Yes, that was obviously an extreme example. But we know that it is possible in reality to implement a physical system that does what we call thinking. There is, I think, no particular reason to suppose that it's physically impossible re-implement the functionality with much less meat. Supposing that you've done this, you then just need to more clearly define "thinking" and "LLM" to determine whether changing that re-implementation to be closer to an LLM results in it losing the ability to think before it gets there.
