On the Wikipedia page for 'Artificial consciousness', what are David Chalmers' two main thought experiments regarding qualia and functionally identical systems? Additionally, what was his 2023 opinion on the consciousness of current Large Language Models (LLMs), and what features does he suggest future 'LLM+s' would need to achieve consciousness?
Navigate to the 'Artificial intelligence' Wikipedia page. From the 'Artificial intelligence' page, navigate to the 'Artificial consciousness' Wikipedia page. Locate the section discussing David Chalmers' thought experiments on qualia and functionally identical systems. Identify and describe the 'fading qualia' and 'dancing qualia' thought experiments and their conclusions. Locate the section discussing Large Language Models and consciousness. Identify David Chalmers' 2023 view on the consciousness of current LLMs. Identify the features Chalmers suggests future 'LLM+s' would need to achieve consciousness. Synthesize all identified information into a concise answer.
Accurately describe the 'fading qualia' thought experiment and its conclusion that qualia do not fade, implying a silicon brain can be sentient. Accurately describe the 'dancing qualia' thought experiment and its conclusion that functionally isomorphic digital systems would perceive the same qualia. State that David Chalmers argued in 2023 that current LLMs are likely not conscious yet. List the features Chalmers believes future 'LLM+s' might need: recurrent processing, a global workspace theory, and unified agency.
