Mind uploading
.svg?width=300)
Whole brain emulation (WBE) or mind uploading (sometimes called ""mind copying"" or ""mind transfer"") is the hypothetical process of copying mental content (including long-term memory and ""self"") from a particular brain substrate and copying it to a computational device, such as a digital, analog, quantum-based or software-based artificial neural network. The computational device could then run a simulation model of the brain information processing, such that it responds in essentially the same way as the original brain (i.e., indistinguishable from the brain for all relevant purposes) and experiences having a conscious mind.Mind uploading may potentially be accomplished by either of two methods: Copy-and-Transfer or Gradual Replacement of neurons. In the case of the former method, mind uploading would be achieved by scanning and mapping the salient features of a biological brain, and then by copying, transferring, and storing that information state into a computer system or another computational device. The simulated mind could be within a virtual reality or simulated world, supported by an anatomic 3D body simulation model. Alternatively, the simulated mind could reside in a computer that's inside (or connected to) a humanoid robot or a biological body.Among some futurists and within the transhumanist movement, mind uploading is treated as an important proposed life extension technology. Some believe mind uploading is our current best option for preserving who we are as opposed to cryonics. Another aim of mind uploading is to provide a permanent backup to our ""mind-file"", and a means for functional copies of human minds to survive a global disaster or interstellar space travels. Whole brain emulation is discussed by some futurists as a ""logical endpoint"" of the topical computational neuroscience and neuroinformatics fields, both about brain simulation for medical research purposes. It is discussed in artificial intelligence research publications as an approach to strong AI. Computer-based intelligence such as an upload could think much faster than a biological human even if it were no more intelligent. A large-scale society of uploads might, according to futurists, give rise to a technological singularity, meaning a sudden time constant decrease in the exponential development of technology. Mind uploading is a central conceptual feature of numerous science fiction novels and films.Substantial mainstream research in related areas is being conducted in animal brain mapping and simulation, development of faster super computers, virtual reality, brain-computer interfaces, connectomics and information extraction from dynamically functioning brains. According to supporters, many of the tools and ideas needed to achieve mind uploading already exist or are currently under active development; however, they will admit that others are, as yet, very speculative, but still in the realm of engineering possibility. Neuroscientist Randal Koene has formed a nonprofit organization called Carbon Copies to promote mind uploading research.
