You can't just stop technological progress. Even if one country stops researching artificial intelligence, some other countries will continue to do it. The real question is what to do with the technology. You can use exactly the same technology for very different social and political purposes. So I think people shouldn't be focused on the question of how to stop technological progress because this is impossible. Instead the question should be what kind of usage to make of the new technology. And here we still have quite a lot of power to influence the direction it's taking.
