That is the same categorical argument as what the story is about: scanned brains are not perceived as people so can be “tasked” without affording moral consideration. You are saying because we have LLMs, categorically not people, we would never enter the moral quandaries of using uploaded humans in that way since we can just use LLMs instead.

But… why are LLMs not worthy of any moral consideration? That question is a bit of a rabbit hole with a lot of motivated reasoning on either side of the argument, but the outcome is definitely not settled.

For me this story became even more relevant since the LLM revolution, because we could be making the exact mistake humanity made in the story.
