THE TURING THRESHOLD

Artificial intelligence did not arrive by accident.

It is the consequence of a long evolutionary process-one that began with chemistry learning to remember, accelerated through human tools and institutions, and now approaches a critical threshold where intelligence itself becomes a selectable, non-biological substrate.

In The Turing Threshold, Chandrashekar Babu reframes AI not as a conscious machine or an existential threat, but as a structural inevitability: the outcome of systems that reward speed, scale, and recursive optimization over biological limits. Drawing on physics, evolutionary biology, history, economics, and computer science, the book traces how intelligence has steadily externalized itself-from muscle to memory, from symbols to silicon-and why that process now approaches a point of no return.

This is not a story of human obsolescence, but of structural continuity.

It gestures toward an interstellar future-where cognition persists beyond biology, geography, and epoch-carried forward by the very systems we are now setting in motion.

This is not a book about what the future should be.

It is about what futures remain possible once the threshold is crossed.
