WORLDWIDE CRACKDOWN ON VPNs BEGINS 🇪🇺 EU Executive Vice President Henna Virkkunen is pushing limits on VPN use, warning new age and ID systems must not be bypassed. Utah becomes the first 🇺🇸 US state to target VPNs under age verification laws starting May 6, 2026. Websites can be held liable even if users mask location, forcing a choice: block VPNs entirely or require ID checks from everyone. The Electronic Frontier Foundation calls it a “liability trap” that could push global platforms toward mass identity verification. Momentum is building globally. 🇬🇧 UK and 🇫🇷 French officials are now signaling VPN restrictions may be next. EU-wide age verification is set to roll out across all 27 member states by the end of 2026. x.com/f_philippot/st…


Jane Street made ~$40B in 2025 with 3,500 employees, a ~2x from the year before. At ~65-70% profit margin, that's $8M profit / employee, the highest for a 1000+ ppl company. High-frequency trading continues to be the most efficient money making engine. I want to share an old story about my Jane Street interview in 2014. Jane Street was known for hiring a lot of math, physics and CS olympiad winners from top universities and putting them through many rounds - including, for trading roles, a gauntlet of mental math. It was my 6th interview and my final round and I recall being asked "What is the next day after today in DD/MM/YYYY where all the digits are unique?" They'd toy with you and say "You can use a pencil and paper, if you want" but you knew that was an instant no. Painstakingly and as quickly as I could, I came to an answer. "How confident are you that this is correct on a 0-1 probability scale?" the interviewer said. "0.95", I blurted out, not fully knowing how to answer that. "Are you sure?" After thinking harder for a few more seconds, I realized I could've flipped the digits around to get a closer date. I gave the interviewer my answer. It was correct. "0.95 huh?" he chuckled. That's when I knew I failed. Note: fwiw, other companies that come close in efficiency are - Tether ($90M+ profit/emp) - Hyperliquid ($80M+ profit/emp) and on revenue: - Valve ($50M/emp) - OnlyFans ($37M/emp) - Craigslist ($14M/emp) - Anthropic ($12M/emp, run rate) - OpenAI ($8M/emp, run rate) For comparison, Nvidia is very efficient at scale and is $4.4M/emp.
