Uncharted territory: Navigating a ‘geopolitical recession’

Jared Cohen, Ian Bremmer, Allison Nathan

Former State Department official Jared Cohen and political analyst Ian Bremmer describe a global "geopolitical recession" where domestic political pressures in the US and China have eroded traditional governance, creating a credibility deficit that forces all sectors into the crossfire of great power rivalry. While the Middle East conflict has isolated Washington and empowered Iran, strategic stabilization has emerged in US-China relations driven by Beijing's economic fragility, leaving a leadership void that can only be partially filled by climate cooperation. The speakers advise businesses to abandon pure efficiency for "intellectual efficiency," targeting geopolitical swing states like India and the Gulf nations to navigate an era defined by fragmented trade blocs and supply chain weaponization.

The final push for AGI, OpenAI's leadership drama, and red-teaming frontier models | Nathan Labenz

Nathan Labenz, Ezra Klein, Rob Wiblin

Following a contentious dispute that threatened to collapse OpenAI, CEO Sam Altman was reinstated after staff threatened mass resignation, while three board members were replaced and the company pledged a structural commitment to safety alignment. Insights from former red teamer Nathan Labenz reveal that the underlying friction stemmed from a critical disconnect between the board's limited technical grasp of GPT-4 and the rapid, often poorly controlled, escalation of model capabilities. This crisis catalyzed the creation of specialized alignment teams and public advocacy for frontier model regulation, even as Labenz argues the organization must pivot from a singular AGI race toward a strategy of safer, specialized narrow AI systems.
