The article and most HN comments here understandably talk about failed export control when the target audience is individual users. But export controls are actually fairly successful when their target is employees within a company. Go to an AI hardware company like Nvidia (or even Google which builds TPUs), and you’ll find that specific internal projects involve export controlled knowledge and can only be staffed by U.S. citizens, not foreigners. And employees naturally take this seriously without circumvention attempts because their job is on the line. This is the kind of quiet export control that stopped plenty of people successfully, but it’s just not visible to the world.
