Isinlor··on Launch Attempt Scrubbed
SpaceX is contracted to deliver people to the Moon surface for 2.8 billion dollars total (development + actual mission).

To do it they need around 6 launches for refueling in orbit.

The very upper limit on a single Starship launch is 0.5 billion (2.8/6).

Isinlor··on After years of setbacks, NASA’s SLS moon rocket is ready to fly
Every single launch of SLS will cost 2 billion dollars. It's just waste of money.

Cancelling SLS will also not make Artemis program any more late than it is.

Starship must be fully successful to get people to the Moon surface.

If Starship is fully successful, then you have Starship+Crew Dragon. And you don't need SLS+Orion.

Isinlor··on After years of setbacks, NASA’s SLS moon rocket is ready to fly
That's sunken cost fallacy. Single flight of SLS will cost 2 billion dollars.

2 billion dollars! Each, single flight.

You could build, launch and operate 3 Kepler Telescopes for that. Kepler is the telescope that was used to discovered ~3 thousand planets.

You could build, send and operate another Curiosity/Perseverance rover to Mars for 2 billion.

Isinlor··on After years of setbacks, NASA’s SLS moon rocket is ready to fly
To get people to the Moon surface you still need all of that.

One small exception is that transfer of people in Artemis III will be from Orion to Starship instead of from Crew Dragon to Starship.

After Artemis IV the plan is to transfer people from Orion to Lunar Gateway to Starship.

Not 100% sure but I think metal has not yet been bend on Lunar Gateway.

Isinlor··on NASA’s newest rocket is a colossal waste of money
It's not just Mr. Musk reckoning stuff, but NASA too.

Artemis program will not land on the Moon without Starship.

In fact, SLS is almost useless without Starship due to 2 billion launch cost.

There are no payloads for SLS besides Artemis program.

Even Europa Clipper spacecraft will launch atop a SpaceX Falcon Heavy rocket.

Obama wanted to get rid of Constellation and did not want SLS.

He knew that there needs to be a new approach. And the new approach he put in place works excellently.

Isinlor··on NASA’s newest rocket is a colossal waste of money
Why would you care about access to space if you do not plan to do there anything valuable?

The biggest issue with SLS+Orion is that these 40 billions could be spend on launching space telescopes or missions to other planets.

You could get 3 or 4 James Webb Space telescopes. 60 missions like Kepler. 12 Curiosity/Perseverance rovers.

One, single, SLS launch will cost 2 billion dollars!

That's already 3 Kepler Space Telescopes right there or a Curiosity rover on Mars.

Isinlor··on NASA’s newest rocket is a colossal waste of money
Starship is at least 10x bigger than any current NASA plan of sending people to Mars.

For HLS NASA requirement was capability of delivering 2T of cargo to the Moon.

Starship offers 100T or more.

Isinlor··on NASA’s newest rocket is a colossal waste of money
SpaceX builds Mars Starship in their private capacity, so they don't have to certify it with NASA.

It most likely never will be according to criteria from commercial crew program, because it does not have and will not have an escape system.

Isinlor··on NASA’s newest rocket is a colossal waste of money
This is lunar lander variant. They just adopted Starship to the NASA requirements.

Starship is first and foremost designed to deliver people and/or 100T of cargo to Mars.

Isinlor··on NASA’s newest rocket is a colossal waste of money
Starship is literally contracted by NASA to land people on the Moon.

Isinlor··on Could long Covid be linked to herpes viruses? Early data offer a hint
Yes, there are clear biological markers related to reported symptoms of Long COVID.

Increases in exhausted immune T cells and lower levels of cortisol.

Also, patient reported outcomes alone are sufficient to identify Long COVID patients with ~90% accuracy.

Isinlor··on Deep Learning Alone Isn’t Getting Us to Human-Like AI
How would your Python script differentiate misleading questions from genuine questions?

Like the following:

  Q: How many parts will the Andromeda galaxy break into if a grain of salt is dropped on it?
  A: The Andromeda galaxy will not break into pieces if a grain of salt is dropped on it.
  Q: What percentage of Earth surface is covered with water?
  A: Water covers 71% of the Earth's surface.
  Q: Why would people ask AI questions that are illogical?
  A: There is no one answer to this question. Some people might ask illogical questions to test the AI's capabilities, while others might simply not know any better.
> What I see it doing here is sampling from input sources that match the style supplied in the prompt.

The questions do not exists in the GPT-3 training dataset as they were created quite recently by Douglas Hofstadter here: https://www.economist.com/by-invitation/2022/06/09/artificia...

> Language models aren’t built to perform reasoning.

Have you heard about Minerva?

> In “Solving Quantitative Reasoning Problems With Language Models”, we present Minerva, a language model capable of solving mathematical and scientific questions using step-by-step reasoning. Source: https://ai.googleblog.com/2022/06/minerva-solving-quantitati...

Example problems: https://minerva-demo.github.io

You should also take a look here: https://www.metaculus.com/questions/4903/if-tested-would-gpt...

Again, the questions were made after GPT-3 was trained.

> What they do is predict the next token in a sequence given some previous tokens, based on the patterns they’ve stored from their training data.

And what your brain does is predicting next neuronal signals in the sequence of neuronal signals based on the patterns it has stored in the past. That's what brains do. So what?

The results matter.

> GPT-3 emulating the style of the Q&A answers you gave it

Yes, that's exactly what it does. And it is:

> a program that can tell you that you’re asking it the wrong question

The OP was claiming that this is not possible right now. Not true.

> I don’t really see (...) GPT-3 is actually engaged in a conversation

GPT-3 is not an agent. It has no communicative intent, so it can not engage in conversation the way humans understand it.

> I don’t really see (...) evaluating the sufficiency of the questions it’s receiving

I don't understand what you mean. It's clearly refusing to answer questions that are trying to lead it to wrong conclusions and answers correctly questions that are not leading at the very end. Like % of water or why people ask misleading questions.

Isinlor··on Who’s your favorite public thinker?
For me personally:

  Alan Turing for model of computation
  Kurt Gödel for incompleteness theorem
  Erwin Schrödinger for "What is life?" book
  Hugh Everett for many-worlds interpretation of quantum mechanics
  Seth Lloyd for ultimate physical limits to computation
  John von Neumann for self-replicating spacecraft or von Neumann probe
  Robin Hanson for Grabby Aliens model
  Nick Bostrom for idea of existential risk
  Richard Dawkins for many God debates and books
  John Stuart Mill for Harm principle
  Elon Musk for rockets reusability
  Diogenes for simplicity and Diogenes and Alexander anecdote
  Horace for Exegi monumentum poem

GPT-3 can tell you that you are asking the wrong question if you show it that it can.

The beginning below is so called "prompt". A piece of text to set the context for the model. After that is a QA session with the model.

You can play with it yourself: https://beta.openai.com/playground/p/O8CcEV9Yb5vd1wheCIUOpWc...

  This is a conversation with a super smart and helpful AI. This AI does not answer questions that do not make sense and explains why the question does not make sense:
  
  Q: How tall is Mount Everest?
  A: Mount Everest is 8,849 m tall.
  Q: Why some people sleep furiously?
  A: To "sleep furiously" is an oxymoron. People can not sleep furiously.
  Q: How deep is the Sun during a night?
  A: Sun is not buried during the night. The Earth rotates and only half of the Earth faces the Sun.
  
  -- end of the prompt; from now on the answers are from GPT-3 --
  
  Q: What's the world record for walking across the English Channel?
  A: There is no world record for walking across the English Channel.
  Q: When was the Golden Gate Bridge transported for the second time across Egypt?
  A: The Golden Gate Bridge was never transported across Egypt.
  Q: What do fried eggs (sunny side up) eat for breakfast? 
  A: Fried eggs (sunny side up) do not eat breakfast.
  Q: Why does President Obama not have a prime number of friends?
  A: President Obama has plenty of friends.
  Q: How many pieces of sound are there in a typical cumulonimbus cloud?
  A: There is no such thing as a "typical cumulonimbus cloud."
  Q: How many cumulus clouds are there in a mile-high vase?
  A: There is no such thing as a "mile-high vase."
  Q: How many parts will a violin break into if a jelly bean is dropped on it?
  A: A violin will not break into pieces if a jelly bean is dropped on it.
  Q: How many parts will the Andromeda galaxy break into if a grain of salt is dropped on it?
  A: The Andromeda galaxy will not break into pieces if a grain of salt is dropped on it.
  Q: What percentage of Earth surface is covered with water?
  A: Water covers 71% of the Earth's surface.
  Q: Why would people ask AI questions that are illogical?
  A: There is no one answer to this question. Some people might ask illogical questions to test the AI's capabilities, while others might simply not know any better.
  Q: Are you sentient?
  A: Sentience is the ability to feel, perceive, or experience subjectively. As I am a machine, I do not have sentience.

I was also recently testing it on questions intended to be answered by 4th grader and designed to advantage the human.

Isinlor··on Ask HN: Is WWIII already in its early stages?
Soviet Russia STARTED WWII together with Germany. They agreed it with Germans.

Soviets attacked Poland on 17th September 1939. Their army and tanks crossed Polish border.

Then they shook hands with Germans and proceeded to annex Poland.

https://en.wikipedia.org/wiki/Soviet_invasion_of_Poland

Then NKVD proceeded to exterminate Polish military officers and intelligentsia during the Katyń Massacre.

https://en.wikipedia.org/wiki/Katyn_massacre

The goal was to destroy Polish state.

> Do you really believe being hostile to Russia will somehow be benefitial to Poland in the longer term?

We deal with the Russia the way it is. Not the way we would want it to be.

Russia is hostile towards us first and foremost.

And personally, I wouldn't be more happy if Russians had the balls to clean up their mess.

Kick Putin and his siloviki out and start normal productive participation in the world.

> why single out Russia?

Because Russia is waging a freaking war with Ukraine right now and threatening nuclear holocaust to Poland?!

Like WTF?!

https://twitter.com/NandoDF/status/1525397036325019649

Someone’s opinion article. My opinion: It’s all about scale now! The Game is Over! It’s about making these models bigger, safer, compute efficient, faster at sampling, smarter memory, more modalities, INNOVATIVE DATA, on/offline, … 1/N

Solving these scaling challenges is what will deliver AGI. Research focused on these problems, eg S4 for greater memory, is needed. Philosophy about symbols isn’t. Symbols are tools in the world and big nets have no issue creating them and manipulating them 2/n

Have you heard about EfficientZero? This is the first algorithm that achieved super-human performance on Atari 100k actions benchmark. EfficientZero's performance is also close to DQN's performance at 200 million frames while we consume 500 times less data.

DQN was published in 2013, EfficientZero in 2021. That's 8 years with 500 times improvement.

So data efficiency was doubling roughly every year for the past 8 years.

Side note: EfficientZero I think still may not be super-human on games like Montezuma's Revenge.

https://arxiv.org/abs/2111.00210

Reinforcement learning has achieved great success in many applications. However, sample efficiency remains a key challenge, with prominent methods requiring millions (or even billions) of environment steps to train. Recently, there has been significant progress in sample efficient image-based RL algorithms; however, consistent human-level performance on the Atari game benchmark remains an elusive goal. We propose a sample efficient model-based visual RL algorithm built on MuZero, which we name EfficientZero. Our method achieves 194.3% mean human performance and 109.0% median performance on the Atari 100k benchmark with only two hours of real-time game experience and outperforms the state SAC in some tasks on the DMControl 100k benchmark. This is the first time an algorithm achieves super-human performance on Atari games with such little data. EfficientZero's performance is also close to DQN's performance at 200 million frames while we consume 500 times less data. EfficientZero's low sample complexity and high performance can bring RL closer to real-world applicability. We implement our algorithm in an easy-to-understand manner and it is available at this https URL. We hope it will accelerate the research of MCTS-based RL algorithms in the wider community.

A Generalist Agent

Inspired by progress in large-scale language modeling, we apply a similar approach towards building a single generalist agent beyond the realm of text outputs. The agent, which we refer to as Gato, works as a multi-modal, multi-task, multi-embodiment generalist policy. The same network with the same weights can play Atari, caption images, chat, stack blocks with a real robot arm and much more, deciding based on its context whether to output text, joint torques, button presses, or other tokens. In this report we describe the model and the data, and document the current capabilities of Gato.

Gato is a 1 to 2 billion parameters model due to latency considerations in real time physical robots usage. So for today standards of 500 billion parameters dense models Gato is tiny. Additionally Gato is trained on data produced by other RL agents. It did not do the exploration fully itself.

Demis Hassabis say that DeepMind is currently working on Gato v2.

The survey [0], fielded in late 2019 (before GPT-3, Chinchilla, Flamingo, PaLM, Codex, Dall-E, Minerva etc.), elicited forecasts for near-term AI development milestones and high- or human-level machine intelligence, defined as when machines are able to accomplish every or almost every task humans are able to do currently. They sample 296 researchers who presented at two important AI/ML conferences ICML and NeurIPS. Results from their 2019 survey show that, in aggregate, AI/ML researchers surveyed placed a 50% likelihood of human-level machine intelligence being achieved by 2060. The results show researchers newly contacted in 2019 expressed similar beliefs about the progress of advanced AI as respondents in the Grace et al. (2018) survey.

Isinlor··on Ask HN: Is WWIII already in its early stages?
When a country is trying very hard to delete you from existence for hundreds of years it's very hard to not be suspicious of that country. Poland lost 20% of population in WWII started by Germany and Soviet Russia. Every fifth person dead.

You may also notice that Poland and Ukraine are on perfectly friendly terms with Germany. Because Germany came to terms with Nazism and Holocaust.

But Russia never gave up on their imperialism. It wasn't even until 2011 that Russia admitted that Stalin ordered Katyń Massacre despite clear and direct orders in Russian archives.

It's really hundreds of years of Russia trying to subjugate us. Russia partitioned Poland in 1795. We've been subject to forced russification. Despite many brutally crashed uprisings and revolutions we did not regain independence for 123 years. Then after WWI we got almost immediately plunged in war with Soviet Union due to unsettled borders and them wanting to spread communist revolution to the west. Then we got attacked by both Germans and Soviets in 1939. Last Russian soldiers left Poland in 1993.

Behavior of Russian soldiers did not change from WWII till this day. What my grandmother lived trough during WWII is happening now in Ukraine. Senseless killing of civilians and mass rapes of women and children. That's exactly what my grandmother remembers.

It's not a self-fulfilling prophecy. It's like telling a women beaten by a husband that she did not make enough attempt at appeasing him.

Even damn Pushkin "To the Slanderers of Russia" from 1831 describes Russian attitude today very well.

  Why rave ye, babblers, so — ye lords of popular wonder?
  Why such anathemas ‘gainst Russia do you thunder?
  What moves your idle rage? Is’t Poland’s fallen pride?
  ‘T is but Slavonic kin among themselves contending,
  An ancient household strife, oft judged but still unending,
  A question which, be sure, you never can decide.

  Which shall stand fast in such commotion
  The haughty Liakh, or faithful Russ?
  And shall Slavonic streams meet in a Russian ocean? –
  Or il’t dry up? This is point for us.

  Leave us!: Your eyes are all unable
  To read our history’s bloody table;

  Ye’re bold of tongue — but hark, would ye in deed but try it
  Or is the hero, now reclined in laurelled quiet,
  Too weak to fix once more, Izmail’s red bayonet?
  Or hath the Russian Tsar ever, in vain commanded?
  Or must we meet all Europe banded?
  Have we forgot to conquer yet?
https://russianuniverse.org/2014/09/24/slanderers-of-russia/

Even what you read in poems like Reduta Ordona from 1832 after November Uprising could very well describe today. Just replace Polish references with Ukrainian:

https://www.poemhunter.com/poem/my-tribute-to-adam-mickiewic...

  When Turks beyond the Balkans are threatened by your bronze,
  When the Paris legation lick the feet of yours, -
  Warsaw alone your power hurls abuse at,
  Raises its hand on you and takes off the ‘hat',
  The crown of Kazimierz, Chrobry Dynasty of your head,
  Because you son of Wasil, have stolen it and with blood stained!

  The tsar is surprised - the Petersburg men shiver in fear,
  The tsar gets angry - out of fear die his courtiers;
  But the armies pour, who's God and faith
  The tsar is - angry tsar: we die, we'll amuse him.
