The Edge of Sentience

Jonathan Birch explores the unstable boundary between sentient and non-sentient life, examining how science, policy, and ethics respond when inner experience cannot be conclusively measured. His focus is not on definitive answers, but on how societies should behave when knowledge is incomplete.

For American Cyborg, August sharpened the stakes introduced in July. Birch’s work connected animal consciousness, emerging AI systems, and human responsibility through a shared problem: uncertainty. Sentience, he argues, should be treated as a risk factor—one that demands humility and restraint rather than exploitation.

This month deepened the project’s ethical vocabulary. Intelligence was no longer framed solely as cognition or capability, but as something potentially accompanied by experience. August asked readers to imagine care not as sentiment, but as policy.
