For Hwang, his time with Obama wasn’t just a job — it was a crash course in why healthcare is so hard to fix. Watching policymakers wrestle with the Affordable Care Act as a young staffer showed him just how deeply the system’s dysfunction runs, long before he ever thought about building a company inside it. That early exposure, combined with what he witnessed during COVID, is what ultimately convinced him that the problem was worth a lifetime of work.

Why Google & Apple Maps don't workPicking the right exit when you are road-tripping is not a solved problem. The "Add Stop" functionality on Apple is frustrating, often-times wrong, and has no option for rest areas. I've noticed the "Add Stop" options are not holistic - they are just a smattering of options at exits ahead. Google Maps and Apple Maps on the phone are great when you are doing a radial search, but you don't care about the options that are near "as the crow flies" but far in terms of detour time. You want "1 minute off the exit for the next 5 exits" options.
众所周知，海湾地区是“文明世界的十字路口”，自古以来连通着欧亚非三大洲。然而，它距离全球最重要的需求发源地，都有一定的距离：与西欧差了几千公里，与东亚差的更远，与美国更是差太远了。对于那些追求低延迟的任务来说，海湾地区其实不太合适：理想状态下，从阿联酋到伦敦的来回通信延迟(RTT)约为120ms, 到香港超过150毫秒，到东京更是可达200毫秒。能不能接受这样的延迟，取决于任务性质，一般的AI推理还是可以的。至于AI训练，就更可以了，因为训练对通信延迟的敏感性极低，而且完全可以本地训练。
