1/ We discovered something totally unexpected about the neural structure of consciousness that overturns decades of thinking on its biological basis and brings us significantly closer to the recipe for generating conscious awareness. New preprint: biorxiv.org/content/10.64898… (led by @HesseJanis, with @FrankLanfranchi, @_conor_mcgrory, @Yuelin_Shi, and @EngelTatiana)

I'm starting to think mathematics were not beautiful because it "describes the beauty of nature" but rather because human mathematicians only went after beautiful but suboptimal descriptions lol
You can do Fourier transforms in O(N log(N)^0.9999999999999) time. Fuck this gay chud universe

Healthcare staff spend millions of hours each year calling insurance companies and navigating portals. @SplendorHealth automates insurance workflows (benefits verification, prior auth monitoring, credentialing) for healthcare companies, eliminating the headaches of portal access, EDI, and AI phone calls. ycombinator.com/launches/Ocr… Congrats on the launch, @tiwaaina!

Grateful to be featured in @Forbes and to go deeper and share the vision behind @phosphorcap. Thank you to @dasha_shunina for taking the time to understand Phosphor’s mission.
That's what @garrytan, President & CEO of @ycombinator, said about him: “His perspectives are exactly what our founders need”. Meet @kul, twice-exited YC founder who just launched a new fund investing exclusively in YC startups. forbes.com/sites/dariashunin…

Why should we celebrate Juneteenth? For the same reason we celebrate the Fourth of July. For our country has two foundings. The first, a promise of "a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal."

Excited to share that I've joined @FirstRound to invest in exceptional founders at the earliest stages of their journeys. 🚀 First Round backed some of my close friends last year (special thanks to @aditabrm for the introduction and @the_yuppy for the support), and it's been a joy to see the deep commitment and service they provide to their founders. Even though I'm only one day in, the intensity and care with which the team operates has been inspiring. I'm looking forward to working closely with and learning from @btrenchard, @brettberson, and the rest of the First Round team. It's a real privilege to be a part of such a storied firm, and it's an honor to work alongside visionaries at the most formative stages of company building who are fundamentally changing how we work and live. This new chapter builds upon almost two years at @NEA, where I had the opportunity to work with so many kind, humble, and high integrity people. I'm grateful to the NEA team for taking a bet on me and giving me the opportunity to learn the craft of venture and support some remarkable companies. To the founders I've worked with and those I've yet to meet - thank you for letting me be a part of your journey. 🙏

🚨 The Yemen groupchat fiasco is just the beginning. The next wave of national security leaks will be worse. Our digital infrastructure is not built for a world where: 1️⃣ Groupchats run everything. 2️⃣ AI reads, creates, and weaponizes their contents. It’s collapsing. That’s why we built Kibu. 🧵

Fascinating that Andrew Carnegie wrote this early retirement memo to himself aged 33 ("I will resign business at thirty-five") and then proceeded to ignore it and spend the next three decades brutally dominating the steel industry instead
