Again: “AIs aren’t conscious” is a strong, affirmative claim. It implies a lot of specific things about consciousness. It requires strong evidence. “We can’t say for sure if AI is conscious” is a weaker, cautious claim. It doesn’t make any particular evidence about consciousness.
No idea where he gets the idea there is any evidence for token prediction models being conscious, but "that's absurd" is only a strong claim if the rejected idea is not absurd. In this case, it is. Repeating myself here, but start an LLM session and watch what it does if you don't provide a query.
