In the same vein, airplanes can't fly because they don't flap their wings.
As for ignorance: have you tried to make an LLM produce the same output for the same input (as you state above)? Give it a shot, you'll be surprised.
And, to your point: I have, and I did, and I was not. If you’d like to refine your argument further - What LLM? Provide input how, and in what fashion? Under what conditions? - we can have that conversation, but if your assertion is “I can’t get ChatGPT to consistently produce the same output twice and therefore it is conscious,” that’s an incredibly facile argument.
You two seem to be laboring under the impression that this is terra ignota philosophically; it’s not. There’s an enormous amount of literature, thinking, ideas, concepts, frameworks, and approaches that already exist here that you’re welcome to engage with, but you’re not doing that, nor are you actually engaging with any of my arguments except to deny their existence.
Think that's what an out of touch techie would say? May I remind you that just a few hundred years ago the best philosophers were debating whether the world would descend into anarchy if more people realized that the big monkey in the sky doesn't exist. Just because philosophers talk about something doesn't mean it exists in reality.
As for same output - there's a parameter called "temperature". It governs the random wandering in the output of an LLM. Reducing temp gives more deterministic output, but also reduces the capabilities. Is it possible that randomness is also precisely the mechanism behind human creativity?
