You are correct that the AI industry has produced no value for the economy, but the speculation on AI is the only thing keeping the U.S. economy from dropping into an economic cataclysm. The US economy has been dependent on the idea of infinite growth through innovation since 2008, and the tech industry is all out of innovation. So the only thing they can do is keep building datacenters and pray that an AGI somehow wakes up when they hit the magic number of GPUs. Then the elites can finally kill off all the proles like they've been itching to since the Communist Manifesto was first written.
