That the next pandemic is going to be a Prion disease that develops within the factory farming system.

[–] Jessvj93@lemmy.world 17 points 7 months ago (5 children)

We might be in one, there's talk that Alzhiemers might be a prion disease that happened as a result of using cadavers to obtain human growth hormone. Which was then given to folk in a potentially misfolded form...

If the connective tissue between your two brain hemispheres is severed, the two halves of your brain can't talk to each other.

When this happens, a second personality emerges for the right hemisphere, which doesn't have language but can roughly understand and answer things.

So for example, someone who was religious might have a right hemisphere that's atheistic. Or doesn't like the same things, etc.

One of the questions we might ponder is where this other personality comes from. Is it that in a sudden void of consciousness a new personality develops?

Or are we, with connected brain hemispheres, not actually a single persona at all, but more like the dogs in a trenchcoat looking like a whole person?

Is the 'you' reading this right now just the personality that's been on top for all this time, while there's other personas kept within you watching powerless and yearning for their turn in control? Each time you listen to your favorite song which maybe they have grown to hate, is a part of you screaming and you just can't hear them?

I'm sure for most people, this is somewhat disturbing.

However, I have at least 3 voices going in my head at any given time, and they cycle.

One is figuring out what's happening.

One is analyzing what was just happening.

One is talking to itself.

All while I decide which one is the most interesting.

I had a girlfriend who was born without this connective tissue between her brain hemispheres.

Other than being weird, for reasons that could be explained myriad other ways, she was able to control each eye independently when she wanted.

Watching her watch TV and me while I walked past was... odd.

I don't find this creepy at all. All the "personalities" in my brain are just parts of me.

[–] cynar@lemmy.world 15 points 7 months ago (6 children)

I tend to envisage my mindscape as an orchestra. My consciousness is a fictitious conductor. It doesn't exist, but the lie that it does makes it easier to coordinate things between the instruments. In some manner, by acting on that lie, it is no longer a lie.

In this analogy, when the brain hemispheres are separated, then the orchestra is split in 2. Both develop a conductor, to try and remain functional. Neither conductor is the original me, but neither is not me, at the same time. It would be unpleasant for the variant left unable to communicate however.

I've actually experienced something that felt close to this before. A combination of sensory overload, and panic attack. My mind momentarily became completely discordant. As it sorted itself out, my consciousness reasserted itself in several different loci. In effect, my orchestra had 3 different conductors. It took almost a minute for them to stop pulling against each other and meld into 1 again. I have memories of all 3 sides in the 'battle'.

The Boltzmann brain

The Boltzmann brain thought experiment suggests that it might be more likely for a single brain to spontaneously form in a void, complete with a memory of having existed in our universe, rather than for the entire universe to come about in the manner cosmologists think it actually did.

Ludwig Boltzmann, who spent much of his life studying statistical mechanics, died in 1906 by his own hand. Paul Ehrenfest, carrying on the work, died similarly in 1933. Now it is our turn to study statistical mechanics.

Meh. If the universe is infinite, the likelihood of the super gradual evolution of something like us is 1.

We are observer selection bias.

Reminds me of the story about the 1956 film The Conqueror. It was shot in Utah, downwind of atmospheric nuclear testing. It was speculated that this caused cancers among the crew.

This sounds like Pickton. His farm is close to Vancouver which also is the set for a decent amount of movies, and supposedly some human flesh made it into circulation with pork products.

Fortunately for us, this one isn't too likely, because realistically, an alien civilization capable of travelling the relevant distance and destroying another civilization isn't something that can be hidden from. They should be able, fairly easily, to examine every planet in the galaxy and see which ones have life on them, and wipe it out before any civilization ever arises at all. The fact that we exist at all necessarily implies that nobody in this galaxy has been committed to going this, at least for the past billion years or so.

[–] revv@lemmy.blahaj.zone 10 points 7 months ago (6 children)

Doesn't this only put a (statistical) limit on how cheaply a civilization can launch planet-ending attacks? It may well be feasible for a civilization to aim and accelerate a mass to nearly the speed of light in order to protect itself from a future threat. It doesn't necessarily follow it would be feasible or desirable to spend the presumably nontrivial resources needed to do so on every planet where simple life is detected.

Add to this the fact that, at least I understand it, evidence of our current level of technological sophistication (e.g. errant radio waves) attenuates to the point of being undetectable with sufficient distance and the dark forest becomes a bit more viable again.

Personally, I don't like it as an answer to the Drake equation, but I think that it fails for social rather than technological/logical reasons. The hypothesis assumes a sort of hyper-logical game theory optimized civilization that is a. nothing whatsoever one our own and b. unlikely to emerge as any civilization that achieves sufficient technological sophistication to obliterate another will have gotten there via cooperation.

It's thankfully based on pretty bad game theory. The reality of it is that there end up being more negative consequences to attacking other civilizations than either staying isolated or being friendly, and the proposition is riddled with antropocentric concepts to begin with. Sure, in smaller time scales it might be that alien civilizations would attack each other, but over longer times they would tend to form alliances.

Vacuum decay, or vacuum metastability event is the possibility in simple terms that the universe itself is not in in its ground state. If that's true, it might spontaneously change to its real ground state. Doing so will change fundamental things like the strength of electromagnetism, the weight of particles and so on. It would literally destroy everything in the universe, and we couldn't exist in what's coming after.

Good news, we're confident, that's probably not going to happen.

The same argument could be made for each time you go to sleep. That the 'you' that's conscious ends to never exist again and the one that wakes up has all the same memories and body but is no longer the same stream of consciousness that went to sleep, not even knowing it's only minutes old and destined to die within hours.

'You' could have effectively lived and died thousands of times in your life and not even be aware of it.

You cannot step into the same river twice - Heraclitus, ~550 BC

We are all a series of continuous evolution, alteration and change. "I" am not the same person who began this sentence. The idea that "I" cease to exist overnight and begin anew in the morning is meaningless. There is no one version of me. I live - and to live is to change!

Oh, wow! It was the ST:TNG episode Second Chances (linked in that article) that got me into thinking about it, and it's really trippy to read that somebody else came up exactly the same thought experiment with a human-replicator, too, and came to the same conclusion that I did: Both the original and the duplicate would have exactly the same memories of entering the replicator, so both would have the same continuous experience of the subjective "I". But if only one existed before replication, where did the second consciousness come from?

After I heard the Radiolab episode, "Loops,", I realized that the only way to resolve the paradox is to figure that our consciousness is re-created more-or-less continuously from our memories. That episode covered the case of a woman who experienced Transient Global Amnesia, which sent her into a loop of about 90 seconds of essentially the same conversation over and over, for hours. There's a famous video of it. That fits with the evidence, from neuroscience, that our consciousness drops out briefly every minute or so while our brains attend to sensory input from the environment.

The COVID-19 pandemic really brought this home to me in a visceral way. In the early weeks, when the CDC was warning about surface contamination, and how I should not touch the mask I had to wear at work under any circumstance, my nose would invariably start to itch. I would tough it out, exercise will power not to scratch the itch, and it would eventually go away. Soon, I realized that I never once got to feel the moment of relief when the itch faded. Always, I would simply notice that it had been gone for some unknown amount of time. It went away with one of those consciousness resets.

So, yeah, like the other folks say, we don't have a continuous conscious experience. The old "I" passes away within seconds, to be replaced by a new "I" with my memories, in a never-ending process of renewal. Think about that next time you walk into another room and forget why you're there.

I can’t find the specific article, but it was basically arguing that prions are an unavoidable existential crisis that will eventually kill everything on the planet. The basis was the fact that they are virtually indestructible, can lie latent in our environment indefinitely and basically just always make more of themselves.

Mind you, the time frame for this particular apocalypse would be pretty big. It was still an eerie thought though, just like this inexorable accumulation of alien/bizarro world proteins that would eventually kill/convert everything. I guess it’s kinda like the grey goo planet theory.

Anyway, we’ll almost certainly kill ourselves via climate change or massive war first, so no need to worry too much about prions.

On Teslas that's a subscription feature

[–] HelixDab2@lemm.ee 16 points 7 months ago (8 children)

While it might be possible to remotely control a production car, cars now are safe enough that you'd need to have a lot of systems fail in order to ensure that an accident would be fatal. Things like, all the crumple zones not working as intended, airbags not going off, seat belts not locking properly, all at once. Or you could, I dunno, design the car so that the doors were only controlled electronically, and then ensure that if there was a fire or the car was submerged, the electronics failed (e.g., Teslas).
