Have you ever felt like life was strangely familiar? Like you had lived this moment before? Or had a weird sense of deja vu when talking to a new friend?
Moments like these have made iconic innovators like Elon Musk wonder if our reality is some kind of ultra-realistic simulation.
This thought experiment is known as Simulation Theory – the idea that humans are actually living in an advanced virtual simulation created by our highly evolved future selves. In this matrix-like simulation, everything would look and feel indistinguishable from "real" physical existence.
Intriguing? Definitely! But could it be possible? Is our world just an incredibly high-def video game? Let‘s dive deeper to understand what the simulation theory is all about!
What Exactly is the Simulation Theory?
The term "Simulation Theory" originated from a 2003 academic paper titled "Are You Living in a Computer Simulation?" by philosopher Nick Bostrom.
In his influential paper, Bostrom made the case that at least one of the three following statements is very likely to be true:
- The human species is very likely to go extinct before reaching a "posthuman" stage with advanced superintelligence capabilities
- Any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history or variations thereof
- We are almost certainly living in a computer simulation created by posthuman civilizations
This trilemma implies that if advanced human civilizations do survive to create ancestor simulations, then the probability becomes overwhelmingly high that we are among the simulated minds rather than among the original biological ones of that posthuman stage.
In plain speak – if humans invent the matrix, chances are high we are already in it!
While a fringe idea for decades, the simulation concept entered mainstream discourse whenvisionary thought leaders like SpaceX Founder Elon Musk repeatedly endorsed its validity.
"There‘s a billion to one chance we‘re living in base reality," Musk famously proclaimed existentially on stage in 2016. And Musk is far from alone in pondering our simulated probability!
How Would Such a Simulation Work?
For a species to create a simulated existence like our perceived reality, the computational capacity required would be absolutely mammoth!
Every environmental detail would need algorithms. Every person and creature would need backstories encoded. Not to mention programming consistent laws of physics, organic reactions, emotions, history, culture – basically everything that defines life and society today mapped inside a virtual dimension.
To put things in perspective, one of the world‘s fastest supercomputers today is Frontier at the Oak Ridge National Laboratory, capable of performing 1.5 exaFLOPS (That‘s over a quintillion floating point operations per second!)
Yet running a real-time simulation for just one human lifetime at a normal frame rate may require an astronomical 30,000+ exaFLOPS of processing power by even the most conservative estimates!
So will computers ever be capable of such blistering benchmarks?
| Year | Top Supercomputer Benchmark | Hardware Used |
|---|---|---|
| 2022 | 1.5 exaFLOPS | AMD Epyc + Radeon Instinct |
| 2016 | 125 petaFLOPS | TaihuLight Sunway SW26010 |
| 2011 | 17.59 petaFLOPS | K computer SPARC64 VIIIfx |
| 1997 | 1 teraFLOPS | ASCI Red Intel Pentium Pro |
Interestingly, supercomputer speeds show reliable exponential growth curves, doubling every 12-18 months. Known as Moore‘s law, this long-term trend is expected to continue for at least another decade via novel materials like graphene.
Extrapolating forward, conservative models predict we could achieve simulated-human-level compute between 2050 and 2100 – very conceivably within the lifetimes of Gen Z and millennials!
So in the big picture, Musk‘s simulation-skepticism doesn‘t seem so far fetched after all!
If advanced simulations are eventually possible, they may serve a variety of entertainment, scientific or social purposes – both utopian and dangerous.
Why Would Future Humans Create Such Simulations?
"But why would anyone go through this much effort just to simulate reality inside reality?" you may ask.
Fair skepticism! Building this virtual layer would require astronomical resources and next-gen engineering. So there would likely need to be a big incentive for posthuman civilizations to make the investment.
Common motivations cited by simulation supporters include:
- Entertainment: Imagine our world as the ultimate VR roleplaying game or CGI movie! Future folks could plug in and live out any customized life imaginable.
- Science: Simulations allow revolutionary analysis across biology, sociology and alternative physics compared to experiments confined by ethical concerns. Think cloning dinosaurs without consequences!
- Preservation: Civilizations may simulate past eras to preserve history, culture and lost knowledge through cataclysms. Like a virtual museum meets time machine!
- Education: High-fidelity ancestral simulations could allow the posthumans to visit and directly learn from historic thought leaders like Da Vinci, Einstein, etc.
- Transcendence: Moving human minds into virtual worlds may enable quasi-immortality and utopian afterlives according to thinkers like Ray Kurzweil.
Of course, the motivations and applications could be far more radical than anything we can conceive today. After all, the post humans simulating us would be DIVINE compared to our primitive chimp-brained selves!
Philosophical Perspectives on Simulation Theory
The simulation concept touches on profound existential questions about the meaning of reality and humanity‘s role within it.
For instance, if simulated universes have conscious residents, would deleting or altering their worlds be murder or exploitation? Do these digital beings deserve rights? Can bits and logic gates have souls?🚀
Or does only base reality matter ethically? In math terms – Is a nested simulation still sacred math even if the base layer vanishes?🌀
Other mind-bending paradoxes arise too…
Are YOU the real conscious self reading this now? Or just an ephemeral simulated imprint of your ancestor‘s personality, believing itself real? 👀
And recursively – what if THEIR reality was also simulated by more advanced simulators? Simulations all the way up and all the way down? 🤯
At some point all this overlapping relativity starts feeling an awful lot like religion or spirituality masked in futurist garb!
Ultimately, it‘s unlikely we can ever conclusively prove or disprove something as meta as simulation theory from INSIDE this perceived existence. Like a video game character in Grand Theft Auto attempting to discern hidden Xbox firmware!
But wrestling with such fun logic puzzles sure makes our brief stay in this particular universe a bit more colorful! 🎨
So whether top layer, sublayer or base reality, remember to enjoy the ride friends! 🎢
