    I am crossing the Rubicon and backing the Republican Party and President Trump. Many — including a former version of myself — get trapped in a mental framework that becomes their identity and prevents them from radically evolving their thinking with new facts and information. I

    It’s hard for me to openly criticize a company I used to love and gave so much to. But @PayPal’s new AUP goes against everything I believe in. A private company now gets to decide to take your money if you say something they disagree with. Insanity. paypalobjects.com/marketing/ua/p…

    Realizing that this was and continues to be a lie was a turning point for me. Regardless of where you stand on this election, you should watch the video below and compare it with the spin pushed by the campaign just to know you’re being manipulated.

    How Libra Was Killed. I never shared this publicly before, but since @pmarca opened the floodgates on @joerogan’s pod, it feels appropriate to shed more light on this. As a reminder, Libra (then Diem) was an advanced, high-performance, payments-centric blockchain paired with a

    Went to UCLA this afternoon to talk to people peacefully. Few interesting takeaways: 1) Most of them openly say they support Hamas, a designated terrorist organization; 2) They say 10/7 atrocities, rapes, murders, didn’t happen. The official line is “even the NYT debunked it!”;

    This timeline is so off. Can you imagine a prominent Congress representative from another time celebrating someone who openly supported Osama Bin Laden, ISIS… and organized anti-West / American uprising? Wild.

    This is so wild. Let me get this straight, the EU is trying to censor an interview with a US Presidential candidate on a US platform? Insane.

    Worth pointing out that when we announced a mere whitepaper for Libra on 6/18/19, it took less than 24h for me to be called to testify in front of both the Senate and the House. Meanwhile the total meltdown of FTX unscrupulously misappropriating ≈$10B of customers funds…

    I watched that SBF @andrewrsorkin interview, and I have to say that I still can't believe what I just witnessed. I'm actually speechless at the level of reality distortion field at play here. Also... audience applauding at the end? WTF!

    It’s exhausting. Exhausting to see the hate against Jews rise from every corner of the world, and from people who have no connection to the Middle East whatsoever. These very people who have never felt outrage for real atrocities taking place all around the world. No Jews, no
