Elon’s AI Phone is coming (Ad)

Rumors are swirling that Elon Musk is developing a new mobile device that could rival the iPhone. It's said to be thinner, longer-lasting on battery, and cheaper to produce, with the ability to work worldwide without relying on cell towers. Former Bloomberg reporter and SAC Capital trader Josh Baylin says the evidence is mounting. He notes the FCC recently gave Musk a green light connected to his mobile plans, adding fuel to speculation. Baylin previously called the smartphone boom in 2004 and predicted Apple would sell a billion phones when others expected a fraction of that.tc pixel
