<p>An AI with this “universal morals” could mean an authoritarian regime which kills all dissidents, and strict eugenics. Kill off anyone with a genetic disease. Death sentence for shoplifting. Stop all work on art or games or entertainment. This isn’t really a universal moral.</p>

<p>I gave their example “correct” prompt (“Flat, circular, non-itchy, non-painful red rash with a ring, diffuse throughout trunk. Follows week of chills and intense night sweats, plus fatigue and general malaise”) to both ChatGPT and Gemini. And both said Lyme disease as their #1 diagnosis. So maybe it is okay to diagnose yourself with LLMs, just do it correctly!</p>

<p>Interesting puzzle. 32385 is 255 pick 2. My guess would be, to hopefully make interpretation easier, they always had the larger number on one side. So (1,2) but not (2,1). And also 0 wasn’t included.  So perhaps their generation loop looks like [[(i,j) for j (i-1 -> 1) for i (256 -> 1)]</p>

<p>We wouldn’t have a long back and forth to establish a common language, we would likely send something like <a href="https://cosmicos.github.io" rel="nofollow">https://cosmicos.github.io</a>.<p>“CosmicOS is a way to create messages suitable for communication across large gulfs of time and space. It is inspired by Hans Freudenthal's language, Lincos, and Carl Sagan's book, Contact. CosmicOS, at its core, is a programming language, capable of expressing simulations. Simulations are a way to talk, by anology, about the real thing they model.<p>CosmicOS is structured to communicate the usual math and logic basics, then use that to show how to run programs, then send interesting programs that demonstrate behaviors and interactions, and start communicating ideas through ”theater” and simulations. This is inspired by Freudenthal's idea of staging conversations between his imaginary characters Ha and Hb.”</p>

<p>Your home internet and your cellular provider can “attest” you make a monthly payment - right now, the scarcity of ipv4 and cell phone numbers often serve this purpose. A government agency or bank can attest you’re a real person. A hardware manufacturer can attest you purchased a device. A PGP style web-of-trust can show other people, who also own scarce resources and they may trust indirectly, also think you’re real.<p>Blockchain may be largely over-hyped, but from this bubble I think important research in zero-knowledge proofs and trust-less systems will one day lead to a solution to this that is private and decentralized, rather than fully trackable and run by mega-corps.</p>

<p>It’s pretty easy to guess what features (either manually made or AI based) the phishing detector saw:<p>1. “Facebook” and “login” in the URL<p>2. URL redirect<p>3. “Facebook login”, “password login, “forget password” etc in text body<p>4. The quoted email from Spotify sounding close (in vector space) to phishing text.<p>5. A link to Facebook settings, followed by a series of steps; these instructions say to log in to a non-Facebook url using your Facebook email<p>All of these together was probably enough to hit some threshold. 
From there the issue was just misaligned personal incentives, all along the chain from engineers at Facebook to Netcraft and Digital Ocean, that leads to false positives being an acceptable outcome.</p>
