A $1.5 billion deal between Microsoft and G42, a UAE-based AI company, has sparked concerns among US lawmakers who fear sensitive AI technology could be exposed to Chinese espionage. G42 has ties to Chinese tech and surveillance companies, but promises to adhere to new safeguards and stop using Chinese equipment. Lawmakers worry the deal could still give G42 access to advanced semiconductors the US wants to protect from China. The deal raises questions about balancing tech expansion with protecting sensitive technology, with some lawmakers demanding more transparency and scrutiny.
