So logically, we can only strengthen the international system, limit the risk of technology abuse and conduct more predictive measures, to get the drop on blowing the malevolent people. Briefly, we need a more sensitive global governance and the high-tech panopticon as he said. Taking pre-emptive actions on assumed threats may be a high-risk matter. It is certainly correct that Professor Bostrom will set off this debate around how to protect our fragile world from technological turmoil. The future deserves our protection.
