I thought /ratanon/ might be interested in this, it's a new HN-style link-aggregator exclusively for academic papers, with features such as subscribing to certain tags via rss, etc.

http://paperkast.com/

The community is very small atm. and doesn't have a lot of discussion, but that's why I'm sharing it, in hope it finds some appeal under fellow academics.

Stealing from the tip jar seems like a plausible lapse if one is sufficiently sleep-deprived. Immortalizing the mortification in a blog post seems more puzzling. But what I _really_ want to know is why Aaronson decided to move from MIT to Texas, of all places—that decision really baffles me.

> It’s hard to overstate how unprecedented that is: The president of the United States just directed the secretary of state to look into a racist conspiracy theory he saw on Fox News — a conspiracy theory that is a major talking point for white nationalists and neo-Nazis.

> Whether or not it’s actually true is irrelevant.

What the fuck is happening to journalism ?

Alright, I looked it up.
https://www.vox.com/policy-and-politics/2018/8/23/17772056/south-africa-trump-tweet-afriforum-white-farmers-violence
Half the article is spent explaining that it definitely isn't true. It doesn't leave open the possibility of it being true.
Then it says that Trump has agencies at his command that could give him accurate information on demand, to make informed decisions.
It combines those two things to argue that Trump must have immediately directed the secretary of state to look into it, and made a public announcement, without making sure it's true.
Only then, at the very end, does it use the two paragraphs you quoted to say that that course of action is bad in general.
Poor wording, definitely, but not nearly as objectionable in context. They didn't put this part at the start of the article either, so it's not the usual headline-style motte-bailey switcharoo.

I initially wrote a gigantic shitpost of a reply but I deleted it.
The ending part which I posted doesn't add anything to the article and it makes absolutely no sense. It's even worse in context.
> wow let me just treat this subject and then say it's irrelevant if it is actually true or not even though I said it's not true because Trump saw it on TV on a channel that didn't shit on him non-stop during the elections.

The writer is just retarded and should be fucking fired but we are living in the age of journalism soft shitposting so maybe it's just bait.

No. On cosmological timescales the time between a technological civilization arising and them conquering the galaxy is essentially an instant. Detection through broadcast is just a red herring. The existence of isolated technological civilizations just happening to come into being at the same time as us is extremely improbable.



There is some discussion at https://space.stackexchange.com/questions/17765/from-how-far-away-could-our-seti-searches-detect-and-recognize-our-technological .

Apparently, we do not yet have big enough radio telescopes to detect "leaking" Earth-like radio signals from another planet, so SETI  hoped to discover an intensional signal. For example, many early SETI efforts searched for a radio signal around the "water hole" frequency, hoping that would be a Schelling point for trying to communicate with aliens.

But the great filter problem is not just about Earth-like civilizations. Fermi thought that technological civilizations should quickly become big enough to settle entire galaxies, so then the "great filter" is whatever prevents that—just inverse-square radio signals is not an explanation for that.

> Being "internet famous" has mostly brought me grief online, but in real life it's been a really good supplement to my lack of sociability. Some people who know me online seek me out and pre-emptively like me, which is a useful counter to my reluctance to go out in social situations and do the usual dance of things that help me get to know people and seem likeable.
Now I want to be internet famous.

If something gets assembled that will on average reproduce more often than it will die, then you can get more of that thing, possibly exponentially so.
Most things that were in principle capable of replicating may not have made that bar, and did immediately die. But it only takes one.

> This means clumps of atoms surrounded by a bath at some temperature, like the atmosphere or the ocean, should tend over time to arrange themselves to resonate better and better with the sources of mechanical, electromagnetic or chemical work in their environments
If the theory behind this is correct, it would probably rather lead to minerals forming that absorb a lot of light.
(There certainly is an *evolutionary* advantage to being an efficient heat engine, i.e. absorb sunlight and radiate excessive heat efficiently, so one wouldn't need any new physics to explain what self-replicators tend to look like, once they are around.)
It is very much possible btw that Earth is one of very few planets in the universe to develop life at all. Emergence of self-replicators might therefore not be a once-in-ten-billion-years-per-planet-surface event, but might be billions of times more rare.
