On Chinese labs like Moonshot AI, the article notes their team works under export controls and sanctions, lacking full compute access, yet developed methods to "do a lot without very much." Chinese labs compete more fiercely with each other than with Silicon Valley, while being honest about trailing it. AI revenue is projected to end calendar 2026 between $185 billion and $190 billion, with 2027 potentially reaching towards $300 billion, though the range spans $250 billion to $350 billion. Enterprise adoption faces challenges as internal systems built on previous work-speed assumptions struggle when individuals produce faster, requiring system changes beyond just providing AI tools. Regarding market leverage, US banks' Tier 1 capital is "extremely healthy" compared to 2007, 2008, with leverage concentrated in hedge funds and broader investing, which borrow from a handful of banks and can unwind rapidly.
