvincing to you.
The problem here is that I don't understand what else it could be. What else is there? The soul? I'm certainly willing to entertain the idea of one. I've allowed for random variation (muscles, etc). Outside of that, if the brain is doing it, it's either 'computation' or something supernatural.
Basically, what I'm saying is that the human brain (the whole thing, to the extent that we understand it right now) does not exceed the power of a Turing machine. Or, rather, we know of nothing the human brain does that a Turing machine cannot do, nor do we have a model for any form of 'intelligence' beyond the powers of a Turing machine. There are things Turing machines cannot determine; humans can't, either.
Barring the supernatural - which, again, is entirely a possibility, but unproven - that's where we are, to me. But I'm willing to envision something else. I just don't know what it could be, and I'm genuinely curious about what you think it might be.
Mind you, I weakly believe in 'the supernatural', but not in a way that affects human cognitition in any major way, barring the problem of 'free will.' If free will is primarily non-physical (which is a valid argument), then perhaps there is something that requires either humanity or biology to have 'free will.' But I don't know of a way to prove that (obviously, because - if anyone did - it would be an enormous philosophical bombshell) and, for now, I'm quite comfortable assuming 'free will' does not require biology.
A human is absolutely painting every pixel in photoshop, though?
No, absolutely not. I'm a terrible painter and visual artist. I've made some decent work in Photoshop. Had I had to paint even every hundredth pixel, it would have been total garbage. Photoshop can (and often does) take general directions ('blur here', 'feather the edges here', 'fill this') and make an enormous amount of decisions under the covers to implement them. It's reasonably analogous to what you're calling 'gaps' in fiction, at least in my opinion. It's not 'the plot', it's the stuff around the plot.
Even if that were true, though, it misses the point of the analogy (in my opinion). The point is people dismissing the work out of hand because of the tool used to produce that work, and (often) denigrating the creator of the work for being 'uncaring' and lacking 'effort' along the way. It happened with pictures when Photoshop came out, and it's happening now in words as LLMs come out. As far as I'm concerned, it's just a form of the genetic fallacy (which is highly analogous to the ad hominem fallacy - which also turns up a lot in this sort of argument).
When somebody launders their story idea through an LLM, they get something back that bears some level of similarity to the story they had in their mind, but necessarily it's not the story they had in their mind, because it's gone through the step of being translated by the LLM. They have decided that they are willing to accept the LLM's translation choices, and I view that as not caring about those choices.
Certainly, I can see this as a reasonable argument, up to your last sentence. I don't see why 'I'm willing to let translator X make choices in translating my work' is equivalent to 'I don't care about those choices.'
Stanislaw Lem is a pretty acclaimed science fiction author. Unfortunately, I don't read Polish, so I've read English versions of many of his works. He agreed to have his works translated. Does that mean he didn't care about the resulting work? Obviously not - Lem worked very closely with his translators over decades.
But Lem's work is also necessarily different in English than in Polish in many places. He uses wordplay that can't be translated, so his translators - who were likely brilliant themselves - changed the story to analogous but different wordplay. While Lem himself believed it was fundamentally impossible for the translations to be exactly what he intended, he nevertheless approved the translations once they met his standard.
I'm just not sure why 'I used a translator' means 'I don't care about the work.' And, in this case, a 'lousy English' to 'good English' translation leaves the original author fully capable of accepting or rejecting the translation. Is it a good translation? Then it's good. Is it lousy? Then you have a case that the author doesn't care.
But, again, you're back to actually needing to judge the resulting work, not rejecting it out of hand because someone failed to use effort, or care, or whatever, as evidenced simply by the choice of tools they used and not any charactistic of the resulting work itself.
Back to the Photoshop analogy. Your arguments seem to consistently boil down to 'But they used this particular tool I don't like! Anyone who uses that tool doesn't care about the work and isn't putting in the effort!' And that is the genetic fallacy, pure and simple.
And part of this is necessarily philosophical. If one's view of 'an author' is a person who chooses each word themself with no help, no use of tools will help.
I don't know what you mean by this. There are plenty of tools that help authors choose all the words and put them in the right order while still philosophically remaining "authors" in my mind.
There are people out there who say 'You used a tool!' or 'You had an editor/proofreader/advance reader!' and argue that that makes the work itself essentially 'impure' and no longer the 'author' but, to whatever extent, a co-author. I've seen it on here before. Nothing but the author pecking each key themselves is allowed. It wasn't really important in the grand scheme of things.
I'm certainly not accusing you of doing that. You're just doing that with tools you don't like. You're entirely welcome to do that, but be clear about it. In other words: 'You used this tool. I don't like this tool. Therefore, I don't like the work you produced.' Had you said that, I wouldn't have bothered to reply, because that's a straightforward and defensible position. I don't agree with regard to this tool, but it wouldn't worth responding to.
On the other hand, failing to say that, but instead making it about 'effort' or 'not caring' or any of that is a logical fallacy. You have no idea how much effort they employed. You have no idea whether they care or not.
Admittedly, you're rather directly saying that you will judge anyone who uses this particular tool as 'uncaring' ('and I view that as not caring about those choices'). That's the same argument old-school graphic designers put forth against Photoshop, back in the day. Anyone who used Photoshop produced effortless, worthless slop and didn't care about their work, in their view.
I disagree, fundamentally. I also think it's a really weird hill to choose to die on. If the work is junk, it's junk, and it's still junk if they care passionately and use a ton of effort. If it's beautiful and meaningful, it's beautiful and meaningful. While it's vaguely possible that it's beautiful and meaningful because the monkeys typed Shakespeare, it's much more likely so because the author's choices throughout the creative process influenced the work to be so.
Now, if you want to argue that the bulk of LLM-generated work posted to SoL seems to evidence a lack of creativity and lousy prompting, be my guest. I don't disagree. But that's a statistical argument. It doesn't generalize to every work.
