How Elon’s Empire Ends (and how to profit) (Ad)

Marc Chaikin, the 60 year Wall Street veteran whose Chaikin Money Flow indicator sits on every Bloomberg terminal, says a new micro cluster AI technology could render today's data centers, including Elon Musk's Colossus in Tennessee, obsolete for major breakthroughs. These next generation centers use 99 percent less space, electricity and water, yet Chaikin's research shows they could be more than a trillion times more powerful than the top data center on earth today, potentially cutting AI breakthrough timelines from five years to five days.tc pixel
