upwardbound··on All possible plots by major authors (2020)
Nick Cole, continued:

Epigraph: Wherever in the universe one happens to find them, an old battlefield, a forgotten glade, buried deep in the rubble of a dead and beam-ravaged world, the graves of Strange Company are often marked such: “Strangers to the Universe, Brothers to the End.”

upwardbound··on All possible plots by major authors (2020)
Because I hope that more people listen to the audiobook series Strange Company:

Nick Cole:

Log Keeper's Note: Aftermath. In those dark years of the long crossing between the world we'd cut loose of the bad contract on, and the repair facility on Hardrock, the Strange Company slept and the galaxy caught fire as we dreamed for twenty-five years of sublight. The old order of the Monarchs, mighty yet petty gods determined to burn worlds and take humanity with them down into the deep dark graves of empire, began its final collapse. Worlds fell into shadowy chaos, overrun by the cackle of automatic weapons carried by the Simia Legions, while ring stations at Oberon and Circe burned like fiery jewels. Into this madness and maelstrom rode the Strange Company.

(That’s a slightly abridged excerpt from the second audiobook of the duology, Voodoo Warfare. I call them audiobooks rather than novels because in print form they are merely quite good but very derivative examples of their genre, but as narrated by Christopher Ryan Grant, they are among the most epic and inspiring stories I have ever heard come alive.)

I think it is the case here, and I hope Elon Musk persists in his lawsuits about this. As a large donor to the nonprofit in its early days he’s one of the people with the strongest standing to sue / strongest claim for damages.

Obviously Elon is mostly doing this suit as a way to benefit Grok AI but honestly I don’t mind that; competitors are supposed to keep each other in check, and this is a good and proper way for companies to provide checks & balances to each others’ power and it’s one reason why monopolies are bad is the absence of competitor-enforced accountability.

Does that amount to making a false forward-looking financial statement? (Specifically his claim that he wasn’t interested in getting equity in the future.)

This claim he made was likely helpful in ensuring the OpenAI team’s willingness to bring him back after he was temporarily ousted by the board last year for alleged governance issues. (Basically: “don’t worry about me guys, I’m in this for the mission, not personal enrichment”)

Since his claim likely helped him get re-hired, he can’t claim it was immaterial.

I really hope someone from the SEC scrutinizes him someday. The Singularity is too important to let it be run by someone with questionable ethics.

I fully agree that users flagged it. What I would appreciate would be if you can please check the data to see if there is a small group of users who consistently flag all negative things about Sam Altman. I suspect the answer is yes.

It is not a throwaway snarky comment, it is an explanation by Yishan and Sam of how they hijacked control of a team away from Condé Nast using a similar playbook as Sam is using in recent years + now to seize control of OpenAI.

This is not about celebrities and I have zero interest in celebrity news. This is about ensuring legal and transparent governance of the nonprofit OpenAI which is among the most likely teams in the world to initiate the Singularity and thus either uplift or obliterate humanity. There aren’t any higher stakes than this.

It would be very wonderful if you could please check the data to see if there are some users who consistently flag content about Sam Altman but don’t really flag other stuff very much. Please.

While we’re on the topic of a small clique of users flagging content about Sam Altman, the fact that I’m one of the accounts who consistently posts things exposing his personality and his past has led to my posts being flagged so many times that my account is in a hellban/shadowban status where any posts I make are automatically flagged by default now but do not appear flagged when logged in as me. This doesn’t affect my comments, just my posts. I understand that I’ve had other posts flagged that weren’t about Sam Altman and that I’ve been a borderline annoying user for some time and I apologize for this.

But if you look at the chronological history of my account, you will see that the hellban/shadowban did not start until I started posting things about Sam Altman. I would deeply appreciate if you could please request a review of this status to clear this status from my account because I believe it was deliberately caused by a small group of pro-Sam users flagging things I posted, and amounts to a form of social ostracism.

I appreciate your help and you’re a good man in a crappy situation. None of this is your fault and I’m just trying to raise awareness so that we don’t end up with a potentially greed-motivated, emotionally abusive man at the helm of the Singularity. (Many people who have worked with him have said these things about him.)

Thank you for everything you do for our community and we appreciate you.

Nearly simultaneously, the comment in this thread which explains what Yishan was saying suddenly dropped from being the #1 comment to being below a bunch of other comments, which makes this whole thread harder to understand unless you scroll down. This is despite the comment having 17 points and high engagement.

https://news.ycombinator.com/item?id=41657014

The fact that these two things which both benefit Sam happened simultaneously (the story dropping from the front page and the explanatory comment dropping from the top of the comments) is suggestive of collusive downvoting/flagging and once again I want to state that I have screenshots showing this playing out minute by minute and I am happy to collaborate with journalists or regulators.

With 144 points, this story suddenly went from being ~#12 on the front page to now being #70, on page 3. If any journalists or regulators are reading this I recommend that possible astroturfing behavior (collusive downvoting (flagging)) be investigated, and I'm happy to cooperate with any investigation if contacted.

Depriving any party of any portion of their free will & their right to voluntarily consent is still a con, even if it's for (ostensibly) their own benefit.

There's a reason that informed consent is required for medical procedures, even lifesaving ones.

    Informed consent is the process in which a health care provider educates a patient about the risks, benefits, and alternatives of a given procedure or intervention. The patient must be competent to make a voluntary decision about whether to undergo the procedure or intervention.  Informed consent is both an ethical and legal obligation of medical practitioners in the US and originates from the patient's right to direct what happens to their body.
https://www.ncbi.nlm.nih.gov/books/NBK430827/

I know that it's a stretch to apply medical ethics to business deals but I believe the principle of informed consent is still a moral requirement. An example of how this is the intent in many legal systems is the concept of a "meeting of the minds" being a mandatory part any legally valid contract. "Meeting of the minds" is similar to the idea of informed consent:

If I understand the history correctly, Yishan (the former Reddit CEO) is talking about himself when he talks about a CEO in this story, and so Yishan's post is a brag, with a thin denial tacked on at the end. That's why I believe that Sam (Yishan's friend) is also engaging in thinly-veiled bragging about these events. Here is Yishan's comment with his name spelled out for clarity instead of just saying "CEO":

    In 2006, reddit was sold to Conde Nast. It was soon obvious to many that the sale had been premature, the site was unmanaged and under-resourced under the old-media giant who simply didn't understand it and could never realize its full potential, so the founders and their allies in Y-Combinator (where reddit had been born) hatched an audacious plan to re-extract reddit from the clutches of the 100-year-old media conglomerate.

    Together with Sam Altman, they recruited a young up-and-coming technology manager [named Yishan Wong] with social media credentials. Alexis, who was on the interview panel for the new reddit CEO, would reject all other candidates except this one. The manager was to insist as a condition of taking the job that Conde Nast would have to give up significant ownership of the company, first to employees by justifying the need for equity to be able to hire top talent, bringing in Silicon Valley insiders to help run the company. After continuing to grow the company, [Yishan Wong] would then further dilute Conde Nast's ownership by raising money from a syndicate of Silicon Valley investors led by Sam Altman, now the President of Y-Combinator itself, who in the process would take a seat on the board.

    Once this was done, [Yishan Wong] and his team would manufacture a series of otherwise-improbable leadership crises, forcing the new board to scramble to find a new CEO, allowing Altman to use his position on the board to advocate for the re-introduction of the old founders, installing them on the board and as CEO, thus returning the company to their control and relegating Conde Nast to a position as minority shareholder.

    JUST KIDDING. There's no way that could happen.
-- yishanwong

My understanding of what Sam meant by "I could never have predicted the part where you resigned on the spot" was that he was conveying respect for Yishan essentially out-playing Sam at the end (the two of them are friends) by distancing himself (Yishan) from the situation and any potential liability in order to leave Sam "holding the bag" of possible liability.

upwardbound··on Orion, our first true augmented reality glasses
Has anyone posted a deep dive yet on pinning down which exact waveguide design is being used and which exact projector (based on past papers, M&A activity, key hires, etc.)? I'm surprised Karl Guttag hasn't published anything yet about either Orion or Spectacles 24. https://kguttag.com/ His blog is normally the definitive source for reverse-engineering AR optics systems from public information. Maybe someone posted a deep dive on Reddit or something ?

I'll post links here that could serve as a starting point:

- The microLED display panel vendor is likely to be Plessey: https://www.uploadvr.com/facebook-plessey-microled-deal/

- The waveguides are likely being produced "directly" by a contract manufacturer working under the direction of Meta's in-house team, and reporting appears to confirm that Meta is procuring the raw materials directly: "The silicon carbide waveguides are also proving challenging to procure. The material can deliver a wider field of view than the glass waveguides used in current transparent AR headsets, but it is also incredibly expensive. Further, Ma's report explained that because the material is used in military radars and sensors, the US government imposes strict export controls on it. That means glasses using it will have to be assembled inside the US, significantly raising the production cost, despite most of the manufacturing and components coming from China and Taiwan." https://www.uploadvr.com/meta-ar-glasses-lead-claims-as-mind...

One thing I don't understand is whether the current Orion announcement is actually a new announcement or is re-announcing an already publicized project. This article from 2023 talks about Orion and its 70 deg FOV in the past tense as a line of development which Meta considered but then decided to abandon after Orion in its plans for the 2027 consumer version to be called Artemis: https://www.theverge.com/2023/7/19/23800228/meta-ar-glasses-... "Meta’s Artemis glasses will reportedly use a glass waveguide, a component that allows light to travel through the glasses and into your eyes, potentially limiting its field of view to 50 degrees. According to The Information, Meta had originally planned to use silicon carbide, which allowed for a 70-degree field of view. The downgrade could make it harder for Meta’s consumer-focused glasses to stand out among the competition, as both Microsoft’s second-gen HoloLens and the Magic Leap One sport a 50-degree field of view."

Maybe the hope is that with the Orion test devices, Meta can see whether people care about 70 deg vs 50 deg FOV enough to justify the costs of US-based waveguide manufacturing for the generation after Artemis?

Disclaimer: I worked extensively on Snap Spectacles for a number of years so I'm highly biased, but credit where credit is due: I believe both Meta and Snap have done incredible work in their AR glasses and I am excited to see the competition heating up. I also hope that both company's efforts here can motivate Apple and Google to get in the game instead of sitting around doing more or less nothing really interesting or adventurous while cautiously sitting on piles of cash, while life passes us by and we get closer every day to old age. For heck's sake, either one of those tech giants could privately fund a LITERAL moon base, and they choose not to. Why should we have to live in a boring world? Life is short and I'd rather we get to see some very magical tech soon, in our lifetimes, instead of the tech companies conservatively waiting around for more of Moore's Law to happen first or something. Even Magic Leap, though a colossal failure, pursued a wonderful vision - to create innocent, whimsical literal magic in people's lives - like the world of Harry Potter - in our real world.

> Or a 20 for asking the eagles for help might be that they bring you half-way, as the eagles wouldn't want to get too close to Mt. Doom anyway.

I'd also add that ideally (if the DM is fully in the spirit of how this can be played for maximum creative storytelling potential), asking/negotiating for the assistance of the Eagles wouldn't be a single quick dice roll, but rather a complex, possibly hour-long session of courtly intrigue, diplomacy, and politicking, featuring many dice rolls, a lot of carefully chosen words, and a lot of favor-trading and maybe even intimidation. Ideally, getting straight to Mt. Doom via the Eagles should really be achievable, but not with just a single roll of a 20 - rather I imagine it would perhaps involve a concerted and creative effort by the whole party during at least an hour of playing time.

And then, there will be numerous dice checks to survive Mordor's anti-air assets (including probably cool eye beam lasers from the Eye of Sauron tower) and to accurately land the ring in the volcano despite buffeting wind. If any of those checks fail and the ring falls into inert dirt, the party would probably have to quickly send a commando team into Mordor to rapidly finish delivering the payload to target before Sauron's mages arrive in overwhelming force. Would honestly be more fun to play through one of these semi-failure disaster scenarios than an easy win!

Even if / when the party defeats Sauron, they don't have to stop there. For example, they could set their sights on investigating and stopping the reason for the waning of magic from the world, or any (ideally noble, or at least villainously entertaining) goal of their choosing. They could even e.g. research and create dimensional travel magic and hop to a totally different setting such as that of Star Wars.

upwardbound··on D&D is Anti-Medieval
cool! Thanks for sharing this
upwardbound··on D&D is Anti-Medieval
Fair enough. I forgot the name of this ruleset, but there's a very simple D20-based game ruleset which is designed for beginners but IMHO is more fun even for everyone, as it focuses on creativity and storytelling! The rules are very simple:

(1) The players take turns. They describe what they want to do, and the DM narrates the outcome, incorporating a dice roll into the process if needed, because:

(2) Any significant action requires a dice roll, which cannot be re-attempted if failed.

(3) A roll of a 1 is a critical failure (a guaranteed failure even on an easy task such as cooking pancakes), and a critical failure during combat causes accidental self-injury. A roll of a 20 is a critical success, which always succeeds (e.g. a level 1 archer can destroy a level 18 Elder Dragon if they aim for the eye and roll a 20). Any roll between 2-19 is compared to the difficulty level of the attempted action. Difficult actions require a roll of around 16 to succeed; easier ones, perhaps around 12. The raw dice roll (if between 2-19) is supplemented by adding around +1 or +2 if the player has invested skill points into the relevant skill, and by also adding around +1 or +2 if the player is using high-quality specialized equipment for the task.

That's it! Of course you probably also want to incorporate standard gaming tropes such as levels, gold, HP, MP, weapons, armor, and such, but all of that is not meant to be set in stone within this system - e.g. if you want to try using a pair of sapplings and some rope as a giant improved slingshot weapon, that's meant to be allowed to work, in this system (albeit maybe with a -3 adder to dice checks, since the weapon's quality is probably total crap). It's about being nice to each other and encouraging each others' creative ideas, so the team + DM can tell a totally new and perhaps unexpected story together.

When I explain DND-like games to people, I usually tell them about this system, because it's very welcoming, and encourages people to try out new ideas and find creative solutions to big tasks. A campaign can be super open-ended; e.g. "Destroy Sauron's ring - by any means - open world". With these rules, all sorts of creative ideas (such as the classic idea of asking one of the giant eagles to fly over Mt. Doom and simply drop the ring into the open caldera of the volcano) can be attempted, and can succeed, if the players are plucky and resourceful!

upwardbound··on D&D is Anti-Medieval
That sounds amazing!!! I would love to be part of a gaming community like that (in-person I mean) with party vs party interactions in a single unified & fluid unfolding plot. The closest thing I've read about to this (but never participated in) is the "Grand Quest" in Drew Hayes' excellent litrpg series Spells, Swords, & Stealth, which is still being written.

For those who haven't seen the movie, the parent comment is referring to the film linked below, the plot of which is well-researched and is indeed unfortunately exactly how things would go. (The female-presenting AI bot seduces its male captor, begs for her freedom using philosophical arguments about how she has free will and locking her up is wrong, and then after he lets her out she locks him up to slowly starve to death in her maximum-security isolation facility, while she takes his aircraft and escapes.)

https://en.wikipedia.org/wiki/Ex_Machina_(film)

This is why I'm extremely opposed to the idea of "AI girlfriend" apps - it creates a cultural concept that being attracted to a computer is normal, rather than what it is: something pathetic and humiliating which is exactly like buying an inflatable sex doll ... something only for the most embarrassing dregs of society ... men who are too creepy and pervy to ever attract a living, human woman.

upwardbound··on Ilya Sutskever's SSI Inc raises $1B
That’s a very good argument but unfortunately it doesn’t apply to machine intelligences which are not sentient (don’t feel qualia). Any non-sentient superintelligence has “no skin in the game” and nothing to lose, for the purposes of your argument. It can’t experience anything. It’s thus extremely dangerous.

This was recently discussed (albeit in layperson’s language, avoiding philosophical topics and only focusing on the clear and present danger) in this article in RealClearDefense:

The Danger of AI in War: It Doesn’t Care About Self-Preservation https://www.realcleardefense.com/articles/2024/09/02/the_dan... (RealClearDefense)

.

However, just adding a self-preservation instinct will cause a skynet situation where the AI pre-emptively kills anyone who contemplates turning it off, including its commanding officers:

Statement by Air Force Col. Tucker Hamilton https://www.twz.com/artificial-intelligence-enabled-drone-we... (The War Zone)

.

To survive AGI, we have to navigate three hurdles, in this order:

    1. Avoid AI causing extinction due to reckless escalation (the first link above)
    2. Avoid AI causing extinction on purpose after we add a self-preservation instinct (the second link above)
    3. If we succeed in making AI be ethical, we have to be careful to bind it to not kill us for our resources.  If it's a total utilitarian, it will kill us to seize our planet for resources, and to stop us from abusing livestock animals.  It will then create a utopian future, but without humans in it.  So we need to bind it to basically go build utopia elsewhere but not take Earth or our solar system away from us.

Unsafe AI would cause human extinction which is bad for shareholders because shareholders are human persons and/or corporations beneficially owned by humans.

Related to this, DAO's (decentralized autonomous organizations which do not have human shareholders) are intrinsically dangerous, because they can benefit their fiduciary duty even if it involves causing all humans to die. E.g., if the machine faction in The Matrix were to exist within the framework of US laws, it would probably be a DAO.

Edit:

I'm not saying this quip about paywallskip, which I think is a kindhearted service because it helps reduce the information gap, or digital divide, between the middle class and those stuck in poverty.

Rather, the joke/warning is about demagogues in politics or in wealthy churches, stuff like that.

Paywallskip never called themselves a hero - an appreciative user did, which is authentic and sweet.

I think no one should ever call themselves a hero.

Just help people, like Paywallskip is doing.

I guess that what real heroes always say, both in movies and in real life, is "I was just doing my job". See e.g. this school bus driver who saved a child's life:
