This book investigates whether humans and artificial intelligence systems can share concepts and engage in meaningful communication. Herman Cappelen and Josh Dever, both established philosophers, utilize the externalist tradition in the philosophy of language to construct theoretical models for human-AI interaction. By applying these metaphysical frameworks, the authors argue that current philosophical approaches to meaning can be refined to better account for the emergence of non-human intelligence.

Experts in the philosophy of language recognize this work as a bridge between classical analytic philosophy and contemporary technological challenges. Readers frequently note the academic density of the prose, which requires a foundational understanding of semantic externalism to fully grasp the authors' arguments.
