In der Science Fiction ist es seit Jahrzehnten ein bewährtes Thema: die Speicherung bzw. Nachbildung eines menschlichen Bewußtseins als komplexes Programm, als Form einer technisch ermöglichten Unsterblichkeit. (Unterabteilungen sind die Simulations-Hypothese à la Nick Bostrom, die die Möglichkeit postuliert, daß dies längst der Fall ist und wir selbst Teil eines solchen Silumation sind; Frank Tipler hat dies 1994 in seinem Buch The Physics of Immortality als Endziel der biologischen/technologischen Evolution auf hunderten Seiten nicht-wirklich-überzeugender Mathematik ausgebreitet). The Encyclopedia of Science Fiction, Stichwort "Upload":
Zitat This real-world term for the transfer of data to a remote Computer (for example, new or amended web pages to a website host) has taken on a special sf significance as denoting the copying or transfer of a human or other personality to a sentient software representation. Interesting early examples are "Ghost" (May 1943 Astounding) by Henry Kuttner and C L Moore, in which the final despair (if not the full personality) of a suicidal depressive becomes impressed on a supercomputer which rebroadcasts the emotion; "Think Blue, Count Two" (February 1963 Galaxy) by Cordwainer Smith, in which a semi-organic computer based on a "laminated" Mouse brain is imprinted with multiple human personalities; "Point of No Return" (July 1963 New Worlds) by Philip E High, where soldiers operating Weapon systems by remote telefactoring suffer inadvertent personality transfer to their machines; The Ring of Ritornel (1968) by Charles L Harness, in which portions of an unwilling human's brain are physically transferred into a Music-making computer – the result being strictly speaking a Cyborg; "The Schematic Man" (January 1969 Playboy) by Frederik Pohl, whose protagonist encodes himself as a computer program; Midsummer Century (April 1972 F&SF; rev 1972) by James Blish; Catchworld (1975) by Chris Boyce; "Fireship" (December 1978 Analog) by Joan D Vinge; and Engine Summer (1979) by John Crowley, whose hero's aspirations to sainthood are fulfilled by upload into a recording device as an exemplary life which others may experience in full.
More recently the notion of uploading human personalities into machinery has been used very promiscuously indeed, being one of the key corollaries of the notion of Cyberspace. It is featured in Vernor Vinge's proto-Cyberpunk story True Names (1981 dos), and became a virtual Cliché in the years that followed. Updating the traditional sf Cyborg transformation, the protagonist of Rudy Rucker's Software (1982) is transferred as pure information to a Computer that transparently operates, but is too large to be built into, his new Robot body. Frederik Pohl's Heechee Rendezvous (1984), Greg Bear's Eon (1985), Greg Egan's Permutation City (1994), Robert J Sawyer's The Terminal Experiment (1995) and Tad Williams's Otherland quartet – beginning with Otherland: City of Golden Shadow (1996) – all propose that various kinds of software afterlife may one day be more or less universally on offer. The attractions of such Virtual Reality versions of Heaven are obvious, if slightly dubious: is copied brain-state information a true representation of personal Identity? Permutation City suggests some more practical drawbacks, including shortage of processing power and lack of real-world depth in virtual scenarios, and further difficulties emerge in David Langford's "New Hope for the Dead" (26 May 2005 Nature).
Zitat NEXTA@nexta_tv This is no longer science fiction: scientists are experimenting with transferring consciousness In early March, a San Francisco startup digitized a fly’s brain and launched it in a virtual body. They copied the entire nervous system — about 125,000 neurons and tens of millions of connections. And it works. This is not AI in the usual sense: the brain inside the computer independently controls the virtual body. It moves, reacts, and “lives” without predefined commands or algorithms. Behavior emerges on its own, like in a real organism. Importantly, the fly was not trained. This is a copy of a living brain that continues to function in a different environment. The project is called EON Systems. The next step is a mouse brain, and then a human one. For now, it sounds like theory, but scientists are steadily moving toward digital immortality. 3:30 AM · Mar 18, 2026
Zitat Announcement — March 8, 2026 - We've Uploaded a Fruit Fly
We've uploaded a fruit fly. We took the @FlyWireNews connectome of the fruit fly brain, applied a simple neuron model (@Philip_Shiu Nature 2024) and used it to control a MuJoCo physics-simulated body, closing the loop from neural activation to action.
It's crazy that this worked. The uploaded fly has 91% behavior accuracy with only 4 things:
the graph of connections the weights as determined by the number of synapses connecting those neurons a map of excitatory and inhibitory neurons leaky-integrate-and-fire
This shows how much information is captured by the architecture itself, rather than the neuron model, which is great for the feasibility of full emulation.
Some caveats: We can't trace the actual motor neurons because the body was not scanned. However we do know what the brain does when it wants to move in certain ways and that's what we connected to the NeuroMechFly. This is a real limitation of the FlyWire connectome, which is why we plan to scan both the brain and the body.
Another limitation is that we're using Leaky Integrate-and-Fire, which doesn't have any kind of plasticity rules. This fly cannot form long-term memories atm.
We're entering an era of artificial superintelligence. The biggest question isn't whether ASI will arrive — it's what form it takes and who gets to participate in it.
Right now the default path is: a few labs build opaque AI systems, and the rest of humanity hopes they're aligned. I think there's a better option.
A successful hi-fi upload should feel like you. You that is robust, free from illness and death; editable, can run faster than real time and keep up with AI (transistors are a billion times faster than neurons); and most importantly aligned, with your values, memories, relationships, and moral intuitions.
