UL NO. 403: Signal Investigates Rumored Zero-Day Bug, AI Predicts New COVID-19 Strains, Dwindling US-China Scientific Collaboration...

In this edition we look into Signal's investigation into a rumored zero-day bug, how Harvard and Oxford researchers are using AI to predict new COVID-19 strains, the dwindling collaboration between American and Chinese scientists, and the European Commission's CSAM detection bypass

Unsupervised Learning is a Security, AI, and Meaning-focused podcast that looks at how best to thrive as humans in a post-AI world. It combines original ideas, analysis, and mental models to bring not just the news, but why it matters and how to respond.

Hey there,

Super excited about this X thread I just created about the ExtWis extraction of the convo between Neri Oxman and Lex Fridman. X broke the thread so you have to read upwards instead of down, but it’s worth the scroll!

I also woke up with a new joke in my head on Sunday:

“GenZ people should call perpetual liars ‘being stuck on CAPS LOCK’, because everything they say is CAP.”

I hope you have a stellar week! Let’s get into it.

Signal's been chasing rumors about a supposed zero-day bug linked to their 'Generate Link Previews' feature. The rumors have been spreading quickly, with claims that the bug could allow a full takeover of devices. But after digging into it, Signal says they've found no evidence that this bug is real. I’d find a vuln like this in Signal especially annoying since I have to update the client like 13 times a week. MORE

US intelligence evidently had concerns that something was being planned in the Gaza strip.

Harvard and Oxford researchers are using AI to predict new COVID-19 strains before they even happen.

Marc’s New Tech Manifesto
Marc Andreessen just put out his latest essay, which he is calling a manifesto. It’s basically an argument that tech is good and that we should be optimists about it. I’m already an optimist and I already agree, but I like how he lays it out. I just wish he addressed the counter-arguments with a bit more zeal. He’s an investor and startup guy. Of course he wants optimism. I’d believe him more if he gave me good steelman arguments on the other side. MORE |

The Best Schools Are On Military Bases
The Pentagon is running the top-performing schools in the U.S., outshining all other American districts in reading and math. These Defense Department-run schools, teaching 66,000 students across U.S. domestic and foreign military bases, saw 55% of their eighth graders proficient in reading and 41% in math in 2022, significantly higher than the national averages of 29% and 26% respectively. I can’t believe 55/41 are numbers to brag about, and 29/26 is just disturbing. For parents/cultures that priortize self-discipline and education (see Asian/Indian/Jewish households), those are probably like 5th grade numbers. The difference in metrics and outcomes across parental/cultural groups needs to be studied and talked about a whole lot more than it is. It’s a set of behaviors, not magic. We all need to start copying what we know works for the successful groups. MORE

Kids Are Spending 5 Hours a Day on Social Media?
U.S. teenagers are spending an average of 4.8 hours per day on social media, with girls spending nearly an hour more than boys. The data, gathered from a Gallup survey of over 1,500 adolescents, reveals that 51% of teens spend at least four hours daily on platforms like YouTube, TikTok, Instagram, and Facebook. The study also found that teens with lower conscientiousness and those with parents who don't restrict screen time tend to spend more time on social media. Stunning. Well, the number is really stunning, but it’s not surprising that those with lower self-discipline and parents who don’t enforce rules spend more time online. I’m starting to think self-discipline is like the thing to focus on for predicting success, and the main thing to try to nurture in kids. This is also supported by the fact that high conscientiousness (one of the OCEAN traits), is the strongest predictor of future success other than IQ. MORE

Where are the Women on Github and AI YouTube?
Why are so few women creating projects on Github? A recent study found that women make up only 6% of contributors on GitHub, and that if you looked at people with more than 10 commits it went down to like 4%. Meanwhile, women are something like 51% of the creators on YouTube. It’s obviously not a creative talent difference, so why aren’t they creating code projects? I especially noticed this recently with AI stuff. I noticed the other day that I follow like a million AI influencer types who are writing code, sharing it, and talking about it on YouTube. And I have only seen a couple that are women. What’s going on, both for AI coding and Github creation in general? Whose fault is this? Is it simply a preference difference? Like is coding for fun just not as interesting to women? And if so, how much of that is something to be addressed or “fixed” vs. being ok? My problem with it being considered a sign of gatekeeping is that there’s no gate on Github. You just post stuff. Most people who do get no love whatsoever but they still post because they want to. And there’s obviously no gate for women creating and crushing on YouTube. Conversely, my problem with it just being “ok” becasue “it’s preference thing” will empower people saying disparities in technical roles in companies is also ok, because “fewer women just want to do those jobs”. I believe that mentality raises biases in hiring managers and DOES create a gate, locking out women who actually want those jobs. What do you think? MORE

Triple Screens? Seriously?

Triple-dividing Your Attention, to Keep Your Attention
There’s a thing that’s been happening on TikTok for a few months now that started with two screens, but now it’s branched into three. They have the main content playing, but in order to retain you they also play something else like a video game with action. So what happens is when you get even micro-bored your brain goes to the video game. Then when they say or do something interesing, you jump back to the main content. Well now they’re triple-splitting the screen. How is a book supposed to compete with that?

Sapolsky is working on what I consider to be some of the most important questions at the intersection of biology and human behavior. Highly recommended. MORE | MORE
