Question

The year is 2079 and virtual reality has evolved into real reality, now electronic devices are used to control bodies from a distance, not game bodies made of pixels but real bodies made of flesh and sometimes silicon, plastic and metal. People can switch from one body the another with the same ease a game account can switch from one character to another for multiple playing experiences. The original client body which controls the other bodies can be put asleep while the other bodies are active or can be forced into automatic labor, just like some people with brain damage or almost completely destroyed brains can perfectly play music on various instruments or dance or wake up the morning and read the journal or books because those are things ingrained in the automatic parts of our bodies and after doing them for decades, brain activity or attention is not needed. client bodies can also be put into permanent sleep, starved and loaded with stress hormones and gene repairing viruses to slow down the aging process extending human life length by 3.7 times.

The majority of hive controlled bodies are clones, chosen from an array of designs, further customization is harder and requires more money. Other options are also manufactured bodies not made of flesh. But the government has decided to not imprison people anymore, to punish them, their frontal lobe is removed and replaced with a neural device so that they can be sold and controlled by other people.

Cellular phones came out in 1973 and today 06/06/2021 66.5% of the world population owns a mobile device, even my 6 years old brother has a smartphone, I got my first phone at the age of 21, technological evolution seems quite fast.

So how long before 100% of the world population will own alternative bodies they can control from afar, how long before new born babies will suck the milk from their's mother breasts who is an empty clone controlled by another person?

• Imagine it like in a video game, when creating a character you can either choose a preset design (clones) or customize it yourself... plus the option to play unique criminals and robots.

• Yes, stfu take my money and give me two. However why hive mind is just about body, I like to join borg collective eh? Dissatisfied 1star review, does not work for my dog as well ... Jun 6 at 15:30
• Never. There are certain advantages and trill, but if babies arent 40yo adults swapped body to suck some nastalgia, then it not so much useful. Not all people are gamers - it will, take about same widespread/share as gaming+porn(+-) - some are hardcore, some are casuals, but IRL goes on. There are some good advantages, no doubts, but fundamentally it should be better to take on things in the way u describe(at the end of the q), it has to give more, something fundamental Jun 6 at 15:36
• This is something regarding having a problem with the wording, but a hive mind would be one where the biological borders which make up some consciousness aren't separated present any longer, just like the left and right halves of the brain are connected, except it's several independent brains, Jun 7 at 0:02

It can't work.

Sleep isn't just a physical thing. Sleep is for processing the days events too. Things are filed in long term memory and things forgotten. It allows the mind to relax and unwind. Without actual sleep, people would go insane.

Personally you've gone the wrong way. You don't want a hive mind. What you want is a secondary brain.

Frame Challenge Brain 2.0

Just imagine spending a stressful day at work. You come home and you're bone tired and burnt out.

What will I cook for dinner? I better do some washing and cleaning. Better do some sit ups too because I'm putting on weight.

Well with new "Brain 2.0" worry no more. Just go to sleep on the lounge and your secondary brain will take over. Brain 2.0 will eat a salad, exercise, clean the house and fold the washing. When it's done doing all the jobs you didn't get to do, it will take a shower and hop into bed ready for you to wake up refreshed the next day after a full night's sleep.

• the brain is not just one unit but split into many sections, each doing some different work. That's why we can make conscious decisions in our sleep while we dream, that's why sleepwalkers exist, that's why people can live with only half of their brain, that's why people can talk, speak and think after a gunshot to the head while they die. It is perfectly possible to have part of your brain sleep and the rest of your brain alive, we've been doing it since the beginning... and if you don't believe me, look at dolphins and frogs, look at people with multiple consciousnesses in one single brain.

• Also there have been recorded people who only need 1 hour or even less of sleep time and they do not show any sign of memory loss or sleep deprivation, even after decades of doing it.

• @Belle after that 'just that no animal ever has found a reason to evolve it.' Not sure u know what you are talking about. There are some good, resonable points in u comment, but - "Dolphins only close one eye when they sleep; the left eye will be closed when the right half of the brain sleeps, and vice versa. This type of sleep is known as unihemispheric sleep as only one brain hemisphere sleeps at a time." Jun 7 at 18:19
• @Bell Sharks sleep while swimming so sleep isn't about conserving energy. Jun 7 at 23:09
• @Thorne brains consume more energy than muscles. walking consumes between 1.7 and 4 kilocalories per minute for most humans, running burns twice that. Whilist a Chess Grandmaster who plays a game sitting on their ass all day burns up to 6000 kilocalories in a day... just sitting and thinking... compare that to the 2800-3500 kilocalories a heavy labor worker burns... The brain burns way to many calories just thinking, there's no reason for the brain to be awake at night when it's too dark and dangerous to do anything, wasted energy.

Knowing human nature, forever.
There will always be a small percentage of body purists, religious fanatics, the ultra-squeamish, and the plain old stubborn-refusing-to-change who will resist the adoption of such a radical new lifestyle.

Example: There are currently some 5000-10000 US citizens that chose to live in the wilderness with no car, no electricity, no books.
There's an additional about 300000 Amish that are similar but less extremely so. They might allow battery-powered lights, for example. But cellphones? God Forbid! (literally)

## Hive Minds Aren't Free

The raw map of all synaptic connections in a human mind takes up about $$1 \times 10^{18}$$ bytes (1 hexabyte) of memory.

To send this whole data package across a fiber optic cable using red light (405 THz) takes about an hour (61 minutes), using a single channel. You can use more channels. Of course, if you are wireless, you won't want to go any higher frequency than near-infrared.

With AM modulation, you can space channels about 10 kHz apart (or about 10 billion channels) before you are out of the infrared band altogether.

With FM modulation, you can space channels about 25 kHz apart (or about another 4 billion channels).

So, wirelessly :

• 7 billion human beings using this network can at most be using 2 channels at a time (30 minutes to transfer a raw mind point-to-point).

With fiber optic trunks, the situation doesn't improve much (750 THz). You may ask, "why not go x-ray? Or cosmic rays?" Physical materials tend to be damaged by anything much more high-energy.

So a composite network of wifi and fiber optics give you about 38 billion channels. Or 4 channels per person (about 15 minutes to move a mind around).

A quantum cable may allow you to modulate by phase, flux, and spin. But you get the idea - there is a limit, and for a planet of a few billion users, it's not as big a limit as we would all probably want.

If you want a "live" hive mind feed, everybody needs to be able to move in under the frame rate of the mind (4 Hz ~ 0.25 seconds). That takes about 10 thousand channels per (+1 in the hive mind)

• 2 people : 10k channels (0.0001% of global bandwidth)
• 3 people : 30k channels

Clearly, only about 10 million people can be physically using this system at the same time.

The other 6.99 billion of us are going to have to opt out.

There are ways you can extend utilization:

• Not live : the clone(s) operate autonomously and sync back with "you" at some interval (maybe during a sleep cycle). This operation takes an hour, and lets all 7 billion of us have up to 20 clones; or participate in a hive-mind of up to 20 friends.

But your missing out on the opportunity cost.

If you can move minds, you can transfer skills. There's already a lot of work being done on that. Want to learn Kung Fu? Ancient Greek? All languages? Universities could probably lend skills, or outright sell them for download (probably lend, knowing how people are). That all takes up bandwidth. I think most people would be willing to trade 20 clones for 100 new skills.

In fact, employers will probably expect employees to be as skilled as they can afford. Marginal utility strikes again.

Depending on the Gini Index of your world (how many people have "mean" income), maybe half of your people will face economic pressure keeping them from ever "going clone", unless it's required for work.

This jives with reality. Although the U.S. only has a few thousand people living extremely rural lives (it's an extremely rich nation), most of the 7 billion people of Earth (about half) live in rural conditions.

And the law of supply and demand.

If the top ten million richest people on Earth can afford live clone hives, and are willing to pay for it, then the bottom 99.9% are locked out.

To the extent that some at the top won't use all of the multiplicity they can afford, I'd think at most 30% will be able to adopt.

• Interesting angle on the problem, there is some validity to the answer. However, mm isn't it enough to project information for visjal cortex and plus some for senses, then we do not talk about petalion synapses which do not fires all the time at once(maybe) Jun 11 at 5:58
• My feeling is that video and sensory only is going to feel like trying to wear two VR headsets at the same time. Management software could exist that allowed the experience to be managed like having two televisions in the room, or clone control could be made very abstract with an interface allowing the user very general commands “go here”, “do that” and pre-installed software figures out the details. But neither of these options sounded like the live, fully immersive experience being asked for in the question. Jun 11 at 11:19
• When you smell cookies and it reminds you of Mom, that’s deeper than just the sense. Especially if, at the same time, you want to feel the ocean breeze blowing through your hair. I feel like this fidelity of experience probably requires fully-capable nodes to do the experiencing, and the sum of changes is synchronized across the group. I could be wrong about that. Jun 11 at 11:23
• Sure fidelity have to be high enough but even then it is not about simulating full neroactivity of ones self, ones body will do it on its own if right input stimulus will be provided to correct neurons. I do not see neccessity of syncing two brains in realtime at least, but sure it may depend on OP. Spinal cord is a bus for ones mobility and taktile perception, similar buses exists for visual and for hearing. You middleman your devices in those and it sure will be better than just VR, or more live like. And you translate environment impulses into corresponding neurons activity locally Jun 11 at 12:38
• @user85880 copying not for communication, it just another option with its properties. I mention it for James to have opposite example, so he could push himself away from that synapses sync thing. As for dreams, I guess people are wired differently in that regard, so I definetly see value for it to not be dream like expirience(never had dreams like yours to be vivid etc). Comments limiting things, but yes I do mean that information exchange isn't so big. Jun 12 at 0:44

About years idk, but here's my best guess with growth starting in 2040

For hypotheticals let's say that a neural link which works to that degree is widely distributed to the market in 2040. So, if were to then go on the basis of smartphone growth, assuming the same level of accessibility with regards to the technology(which is, a given a bit an of a shaky assumption, but let's just run with it). Drawing from stasticia, global smartphone phone penetration had reached about a bit over 79% in 2020, as this represents when the technology was perfected, and given current growth trends without regards to other variables, such as groups for which this isn't reachable, it should reach 99% penetration by 2030(realistically this would be lower due to some groups and some areas of the world not having the infrastructure to allow for smartphones) The, given the optimistic scenario, such a thing would be present worldwide at about 2052-2056. More realistically, due to the demographics and infrastructure required it would probably be around, in the vein of realistic optimism, 20%, as this would require advances in CLONING, ROBOTICS, and NEUROLOGICAL COMPUTER INTEGRATION, much lower, meaning that I'd guess around, bu 2078, then in this vein of optimism, around 30%. But then again I don't know a thing about what I'm talking about so take everything I said with several garbage trucks of salt.
