The First Brain Manifesto Calls for AI That Strengthens Human Thinking

Summary

Serhii Kravchenko’s “The First Brain” manifesto argues that the AI industry has focused on building a “Second Brain” that stores notes, meetings, and information, while neglecting the biological brain that produces ideas. Drawing on cited findings about walking and creative ideation, the Google effect, retrieval-based learning, and sleep-based memory reactivation, the manifesto claims that outsourcing recall and understanding can weaken the cognitive activities that build comprehension. It defines a First-Brain product as one that uses AI to strengthen the user’s mind rather than think in the user’s place. The proposed distinction is between replacement, where AI drafts, decides, or digests on a person’s behalf, and amplification, where AI works on the person’s own thoughts and helps carry them into finished results. The document connects this approach to earlier ideas from Ross Ashby, J.C.R. Licklider, and Douglas Engelbart about intelligence amplification and human-computer symbiosis. It presents large language models as the first technology capable of beginning this work, while noting that current non-invasive sensors and neuroscience research do not read minds. Practical directions include capturing ideas during walking or other generative states, turning spoken thoughts into finished work in the speaker’s voice, and eventually using targeted memory reactivation to reinforce a person’s own ideas. The author presents the manifesto as the starting point of a longer research program rather than a released product.
