Whole brain emulation: A roadmap

Abstract

Whole brain emulation (WBE), the hypothetical future simulation of the human brain, holds significant academic and societal implications. From a research perspective, WBE represents the ultimate goal of computational neuroscience, enabling a deeper understanding of the brain through comprehensive modeling and providing an ideal testing ground for neuroscientific exploration. This endeavor could also yield practical applications in fields like pattern recognition, AI, and brain-computer interfaces. Economically, the impact of copyable brains could be substantial, potentially leading to profound societal changes. On an individual level, WBE could offer the possibility of backup copies and “digital immortality” if ethical and identity concerns are addressed. Philosophically, WBE challenges existing ideas about the mind and identity, potentially representing a radical form of human enhancement. While formidable, WBE appears achievable through the extrapolation of current technologies, unlike many other transformative technologies like artificial intelligence. To explore the feasibility of WBE, the Future of Humanity Institute hosted a workshop in 2007, bringing together experts from various fields to discuss the possibilities, challenges, and necessary milestones for realizing this ambitious goal.
