Sure! But if I experience it, and then write about my experience, parts of it become available for LLMs to learn from. Beyond that, even the tacit aspects of that experience, the things that can't be put down in writing, will still leave an imprint on anything I do and write from that point on. Those patterns may be more or less subtle, but they are there, and could be picked up at scale.

I believe LLM training is happening at a scale great enough for models to start picking up on those patterns. Whether or not this can ever be equivalent to living through the experience personally, or at least asymptomatically approach it, I don't know. At the limit, this is basically asking about the nature of qualia. What I do believe is that continued development of LLMs and similar general-purpose AI systems will shed a lot of light on this topic, and eventually help answer many of the long-standing questions about the nature of conscious experience.
