The Fermi Paradox, the big question of where all the aliens are, has many proposed solutions focusing on what might lower the odds of intelligent species arising on another world, or what might end technological civilizations or cause them to go unseen by us and our SETI efforts. But what if intelligence rarely leads to technological civilizations in the first place? Could there be countless planets in our galaxy occupied by species who never came to value technology?

You made me think of a filter I haven't heard of before. An all-in society (the opposite of a technologically skeptical society). We appreciate and practice outdated technologies and skills. Imagine a society that developed a new food, for exsmple, and decided to consume only it (example: bread). If that new technology becomes a limiting factor, it may damage or possibly destroy a society. If a solar flare wiped out all our electronics, we would survive as a species because we have enough people who practice obsolete technologies that don't rely on electricity. By appreciating, teaching, and practicing obsolete technologies and traditions, we have developed a buffer to an all-in killer.

You mentioned agricultural and the hard choice to plant some of your food so you may have more in a few months. How hard that was was even harder when they found you needed to plant the best part of your crop, and eat the not so good stuff, to have more of a good crop later. That seems to me an even harder choice to make.

@@mrs7195 even though there's a large amount of the universe's history where life as we know it is all but impossible the fact is that there's still plenty of time behind us for life like us to have evolved thousands of times over. It was a specific set of circumstances that has brought us to where we are now, if any number of minor things happened differently in our worlds past we could easily be a thousand years into traveling the stars, or one of any number of other animals could have made the climb to sapiency. If we assume that a large number of the closest million stars have had the same amount of time for events to play out it's still a question as to why one or more of those stars hasn't spawned an obvious stellar civilization. Remember, in the course of only a few hundred years we advanced from technology that was only slightly changed over that of the Greek city states to what we have now. If the political and social environment had been a bit different a few thousand years ago we would have been primed for something like the industrial and technological revolutions that define our modern world and in the intervening centuries we could easily have a robust space economy and people living outside of our solar system even assuming technology capped out at what we can see as being possible today.

Things could be different, but things aren't, one thousand years, in cosmic scale is nothing, so if things could happen sonner or later, between centurys, that was irrelevant, in the cosmic scale, they will happen in the same way, things really start to change after a million years or more, that is the time that we will probably will be able to spot an advanced civilization in this galaxy. As civilization, we are very young, humanity is around this world for 7 million year, if things could happen 100 hundred thousand years ago, we will probably be reaching some closest stars by now, but even at this point, we couldn't be easily spoted to anyone looking at this stars, like we look at them right now. So, they are either more or less at same level that us, or they are far advance that we could spot them everywhere we look. Since we never notice anything like it so far, or we are early, or they still don't have enough influence that we can notice them.

Note about the marshmallow experiment: The kids that were the most about to delay gratification were from wealthier families. This means that kids who experienced food scarcity were less likely to believe that there would be more marshmallows in the future and likely feared missing the opportunity to eat any. Whereas the kids who didn't experience for scarcity were less worried about missing the opportunity to eat a marshmallow and more likely to believe the promise of future marshmallows. Also the income of the family is more of an indicator of both future success for the child as well as being an indicator of how well the child will be able to delay gratification.

Looking at Earth, rare technology seems to be a pretty good filter. Life seemed to arise pretty much as early as it was possible, after which the jump to multicellular life took a long time (seems a decent filter too). Once multicellular life arose, it seemed to diversify a lot. There appear to be a lot of decently intelligent species on Earth (corvids, parrots, apes, cephalopods, ceteceans, elephants, ...), some of which use primitive tools (sharpened sticks, brushes made out of sticks, ...). Only humans seem to have developed truly complex tools though.

This is where I disagree with the video. While our disgust reflex is strong, the _things_ we react to are typically not very fixed. "Spit and polish" was meant literally. You put a final clean on metal, ceramic, and smoothed wood items, including cutlery and crockery, by gobbing on them and rubbing it in. Even many of Isaac's own examples of things we did in the past are things we find disgusting today, but were not only commonplace, but necessary to our survival and advancement. Carrying water inside an animal's stomach. Proper sausages (offal inside an intestine). Even just wearing animal skins... you preserve hides by urinating on them, otherwise they will rot. It's only fairly recently that leather tanners were able to stop buying human and animal urine to supply their industry. How about using faeces to fertilise fields? An essential part of agriculture for most of history. Disgust is highly mutable and adaptable. We have to learn what to find disgusting. Our fear of spit is, IMO, purely a learned response following the introduction of advanced hygiene following the Germ Theory of Disease. An entirely modern phenomena.

I'm reminded of the issues with Neanderthals, and how despite being bigger, stronger, and smarter, they didn't succeed. Being bigger, and with big brains, they were costly to feed, so had smaller social groups, and were less productive in technology and specialization as a result. And being strong enough to run up with a spear and exchange blows with even bigger creatures and survive (even if injured in the end, still surviving), they didn't have as much incentive to develop better ranged weapons and tools like the atlatl. Then when the climate changed and food sources changed, their specialization of hunting big game failed and started to lead to some serious problems. Lots of cases where you can be "too good" in some aspect to need technology to cover for the weakness, and thus not develop technology to adapt to stuff, until the environment changes too much and it's too late. Taking it to an extreme, imagine a dragon, the smart kind. Big, apex predator, thick scales nothing else can really scratch, unmatched strength and offensive power, good mobility, overall just a creature that can survive almost anywhere and against anything without issue. Not much reason for them to start developing early technologies when they are much better than anything they might make would be. Figuring out how to make a comfy, fluffy or shiny nest, or dig out a nice cave to avoid snow or something might be as far as it goes even if they are insanely intelligent creatures. Humans started as tree dwellers, pushed out of our preferred environment do to environmental changes, and forced into some very dangerous changes that in the end we did survive, but were not too far from wiping us out. We survived only barely, in part do to our intelligence but also a bit of luck and various other key traits. But we were still badly enough suited for our new environment that we had incentive to come up with tools to help us, clothing to protect us, and fire to cook (something we probably wouldn't have done had we still been living in trees mostly). Quite simply, it's a MASSIVE number of coincidences and lucky/unlucky happenings that came together to create humans, propell us to create and use tools and technology, and to not die in the process.

at least so far as we know..i mean, its hard to have a control group and test group...when theres only 1 group on the planet. Plus, there may have been other factors in the decline of the neanderthal that we are not aware of. Anyway, its hard to fathom how and why at this point in time.
@squirlmy
@squirlmy 4 года назад
Your example of Neanderthals is total BS. There's not a falsifiable statement in there. It could be that homo sapiens overwhelmed them numerically, just as they were, without "advanced" weaponry or any special trait. Remember too, that most modern humans are 2-3% Neanderthals, so they DID succeed: theories of their decline have to be made relative to "pure" homo sapiens, not to extinction. The dragon example is a more solid point, but you could've even kept to primates and talked about gorillas, or any big mammal predator, but whatever... In the final example, "we survived only barely, in part due to our intelligence": while it's reasonable enough to guess intelligence helped, again you're stating it as fact when we don't know. It even in contradicts the last statement; sheer luck might have been much more of a factor in our survival than intelligence ever was. After all, it only seemed to make a big difference in the past few thousand years, out of at least 200,000. You're much too impressed with your own theories about what did and didn't happen to early humanoids. Get a grip on what there is evidence for, and when your fanciful theories are just that, instead feeding your ego with your own cleverness.

The only problem is that even if our technology is rare, that won't be an answer to the fermi paradox. It's just hard to imagine it being so rare that it's only happened once, here on earth.
@terricon4
@terricon4 3 года назад
@@EmmaDilemma039 The point I was trying to get across was that just because you have inteligence doesn't mean you develop advanced technology, and that it's by any means a sure fire way to survive early on either. So it's just another one of those chances, to add in to the total stack of odds against technologically advanced life. First, what are the odds for life, complex life, and everything else? We honestly don't know. Then the odds for intelligent life, as we saw it took ages for the dinosaurs to die off and give us a chance for some intelligence builds on earth. And then even if inteligence comes around as a higher focus, the odds of it turning into technology wielding species seems like it could be quite low, first does said species have the ability to work with tools, can they use fire in their enviornment? Do they even have a need to start making and learning stuff (the dragon and partially the Neanderthal example I previously gave), and then even if they do have the need and see the benefit, is that going to be enough to make sure they don't die out from other changes? These aren't ever an excuse on their own, it's just about stacking the odds. Each time you lower the odds with another one of these steps/barriers, it is on top of all the previous ones, an exponential increase in difficulty for that one final goal to happen. For all we know life itself might be super insanely rare to start, or yes, it could be on millions of worlds out there, but inteligent life might just rarley ever get the chance over brute force, now a few thousand worlds, and of those maybe only a hundred had hands and safe enviornments to use fire and develop tools with. And then of those only a few survived incliment weather or other changes to their enviornment or predators with changing times. And of these few dozen left maybe only a couple who managed to previously survive were still weeke nough to really develop their technology very far within a million or so years. And now of these not yet one of them has survived the baking of their planet after they started breaking their ecosystems with advanced tech... (us included, not yet at least). This is the whole point, each one o these barriers with unkown actual odds, is still a possible barrier that stacks on the others resulting in that exponential decrease in the odds of something happening. So, it's not that "our technology is rare" that would explain the fermi paradox. It's that life itself that can make technology like ours for communication is rare, that could explain it. At any part in that chain, weather its the first of making life, the medium of having inteligence, or the later of making advanced technology, the issue can be at any of those steps and until we get out and explore our galaxy, kinda hard to really know what any of these different situations odds really are. We might find that life is a one in a billion worlds thing, or maybe its like every other star system has some bacteria. We just don't know so it's just guessing, but small changes in each of these can easily stack into having only 1 technologically advanced species in billions of worlds or so, throw in one or two more barriers, and that's trillions of worlds just like that quite possibly even at just a one in thousand odds each or so. We don't know, and I"m not claiming too, I was just putting forward some ideas on possible barriers some people might not think of. They won't explain it on its own, it's just that they are on more possible thing to stack into the giant list of possible barriers that may or may not explain the fermi paradox.

Stuff like that could present a significant hurdle. Some evidence of that in human history even, although trade and things like colonialism got past that and saw that useful things would see more distribution.

From Climate Stability and the Origin of Agriculture. "The relationship between climate and the development of agriculture has been widely discussed for many years by both the anthropology and climate scientific communities. Many competing views have been developed primarily based on studies of the archeology of the Near East (for a review see [4]). For example, it had been suggested [5] that agriculture appeared as a result of technological advances that gradually increased man’s ability to exploit the environment after man had occupied vast areas of the Earth. Certain conditions were found necessary for the development of agriculture [4] such as the technology for collection, processing, and storage of agricultural products and the presence of potential domesticates in the local environment. Examples included development of improved hunting technology by one group and perhaps experimentation with agriculture by another. The increased efficiency of hunting failed as a survival technique, but the experimenting with agriculture may have had more success, and when the stresses of the YD were removed, agricultural development was accelerated. Bar-Yosef [6] emphasized that the initiating event in this view was a response to the environmental stress during the YD. This same idea has been applied to the development of agriculture in China [7]."
