the human brain just grows more cells and packs them denser when it needs more storage space
and you literally don’t even need to run out of storage space to forget years or decades of your life
all you need to do that is depression or trauma
or brain damage
personally, i think living to 100,000 is rookie numbers
the least i will settle for unless something really bad happens first, is outliving the sun.
and like
there are thousands of things you could do with 1 billion years, much less 100 billion to a few trillion years
for example
make an actual seed world, and document evolution as it happens
build a planet
research how to stop every possible end to the universe
figure out how to create artificial universes that exist in a separate set of dimensions from us, and can only interact with our universe through portals
figure out how to make a computer that can simulate a stronger computer
research how to make a self-running simulation(as in, a simulation that can run a computer with more computation power than the original host computer, and can also use the processor of the computer inside the simulation to run, at the cost of speed)
looks at electrotrophic bacteria, deinococcus radiodurans, and strong electrets(which will be invented within 10-500 years)
looks at high-entropy alloys and plasma barriers
looks at gene editing technology and protein folding algorithms
looks at the genes that cause the neurons that produce dopamine to be more likely to die
looks at the three scribes method of error correction
looks at how tardigrades and deinococcus radiodurans sheild their DNA from damage
looks at the genes that cause high neuroplasticity to be more likely to retain into adulthood
looks at the fact that cells only need a way to recycle enough ATP, nutrient input, and somewhere to put waste products to survive, and not anything that they can’t get from inside a closed system
looks at the genes that cause your metabolism to slow down as you age
looks at telomerase and DNA de-methylation
looks at photonic computing and active danger avoidance systems
looks at how the heat death of the universe is entirely preventable
looks at how you only need to not be where everything else collides to survive the big crunch
they’re literally just misfolded proteins
all you need to do is unfold them or shred them into amino acids and ammonia
and what are the problems you see with having an infinite lifespan?
loneliness?
just make other people immortal with you
you have literally all the time in the universe to find them.[quote=“aah31415, post:8238, topic:5842, full:true”]
Pretty sure human brains still have a max capacity as to how much they can remember. After a few thousand years or so it wouldn’t be surprising if you began forgetting whole years if not decades of your life.
[/quote]
boredom?
make some seed worlds
learn to code
figure out how to simulate a universe that runs faster than our own
invent new types of exotic life
find new games to play, there are literally infinite possible computer games
disease?
just cure it. as long as it’s not deadly, you have all the time in the universe
if it is deadly, you have until it kills you
and if you can’t cure it, use it as an excuse to upgrade yourself
for example, if it’s brain cancer, grow your brain with neurons that have a completely custom built genome, and compute or at least communicate with light, and then wean your consciousness off of your human brain, by slowly decreasing the energy your human brain bits receive.
if you notice something going wrong, you can just increase its energy budget again, and find out what went wrong, so you can fix it
and that’s the hardest one you can do, aside from killing off an autoimmune disease, which takes killing off your immune system
why would going insane be a reason to end your life?
being sane is boooring!!
having some of your screws loose, some missing, and a few hanging on by the edges of their threads is fun!
and makes you fun to be around!
i already do that
and due to how belgiumed up my sense of scale gets when it comes to time, i doubt that how much i do it will change at all if i become functionally immortal
like, a temporary afterlife? or a way to just temporarily go back into the void you lived in before you were born, but for a longer time period than sleep lets you?
there really isn’t one except your skull
the thing about the human brain having finite capacity was proven false a while ago
mainly due to 2 things
how memories are formed, and how you do actually produce neurons after your brain finishes expanding
long-term memories are formed by creating or reinforcing axons, using medium-term memory
medium term memory is formed by processing the information in your working memory, which is an effortless process that only requires you set aside some time where you aren’t thinking or processing too much stimuli
short-term memory is formed by taking in stimuli or thinking
and neurogenesis was confirmed to continue up until your neuron progenitor stem cells run out of telomeres, which is when dementia starts kicking in if you’re predisposed to it
and if it didn’t continue past childhood, adults would be nearly incapable of healing or recovering from even moderate brain damage without stem cell therapy.
and, if you take telomere shortening out of the equation, the brain grows denser as you age, and gets more and more powerful, until it simply can’t get denser
which means you just need to take it out of your skull, and put it in a larger container
and if that isn’t enough, upgrade the cells of your brain
make each cell be a ganglion
give each cell a brain made out of prokaryotes that have the sole purpose of acting as neurons do, but that communicate using insulated nanowires, rather than action potentials
make your neurons be 1-2 um long, and make their host cells communicate with bundles of optical fibers
and that lets you have electrical gangliocytes be able to directly communicate with optical neurons
or, even better, photonic gangliocytes, since gold nanospheres and SiO2 nanospheres can get down to 10 nm, and there’s no reason you can’t do multilayered computing
and it’d be pretty belgiuming easy to make an enzyme that uses a specialized type of non-encoding DNA to store the instructions to make different structures
