Digital immortality is a theoretical concept of storing or transferring a person's consciousness
into a computer, a virtual body, or a robot.
Required Technologies Adequate hardware to simulate and map a human
mind will likely become available as early as this decade.
However, our available software will be nowhere close to making this possible.
The human brain is far too complex to adequately scan in the near future.
It contains about 86 billion neurons with more than 125 trillion synapses between those
neurons.
That would equate to 2.5 Petabytes of data or 2,500 terabytes, according to a rough estimate
published by Scientific American.
Before digital immortality can become a reality, multiple breakthroughs will need to occur.
These breakthroughs include the following: • We would need the ability to model each
region of the human brain with an adequate amount of detail.
• We would require software that is powerful enough to match electrical signals and brain
structures with specific memories and thoughts and transfer that information to digital file
systems.
• And we’ll need the capability to transfer simple memories and thought patterns with
brain-computer interfaces.
Eventually, those interfaces will need to transfer extremely complex thought patterns
and memories.
And once those breakthroughs are achieved and uploading minds actually becomes possible,
there may be multiple legislative obstacles in the way because of concerns that the procedure
is inhumane.
This video will delve more into that toward the end.
The Processes of Uploading a Mind More than likely, nanobots will become the
preferred technology for scanning and copying human minds.
That is because they can capture every prominent neural detail inside a person’s skull.
Nanobots are robots that are the size of human blood cells and they’re comprised of carbon
atoms.
Nanobots can be considerably smaller than that, but after a certain size threshold,
they’ll start to lose practical functionality.
Billions of nanobots could travel through every brain capillary, scanning each relevant
neural feature from up close.
Using high-speed wireless communication, the nanobots would communicate with each other
and with a nearby computer that is assembling digital models of a person’s brain regions.
Another process involves removing individual neurons from a person’s brain and creating
duplicates of those neurons in a synthetic brain that is in a connected robot nearby.
The person undergoing this procedure would remain conscious as more and more neurons
are replaced.
Eventually, after all the person’s neurons have been replaced, the connection between
the person and the robot is finally cut.
At that instant, the person wakes up in the robot body and gazes back at their old body
that is now lacking a brain.
Initially, mind uploading could be tested on mice and larger mammals.
Once this procedure is determined to be safe, it could be made available to the public with
a potentially sizable price tag.
Eventually, people in most developed countries could have access to special clinics where
they can upload their consciousness to computers.
Positive Impacts On Society After the upload takes place, a digital consciousness
could exist in two primary scenarios: In the first scenario, a person's consciousness
could be transferred to a cloud service where it could interact with the physical world
and interact with virtual worlds.
This could lead to all types of fascinating situations.
Someone’s consciousness could live in a virtual paradise for tens of thousands of
years or perhaps much longer.
The user could travel between virtual worlds as they see fit and gain access to downloadable
content to enhance their experience.
While someone is physically still alive, they could work with digital clones of themselves
to accomplish their most important life goals much faster.
Some digital humans could spend an eternity building business and government empires.
Others could upload themselves to computers on spacecraft and travel to other solar systems
while putting themselves on pause for hundreds or thousands of years at a time.
While others could merge with superintelligent AIs and create new technological innovations
that revolutionize the world.
In the second scenario and in the far future, individuals could have entirely new bodies
grown or built.
The least expensive models could be visibly robotic or machine-like in appearance.
Many decades from now, these bodies could also be completely indistinguishable from
real human bodies.
The most expensive synthetic bodies could have numerous hi-tech add-ons and internal
features to greatly boost physical and mental capabilities.
Over the next hundreds and thousands of years, these synthetic bodies could become so advanced,
that they could surpass the wildest imaginations of most people today.
And synthetic bodies could be swapped and replaced as they wear out and more updated
versions are made available.
When will it become possible?
Futurist Ray Kurzweil once predicted that in 2045, we'd be able to back up our minds
to the cloud.
Some people believe it will take anywhere from 100 to 200 years before it's largely
perfected.
And that's with the assumption that it will ever become physically possible.
Is Digital Immortality Potentially Dangerous?
However, the prospect of digital immortality raises some important questions.
Would the digital version of you really be you?
Or, as Ray Kurzweil put it, is it another person who just happens to have mastered your
thoughts and memories?
And the longer a digital copy of someone exists, the less its personality and motivations would
resemble the original person.
Also, after your consciousness is placed in a virtual world, what kind of rights would
your virtual counterpart have?
Could the company that owns the server that contains your digital consciousness have ownership
over that consciousness as well?
What if that server changes hands or that company is acquired by another company that
is far less ethical?
And if your consciousness is in a virtual world, and that virtual world changes over
time in a way that is detrimental to your digital self?
There's the potential that your consciousness wouldn't be able to do anything to change
that situation.
Digital immortality could cause society to stagnate.
As Elon Musk put it, if too many people live forever, we’ll be stuck with old ideas and
society wouldn’t advance.
Lastly, there are certain types of people who would cause tremendous and long-term harm
to the world if they were able to live forever.
And they could have the most resources leading them to have the most opportunities to access
this technology.
These people include self-appointed dictators that constantly put the entire world on edge
because of their outdated ideologies.
A wide range of criminal overlords could also one day gain access to this technology.
