>Download brain into new body

This is the tricky bit. What do you mean by download?

In any case it is silly to fear death. If anything, it is something to be grateful for.

Explain how consciousness can be transferred from one brain to another.

Why not just put your brain into the cranium?

>>9254713

I'm saying that's possible, but not understood right now.

>>9254715

Kill him and then yourself, in that case.

>>9254729

Unless you can clean of aged cells and plaques, otherwise you'd have old age diseases in your teens.

>>9254689
No, you either die with that or this >>9254715 happens

Instead, you must ship of thesus yourself slowly. Its the only way to be sure you stay you (that and never sleeping)

>>9254689
What horror it would be to die knowing that a copy of you would persist. Only the outside world believing that this copy is still you, while you, the real you have experienced death and are gone.

Because when data is 'moved' it is duplicated at the destination and deleted at the source, surely you understand that. That the data is your previous conciousness is not relevant to this cold and simple process.

>>9254745

No you have to move, not copy the data.

>>9254746
That is impossible. It is now and will always be impossible.
Perhaps you want to grow a human vegetable, scrape out his smooth brain and pop your brain in. You need to put the pilot in a new vehicle. You cannot have two pilots and say they're the same guy. Information cannot be destroyed.

>>9254753

So what's the work around, brain transplantation?
I suppose the tech to "de-age" the brain would be more plausible than data transfer.

What's wrong with dying knowing there's a "copy"? In what way is this copy not you?

>>9254757
>I suppose the tech to "de-age" the brain would be more plausible than data transfer.
Probably

>>9254753
This anon is correct.
Unless you could copy yourself from the atomic level then you are out of luck. An easier way to eternity would be to find out senescence pathways and stop them or reverse them without becoming an instant tumor of yourself.

Uh anon why would I do that? I want to be a kid again. I'll just use my incredible wealth to make an enclave where no one can fuck with me until I am an adult.

I mean surely you can cram an adult brain into an 8 year old skull.

>>9254801
Because you're not the one having the experiences. What OP is proposing is making a clone of yourself and implanting all your memories. But YOU you still die.

I'm pretty much positive there's no moving consciousness from one vessel to another. Think of the brain as a computer, with hard drive, processor etc.

You are the on-state. Even when you sleep your brain doesn't stop working. Even in a coma your brain is still going. It only stops when you die. If you were to die and then get brought back, I doubt it would be you. It would be a different you, a different on-state, working in the same hardware.

At least that's how I see it.

>>9254689
Imagine downloading your brain into a bunch of such bodies, living multiple lives at once and in the end integrating the whole experience into one divine self and becoming that one...

>>9255163
You'd probably go insane from all the conflicting memories. Sensory overload.

The thing about your brain is that it's totally physically isolated from other brains. I know they've planted electrodes in monkey brains and taught the monkeys to use robotic arms, and they could implant electrodes that connect your brain to another brain. Keep increasing the number of connections and you have to ask yourself where "you" are, where your consciousness is because essentially you're no longer and isolated brain but two. Maybe in this way you'll eventually be able to transplant yourself into another, younger brain or something. Or maybe I'm just being a brainlet.

>>9255244
What the fuck are you talking about? From a neuroscientific perspective, what you just said is like trying to teach a child quantum mechanics by literally feeding him books about it

>>9255259
Nah, I think he could be on to something. Imagine two different people who have their optic nerves connected by some sort of neurophys experiment. Call them subject A and subject B.

What if the researchers blindfold subject A while at the same time send a copy of subject B's vision to subject A. Does subject A see what subject B sees?

Could you extend this setup to other parts of the nervous system? Can the experiment send and receive to both subjects such that they share not just sensory information but other information like emotions, forms of memory, motor signals, etc.? Subject A and B are both still separate people, but since they are now sharing alot of information, do they start to feel as if they are both themselves and the other person at the same time?

It reminds me of some research in which two people connected to a neurophys setup could share information about the status of games through a brain-to-brain interface, despite both people being separated by some distance:

You're right nothing could possibly go wrong flooding the brain with a bunch of memories when your body has no memory of doing any of that shit.

I bet you think you can program people to do complex tasks as well.

I'm not reddit; you are.

>>9255429
It's just the fact that you're making statements about a wildly hypothetical situation with nothing to back it up. It's typical redditor larp behavior

>>9254736
>Unless you can clean of aged cells and plaques, otherwise you'd have old age diseases in your teens

Actually when you insert young blood into old mice, their organs rejuvenate. So it is quite feasable that if you somehow manage to insert your old brain into a new young body, it will acquire young brain characteristics.

>>9255436


Then what are you doing in this thread but shitpost in my favourite board?

>>9255445
This isn't /r/futurism you faggot.

>>9254689
No. We are a few hundreds of thousands of years away from that.

>>9255161
In what way is the clone not "you"?

Humans aren't switches. Try to prove your point without using comparisons.

>>9255436
Reddit nigger fuck off pls (see how syntax and semantics diss too?)

Holy shit nugs get back on topic jeez

>>9255470
All I see is you making an even bigger dumbass out of yourself.

>>9254689
i love how for most of human history sex was inevitably asociated with pregnancy and all of culture was shaped by this, and nowadays even tough its no longer true it continues.

i think something similar will happen with biological inmortality. people will have a very hard time grasping that the passing of time is no longer linked to aging and death

Segmentata transferum.

>>9254689

simple answer:

1. remove brain from body
2. keep brain alive in future brain-preservation tank
3. apply special treatment to slowly replace every brain cell with baby-fresh brain cells and replace lost cells
4. put fresh brain into old/new/robot body

>>9255443

problem with the brain is that when you replace a cell it fucks the connections, which is specifically why brains for the most part never regenerate, they just do their best to replace the lost cells with more connections.

>>9254689
>download brain
No. This meme needs to die. The only true form of immortality is one that preserves the brain. All other forms of immortality just allow the future to experience you, they dont allow you to experience the future.

we only use 5% percent of our brains m8 ;^)

this literally the plot of self/less

if you can take a snapshot of the entire brain, down to the molecular level, then import that snapshot to a sufficiently powerful computer and resume time for it, how is that not different than the biological version, only simulated in a computer?

>>9256602
Thats not true. The reason why the brain doesnt regenerate too much is to preserve memories. Also, i never mentioned replacing cells at all, just reverting their age. Its thought that old blood carries molecules that signal aging, and thats why when you replace it with new one, you remove this stimuli.

>>9254689
But George Soros already do it. He just replace his organs constantly with young ones every now and then.

>>9254745
>>9254801
But it doesn't work like that I think. For example, it's know than your consciousness die everytime you sleep and when you wake up again the brain just activate a copy of your consciousness made before you went to sleep and lost it. But I mean, you really don't realize that your consciousness have died thousands of times and you are just a copy of your yesterday self. Please, explain this to me because I really don't understand.

>>9254689
the only way stuff like this works is if you can keep the stream of consciousness

thus you'll have to do a brain transplant (will most likely fail due to rejection) or replace your body parts with Synthetic parts or Stem Cell Rejuvenation

Not to mention your brain ages too

>experiments on mice

why is this shit even a thing in science?? rats are so unbelievably far in terms of physiology and genetics than humans, why not chimpanzees, the closest relative, or even better, criminals/niggers?

Fuck off. I can't even handle my 20 years of life. I wish I only lived to 17.

>>9254715
your body replaces all of it's cells every 7 years anyway so you might as well put all your memories in another body and then kill yourself

>>9254715
>>9257603
Every 7 years every cell in our body gets replaced anyway, does that mean right now you're slowly losing consciousness/dying? NO. what makes us us is our memories that's literally it, not the cells/atoms we're made from.

Life/consciousness is an abstract concept

>>9257476
Are you fucking retarded? When you sleep you're not unconscious your just in a lower state of unconsciousness, hence why noises can wake you up and you can tell time has passed when you wake. To actually be unconscious you need to be in a coma or under anesthesia or something like that.

>>9257951
>lower state of consciousness.
Apparently I'm reataded too

Wouldn't a two way brain computer interface that was sufficiently advanced allow us to fully computerize consciousness? I think at first we will start enhancing our brains with computers and become superhuman. We could transfer emotions, thoughts even experience each other's memories or relive our own. Maybe in the end it would turn out to be kind of a gradual mind upload? You could safekeep your consciousness by storing it in a distributed network.

I'd like to think that even merging consciousnesses and forming a single human/AI hybrid hivemind is not impossible, although the idea makes a lot of people uncomfortable and I'm not sure if I'd want to jump head first into that.

>>9257951
And when you get knocked out in a fight, then your conciouness does really die?

>>9254689
Repeate 100x = bored af. You would end up with killing yourself, OP.
