In the last few years we've seen: - The plot to kidnap Gretchen Whitmer - The Storming of the Capitol and pipe bombs left at the RNC and DNC - The break-in to kidnap Nancy Pelosi and the brutal on Paul Pelosi - Multiple assassination attempts against Trump - The assassination

🚨 NEW PAPER 🚨: Embodied AI (EAI, such as self-driving cars, AI-powered drones, humanoid robots, etc.) is here, but our policies are dangerously behind. We analyzed the risks from these EAI systems and found massive gaps in governance. 🧵

@apsrjournal Check out the article here:

How do countries mitigate the political costs of being accused of violating international law? In a new article in @apsrjournal, Tyler Pratt and I show that denying facts and challenging the applicability of law are effective strategies. IOs can counter-message though! (1 of 2)
