Unsure if this is a useful answer. But Searle/LLM could make something that looks like it has a creative spark, and that's it.
Why I think that's different is in the case of a human artist, they create something because they have something they want to say. Whatever they produce is a way of saying 'this is what the world feels like to me, is it the same for you?'. And if it is, it resonates.
But I cannot see how an LLM would 'want' to say anything. If we're talking psychoanlytically of where wanting comes from, and call it a desire to fill a void of how incoherent you actually are, then an LLM doesn't go through that process.
Maybe Searle does, and still wants the characters to make you feel a certain way, in which case the comparison doesn't fit.
Yes, DP breeds expertise. But I don't think you can just decide to do DP.
An expert craftsman/woman does that craft everyday because they LIKE doing it, expertise might not even be the goal. Think of Nobel Prize winners, is the core thing that they did DP, or is it they were having enough fun (loose definition) that DP is how they wanted to spend their time.
I think the lesson for a young person is still find what you love. But with this you can say: find what you love, then sacrifice yourself to it.
I think there's something in how a good shrooms high makes you feel that 'you' are less real, and that something like nature is more cohesive and real than you are used to thinking about it.
But as someone else said, the next day you don't care anymore and you don't actually think you unlocked a new dimension. The experience of what drugs feel like doesn't seem like a valid way to get at the true nature of anything.
Was ready to be super sceptical but this is interesting. The measure gets at ways of showing uniqueness (e.g. defending a view thats different from everyone else's, not caring what others think). So I can buy that has descreased.
What I bet hasn't decreased is the extent to which people say they want to be unique.
And on your ceramics point. That sounds like hell to me too. But maybe that's why neither of us make pots.
