Fascinating to see Anthropic and SpaceX offering free equity positions to the public. Had that ever happened in the history of the stock market? (For real, successful, growing firms?) One challenge will be stock buy backs. Currently firms do that to optimize taxes. But if you’re low income you want that stock throwing off cash, not just growing in value while you watch it. Interesting way to help the public benefit from these companies while cutting out the horribly run middle man (Federal government!)
it'd be interesting if si produced some sort of an economy where private corporations become the primary financiers of social welfare (aka universal high income) rather than governments. i know indirectly this is what happens through taxes but imagine it working directly in some fashion (likely through ownership, growth, & some form of liquidity). the reason why is because it's pretty clear now that si will create super power law outcomes for almost all of society. & more specifically current mechanics for income redistribution like income taxes will become way less effective over time too since the income gaps will continue to increase drastically (see sf & its housing market as an early example of this). basically some form universal equity ownership as an intermediate step before full automation occurs. fun to think about all of the implications of this.

Love this stuff. Debated doing a company in this space instead of SportsVisio but wasn’t convinced that the big publishers cared enough to invest (or the TAM being big enough). But super fun problem, cutting edge tech and domain.
This is why the anti-cheat arms race is getting so interesting. Riot is pushing Vanguard further into hardware-backed trust, attestation, VBS/HVCI, IOMMU and deeper platform security. At the same time, AI-assisted reverse engineering is making it much faster to tear apart the software sitting on top of those protections. @k0mkc is showing heavily devirtualized VGK internals and says he can now devirtualize the entire thing. On the EAC side, @in19h has published tooling that recovers large parts of a heavily virtualized Easy Anti-Cheat Linux sample into readable code and IDA artifacts: github.com/19h/eac-linux-dev… There is an important parallel here with EDR. An EDR is only as effective as the detection engineering, threat hunting and R&D behind it. Anti-cheat works the same way. You need researchers constantly following new techniques, detection engineers turning that research into useful telemetry and detections, and people actively hunting for behaviour that existing rules may miss. That means continuously keeping up with: - new cheat architectures - kernel abuse - BYOVD - hypervisors - DMA - firmware tricks - input manipulation - virtualization + obfuscation - new bypass techniques The game was already there. AI is speeding it up and lowering the barrier to reversing, classification, devirtualization and research. That forces both sides to iterate faster. A lot of respect to the Vanguard team as well. They have clearly been keeping up with some of the most cutting-edge work in Windows security, hardware-backed trust, kernel security and anti-cheat research, and their recent Vanguard On-Demand changes show how quickly the defensive side is evolving too. This is becoming a much faster research cycle on both sides. Where does the arms race go next? Huge credit to @k0mkc and @in19h for the research. #AntiCheat #ReverseEngineering #WindowsInternals

Ben Horowitz says Anthropic is one of the most negligent companies he’s ever seen on security "The irony on these things is wild. Anthropic is one of the most negligent companies that we've ever seen in terms of their own security." "They let Claude code, one of their crown jewels, just like walk out the door because they had such bad OPSEC." "I'll tell you a funny story. So when we first got Opus 4.5, we were doing cybersecurity checks for the firm. So we had an agent basically set up a website for a pet store. And then we took another agent and said, 'Tell us if we can exploit that web store.' And it gave us all the exploits it could find. So Opus 4.5 wrote really buggy code. Great." "And then we said, 'Oh, the SQL injection you found, is that actually exploitable?' And it goes, 'Let's pop it open.' And the agent using Opus 4.5 breaks into the website and steals all the [data], and we call Anthropic. And what they tell us is, 'You prompted it wrong.' That was their answer." "So these guys are doing that on the one hand. And then on the other hand, they're coming up with theoretical scenarios about other people's software. That's bad. And so like, what the hell." "On the distillation thing, you know, to build their model, they distilled the works of every author, every creative, every scientist for the last 2000 years. For them to be complaining about distillation, which, by the way, distilling a model is not even illegal. It's just a violation of the terms of service." "It's just so much. And the fact that they get people to write things supporting these bananas, ridiculous, two-faced ideas. And the timing here is very suspicious."

Not gonna lie but this is a freakin’ cool demo. Probably meaningless because this isn’t street legal or even available to buy. But it is cool which counts for something. Nice to keep seeing stuff built that makes you feel like we actually are finally living in the future we envisioned as kids. Walking around SF I captured this row of self driving Waymo’s in a line. It’s arriving!

Honestly I think this is why most startups run circles around big companies. Not because the big companies lack resources (smart people, plenty of money, distribution). But because they have so many committees and can't get out of their own way. We just landed a large customer (solid 9 digit annual revenue) and it's shocking the amount of meetings to have meetings with 5-10 people in each to make a decision. Roll out plans are in months/quarters, not days or weeks like we would normally move on. Our (and every other small firm's) biggest challenge as we grow is figuring out how to stay lean as a company and make decisions quickly (like SpaceX, which is not a small company these days).
A retired NASA engineer who had worked on the Space Shuttle program for 25 years was hired by SpaceX at age 62. He described the first week as the most disorienting experience of his professional life. At NASA, a design change required 3 meetings, 2 committees, a review board, and 6 to 18 months of documentation. At SpaceX, his new supervisor said "if it works, build it. If it doesn't, change it by Friday." He sat at his desk after the first day and called his wife. He told her he felt like a man who had been swimming with ankle weights for 25 years and someone just cut them off. He could move. He could decide. He could build something in the morning and test it in the afternoon. The constraint that he had accepted as the nature of aerospace engineering turned out to be the nature of bureaucracy. Within 6 months he had contributed to more design iterations than he had completed in his last 5 years at NASA. Not because he was working harder. Because the time between having an idea and testing the idea collapsed from months to hours. The same brain. The same knowledge. A different operating system. He described a specific moment where he proposed a modification to a Raptor engine component. At NASA, the proposal would have entered a queue. At SpaceX, the modification was machined by the end of the day and tested by the following morning. He watched his idea become a physical object in 18 hours. At NASA, 18 hours would not have been enough to schedule the first meeting to discuss whether to schedule a meeting. He told an interviewer: "I didn't get smarter when I went to SpaceX. I got faster. The intelligence was always there. The system was in the way." The difference between SpaceX and NASA is not talent. NASA has extraordinary talent. The difference is the time between a thought and a test. SpaceX compresses it. NASA elongates it. The same engineer produces 10x more at SpaceX than at NASA because the bottleneck was never the engineer. It was the meetings about the meetings about the work.

Love this story. Honestly stuff like this is why we built @SportsVisioAI You shouldn’t need to stay up late hand doing charts. You shouldn’t need a dedicated staffer pouring over data to understand what happened. (Computers are good at that!) It’s about removing the manual labor parts and democratizing access to the cool insights. (And giving kids all their clips too!)
My son tried out for his high school basketball team three years in a row and got cut every time. He's a good kid, but he's five foot six and not very fast, and the third time it broke his heart. He'd practiced every single day that summer. He came home from the final cut list and went straight to his room. The next morning, the coach called our house and asked to talk to him. He said he had a problem.

Gary doesn’t mention year two. Even if you got the loan for 50% of your shares (which you now don’t own), by year two you’d have to borrow another gigantic amount. You’re now worth more dead than alive!
The academics think the founder who raised at $2B valuation can pay but they can’t You are a founder who owns 50% of your company and you have 20x voting rights. You owe 5% on $10B in the asset seizure tax. You owe $500M of your paper $1B. Find me a way to get a loan for half your illiquid net worth. You cant. The asset seizure proponents are dishonest and also it’s not a 5% tax on startups. It’s a 50% tax in this simple case.

Loved this story. One of my favorite Twitter memories was way back (when that’s what it was called) I met a CyberCommand very senior officer in his classified offices for the first time. He said I was “part of the cyber glitterati” (I wasn’t even sure what that meant, but found out it was good!) and he’d been following me from a secret account. Made the rest of the meeting very easy. You never know who’s following your journey and what you post and share. Keep doing good work and building public and being kind and you’ll be surprised at the dividends down the road.
i recently met a wildly successful founder who had exited for an enormous amount of money & whom i admired cuz he’d dm’ed me saying he loved my writing. i never knew cuz he’d never liked, replied to, or interacted with a single post of mine. i had absolutely no idea he was even reading, & strangely never even followed. just goes to show you the feedback loops on x are incredibly lossy. you have no idea who’s consuming your thoughts, who you’re impacting, or who absolutely despises everything you say. your visible audience & your actual audience are two very very different things.

Lots of drama around Valar Atomics and Day One Ventures. Given all this bad stuff (which was known back in 2022 apparently) I am surprised they took funding from them at all.
turns out that Masha Bucher, founder of Day One Ventures. Also known for .. - being a member of the Kremlin Youth - a PR manager for Jeffery Epstein - starting a VC fund whose first investor is a (now sanctioned) Russian Bank's founder - a FBI report where a confidential source reported "Day One Ventures was in Silicon Valley to steal technology.” is not the best VC to work with.

Tao is completely missing the mark - what he's describing is actually completely standard for drug discovery. There are tons of drugs that have saved millions of lives without any person on Earth understanding fully the mechanisms of action that enabled them to do this.
This is a slide from Terence Tao's 'Math 2.0' public lecture yesterday evening at Caltech. I am highly confident that, if the cure actually worked, almost any Stage 4 cancer patient would tell you that human comprehension of its mechanism is completely irrelevant to them.

Love this idea. I suspect this is something we’ll see more in the future. Building games to illustrate a specific concept. It’s a clever way to leverage AI to quickly put something together that’s engaging and educational at the same time. Could do many topics (cooking, VC, Palestine, marriage, whatever)
ever wondered why you can't find housing in sf? i made a game where you try to build some. every site is a real project and every law is real. see how far you get.

Crazy times we are in now. Non hackers can just use AI to decompile binaries or just feature reconstruction them and then port to whatever they want and add whatever they want. In days. Without anyone else assisting. 🤯 kevin.md/i-put-melee-in-my-l…

I didn’t watch the clip because I don’t think there’s a giant secret sauce. I think there are a few simple things: 1) Learn offense before trying to secure things 2) Don’t stay in the military or intelligence community forever, do 1-5 years and then leave 3) Live in a place that rewards risk taking and innovation and has strong STEM education and access to capital. That’s it. The US has some great success stories (with similar paths) but usually they (and others) are limited by one of those three.
Israel’s elite military tech units have produced many of the world’s largest cybersecurity companies. Unit 8200 alumni have gone on to start Wiz, Check Point, Palo Alto Networks, CyberArk, Imperva, and many more. And 3% of graduates from the elite Talpiot program have founded unicorns. @wiz_io co-founder Yinon Costica explains why these programs have become such powerful talent ecosystems, and what you actually learn during those years.

Interesting post from my friend Andrew. The comments are overwhelmingly they’d rather be captain of a losing team. A couple point out context matters (I agree) Personally I’d generally opt for being a member of the winning team. I often find myself in leadership roles… which is partially because I’ve got lots of opinions and talk a lot and I’m strong willed and don’t mind leading. But more than those I’m super competitive and absolutely hate losing. I’d rather be a role player (by far!) than the star if it meant winning. I play on a really good basketball team and I’m usually one of the worst on the squad… but we win. A lot. I love great teamwork and learning from other high performers. There are times where being the captain of a losing squad makes sense (first time in leadership, turning the ship around, you are protecting someone junior, etc.) But generally if you’re success oriented and it’s about the team and not your ego I think the winning team is the play over captain.
Interesting Goldman Sachs interview question. Your answer reveals more about you than you think.

15 years ago it was much more acceptable. But today given everyone uses Luma (or is forced to use Partiful) which carefully tracks responses there’s no excuse for having way more people than you have space for. Last year I traveled an hour to get to an event during NYTechWeek and arrived 15 minutes after it started and was turned away because of numbers. I was pissed, it’s super disrespectful to your attendees. It implies their time means nothing. I get it that showing up 2 hours after doors open to a place with a long waitlist you might not get in. But you also need to manage the guest list and demonstrate some respect for the guests.
I’m sorry, it’s not a “successful” startup event if most of your guests are waiting in a line the whole time. Props to everyone that got 1000+ sign ups for their SF Tech Week event, but newsflash, these events actively hurt your brand and are not building “community” as your job title suggests. When I see people posting videos of their long lines at their event, it’s not the flex you think it is. People won’t come to your events in the future since you don’t know how to craft a quality guest experience. Your “sorry demand was incredibly high and despite our best efforts we couldn’t accommodate everyone” afterwards doesn’t excuse it 😬 As someone that’s hosted 100+ of my own startup events, I'm the first to know how much work goes into organizing one, and I applaud everyone putting that work in promoting it. But I can confidently say that any good host can estimate churn better and take more active steps to send out reminders and receive attendance confirmation (e.g. requiring a secondary confirmation is sooo easy and can greatly increase your attendance estimates / cut churn in half). Sending a basic partiful reminder is not doing your job 😂 If you're hosting this week, here’s an idea. Try to send your own confirmations by text and force your guests to reply to attend so you can also have an “actively confirmed” headcount. That's literally how I use @markit_ai__ There are still tons of awesome events this SF tech week and stellar hosts doing a great job, it’s just a shame some organizers are chasing clout/vanity and hate to see peoples time wasted who traveled a long way to be here

See, this is what we want robots for. Clean waterways, sweep streets, etc.
A robot is cleaning rivers completely autonomously. 🌊 Meet Hebao H3, an autonomous surface-cleaning boat developed by Dongfang Water. Using onboard AI vision and GPS, it can detect and collect floating waste such as plastic bags, bottles and leaves while avoiding obstacles. When its collection bin is full, the H3 can automatically return to its base. Would you trust robots to keep our rivers clean? 👀 ⚠️ This content is shared for informational purposes only.
