US arrests tech CEO over alleged $300M Nvidia chip smuggling to China

US authorities arrested a tech chief executive accused of smuggling about $300 million in Nvidia chips into China. Ars Technica notes that arrests over chip smuggling keep occurring.

Why it matters: Repeated prosecutions suggest export controls are leaking at meaningful scale, which raises pressure for tighter chip tracking and enforcement. It also feeds the debate over whether restricting hardware slows Chinese AI progress or just creates a black market.
