#152 Why AI Will Never Be Conscious

Apr 20, 2026 · 1h 41m

Summary

Anil Seth argues that AI consciousness is a myth, distinguishing intelligence (doing) from consciousness (feeling). He contends that biological substrates and metabolic processes are essential for experience, challenging the view that silicon-based computation can replicate it. Seth also explains how human psychological biases and the seductive nature of language models lead us to falsely attribute awareness to machines.
