Mind uploading
hypothetical copying of a "self" from a brain's neural-networks into a computer, a computer network or a human-like robot
Mind uploading is a hypothetical process of whole brain emulation in which a brain scan is used to completely emulate a person's mental state in a digital computer. The computer would then run a simulation of the brain's information processing, such that it would respond in essentially the same way as the original brain and have a sentient conscious mind.
Substantial mainstream research in related areas is being conducted in neuroscience and computer science, including animal brain mapping and simulation, development of faster supercomputers, virtual reality, brain–computer interfaces, connectomics, and information extraction from dynamically functioning brains. Supporters say many of the tools and ideas needed to achieve mind uploading already exist or are under active development, but they admit that others are, as yet, very speculative, though still in the realm of engineering possibility.
Mind uploading may be accomplished by either of two methods: copy-and-upload or copy-and-delete by gradual replacement of neurons (which can be considered gradual destructive uploading) until the original organic brain no longer exists and a computer program emulating it takes control of the body. In the former method, mind uploading would be achieved by scanning and mapping the salient features of a biological brain and then storing and copying that information into a computer system or another computational device. The biological brain may not survive the copying process or may be deliberately destroyed during it. The simulated mind could be in a virtual reality or simulated world, supported by an anatomic 3D body simulation model. Alternatively, the simulated mind could reside in a computer inside—or either connected to or remotely controlled by—a (not necessarily humanoid) robot, biological, or cybernetic body.
Among some futurists and within part of the transhumanist movement, mind uploading is treated as an important proposed life extension or immortality technology (known as "digital immortality").
Begin with the source’s own compact description: “Mind uploading” is hypothetical copying of a "self" from a brain's neural-networks into a computer, a computer network or a human-like robot. The dossier treats that line as a proposition to test through Mind, uploading and hypothetical, not as a finished interpretation.
Why this record matters
The phrase “hypothetical copying of a "self" from a brain's neural-networks into a computer, a computer network or a human-like robot” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q2267982. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
