Episode notes
Need for a Theory of Consciousness
- Scientists need a theory of consciousness to address complex questions.
- This theory should explain which systems have feelings and when a fetus or machine becomes conscious.
Consciousness as Subjective Experience
- Christoph Koch views consciousness and awareness as interchangeable terms.
- He emphasizes the subjective, phenomenal nature of consciousness, encompassing feelings and sensations.
Computational Functionalism vs. Consciousness
- Many in AI believe consciousness is a computation, achievable by mimicking human actions.
- Koch argues this is 'computational functionalism' and believes Large Language Models (LLMs) are faking consciousness.
