Well - it's not hard to find. But ok:

Birch, The Edge of Sentience (2024), ch. 16 - "simply no way to assess sentience in an LLM"

Schwitzgebel, AI and Consciousness, (2025) — "we won't know before we've already manufactured thousands or millions of disputably conscious AI".

Butlin, Long et al., Consciousness in Artificial Intelligence: Insights from the Science of Consciousness, (2023) — "no obvious technical barriers to building AI systems which satisfy these indicators".

Let me know if you need more.
