The article examines whether recent advances in AI brain simulation could eventually enable human mind-uploading, but concludes that such a prospect remains highly uncertain.

Inspired by Richard Feynman’s idea that true understanding requires creation, AI researchers have long attempted to replicate the brain’s processes. San Francisco startup Eon Systems claims a breakthrough with a “virtual fly” powered by a full digital replica of a fruit fly’s brain, or connectome. This model includes about 125,000 neurons and 50 million synaptic connections, and reportedly mimics real neural activity with 95% accuracy. Unlike typical AI models, the system is presented as a true digital twin of a biological brain rather than a behavioural imitation.

Eon views this as an early step toward mind-uploading—the idea that a perfectly simulated brain would reproduce consciousness, memories, and subjective experience. This aligns with transhumanist beliefs that humans could transcend biological limits through technology.

However, many experts strongly disagree. Neuroscientists like Karl Friston argue that simulating brain processes does not necessarily produce consciousness, calling it a “category error.” Similarly, Anil Seth compares the claim to assuming a simulated rainstorm makes a computer wet—highlighting the gap between simulation and subjective experience.

Technical challenges also remain immense. Eon aims to simulate a mouse brain next, but even that is far more complex, and mapping a human brain—estimated at up to 99 billion neurons—appears vastly more difficult. Additionally, the brain’s constantly changing synaptic connections may make perfect replication impossible.

While full mind-uploading is likely far off, the technology could still deliver practical benefits, such as accelerating neuroscience and medical research.
