I think the harsh conditions in Australia, where there a thousand ways to die, put the onus on truth and preservation of it in the oral tradition. Unlike most other cultures where it's kind of ok to gradually deviate from the truth. It is worth paying attention to the aborigine stories.They have also made astronomical observations that are pretty accurate to the date. https://cosmosmagazine.com/space/australias-indigenous-peopl...

Singing/Ballads are also popular way of preserving information fidelity. Homer's works were based on ballads. We don't put premium on memory now, but before the invention of printing press, memory techniques were widely studied and used.


It kind of feels like a local optima situation where they relied on memory so much that they didn't feel the need for writing. Either that or the fact that there was no writing for so long resulted in them specialising in memory techniques a lot.


We didn't evolve reading and writing. Literacy is just a recently developed hack. Memorization was the only way for the vast majority of human history.


Who is we?


But are they different because of the infection, or they are different and hence the infection. That is the question


Aurora magic is possible only because of computational photography. There is no way a phone camera, at the base level, can see more than an eye.


Why do you say that? Or do you call long exposures computational?


They are not long exposures. If they are, you would see star trails, because earth is spinning.


Rather depends upon what you consider "long" to mean. The sun moves about 15 degrees per hour and the angular field of view on a zoomed iPhone 13 shot is about 23 degrees (according to a blog). 12MP resolution so crudely moves about one pixel per second. A ten second exposure is certainly long compared to the light gathering drive by the eye, but a ten pixel elongation of the blob of a bright star won't be very obvious, may be rather less than the smearing caused by atmospheric "seeing"


Whoa, you're just way off base here. You can take a long exposure and avoid star trails depending on a couple of factors, primarily the focal length of the lens. The longer the lens, the less time it takes to start seeing trails. The wider the lens, the longer you can take. I've taken up to 45s exposures with a 20mm lens on a DSLR with no trails. Since most lenses on camera phones are typically wider angle, the limiting factor is having a support to hold it for longer exposures.


Some sources (https://lweb.cfa.harvard.edu/webscope/activities/pdfs/eyeTel..., page 7) say the human eye's "exposure time" is around 1/15th of a second. So a 1 second exposure is 15 times longer and won't see star trails, at least not at normal zoom levels.


You absolutely see star trails on iphone night mode photos when setting exposure to 10s or more. For aurora, 10s is way too much though, 1-3s seems right and is what the iphone allows to do when not on a stable surface or tripod.


Each stone weighed 25 tons.


> Each stone weighed 25 tons.

There was a guy who rebuilt a section of Stonehenge using only techniques that could have been used thousands of years ago, and explained how it was possible to build it.

I'm not sure why people think it's impossible just because they were large and heavy, we see all sorts of other prehistoric things requiring similar effort and modern scientists have replicated the steps necessary. You can move a lot of weight if you have thousands of people involved doing the work.


That reminds me of the various tug-of-war contests around the world where the contestants manage to snap impossibly thick ropes. E.g.

> The 1,600 participants exerted over 180,000 pounds of force on a 2-inch thick nylon rope designed to withstand only 57,000 pounds. Amidst cheers, the rope violently snapped; the sheer rebounding force tore off the left arm of the first man on each side. [1]

Idk, because people are unbelievably not bright. Like humans have hardly evolved in last 200k years, yet, we have made most of the time we had only in the last 500 years. Wheel was "only" invented 6000 years ago. We are only slightly above natural selection in selecting what works. Newton was the first guy to use averages in experimental results - and look at all the brilliant people before him! Socrates, and I am fan, thought writing things down makes people lazy, democracy is a stupid etc - he is arguably one of our finest, and had awesome arguments to back his assertions, yet, he didn't know what works. People only learn through practice, mistakes and improvement. The rest is bogus 99.9% of time. This is why I think we are only slightly above natural selection.


People in general aren't that bright, but we're essentially the same build now as they were back then, there is no reason to assume they didn't have any geniuses.


Don't forget that the world population has been exploding. We have a lot more "bogus" in the world now.


So? With (for instance) this simple & ancient technology -

https://en.wikipedia.org/wiki/Slipway#Slipways_in_ship_const...

- people can routinely construct ships weighing ~1000X the weight that any one worker (or crane) could lift.


To be clear, it wasn't Anglo saxons nor the Celts nor the steppe invaders before them who built the Stonehenge, though some of their DNA survives in the current population. https://www.bbc.com/news/science-environment-47938188


> The ancestors of the people who built Stonehenge

> the Neolithic migrants to Britain appear to have introduced the tradition of building monuments using large stones known as megaliths.

I mean, OK, yes, but Stonehenge was built in multiple phases by different groups of people over centuries. These farming migrants with Eastern Mediterranean grandparents built phases I and II, which had small stones (the bluestones from Wales, initially placed as grave markers before being moved around a lot) and lots of wooden posts.

The impressive phase with the sarsens, the big stones people picture if you say "picture Stonehenge", is Stonehenge III, and that was built by Beaker People, the steppe invaders. Inspired from the culture of their predecessors, I guess, but maybe for completely different purposes, in so far as any of it had a purpose.

The sarsens were connected at the top with woodworking joints, BTW, as if there was a risk they might fall off without pegs to hold them in place. I've never been sure what to make of that, but my best guess is "tradition". (A previous guess was "everybody in prehistory was drunk".)


Or it could be alien made. Like a dyson sphere - but a planet, with solar capture on the shell. Build everything without all the mass, add magnetic shoes and other tech to make living in 0g a reality.


Dang. Didn't know this was a thing. Thank you!



Most people don't want to buy from someone they don't like - I mean this is where cult worship and brand image are important. It is not for no reason Forbes creates a list of most valuable brands every year https://www.forbes.com/powerful-brands/list/

Other way to look at it is, would you care if the seller employs child labor, slavery etc?


I’m happy to pay $99/month for this product. Been driving it last 2 weeks and don’t want to go back to AP. It makes mistakes, sure, but it is predictable. I can chill out in the car with 2.5 hr commute 3 days/week


This is not a legally approved FSD. Elon never bothered to get it certified in some safety lab. There are currently 200-300 court cases where a Tesla has caused injury or damage to property:

https://en.m.wikipedia.org/wiki/List_of_lawsuits_involving_T....

The point is, if it makes a mistake and kills someone, _you_ will end up in jail.

Does this look like chill to you? https://twitter.com/TaylorOgan/status/1542552674880704515


That's an old video from 2 years ago. FSD changed a lot in the mean time. I would agree with you then, and I had the car for 4 years now, and I am only planning to subscribe because it seems dependable enough. I am aware it is not scientific and I won't let of the steering wheel until it is. Nevertheless I can be half present in most of the circumstances. Unless it is a busy, tight street it won't matter to me, because all I am doing is commute on the interstate with lane switching for the most part.
