Outlook for Global Growth: Less Synchronized, More Complicated

Jan Hatzius, Alison Nathan

Federal Reserve Chair Jerome Powell signaled a November 2021 announcement for asset purchase tapering while Goldman Sachs lowered its 2021 U.S. GDP growth forecast to 6% amid rising virus cases and global supply chain disruptions. Despite revising core PCE inflation expectations upward to 3.75% for the current year, the central bank anticipates the spike will remain temporary and defer rate hikes until potentially mid-2023. This cautious stance aims to balance the risk of new viral variants and the expiration of unemployment benefits, which together are expected to drive approximately 1.5 million additional jobs by late 2021.

Jaron Lanier: Virtual Reality, Social Media & the Future of Humans and AI | Lex Fridman Podcast #218

Jaron Lanier, Lex Fridman

Jaron Lanier argues that virtual reality serves primarily to refresh human perception of the physical world rather than replace it, while asserting that artificial intelligence consists only of subservient algorithms lacking true morality or consciousness. He critiques current social media and cryptocurrency models for exploiting cognitive vulnerabilities and avoiding democratic engagement, proposing instead a "data dignity" framework where data unions and shared stakes restore economic agency to individuals. Ultimately, Lanier advocates for anchoring human meaning in mortality and direct experience, rejecting technological solutions to death while urging a future where kindness is learned through hard lessons rather than automated incentives.

How To Take Full Control Of Your Mind: Prof. Steve Peters, The Chimp Paradox | E96

Prof. Steve Peters, Stephen Bartlett, Steve Peters

Professor Steve Peters presents the Chimp Paradox model, which distinguishes between the emotional "Chimp," the rational "Human," and the value-based "Computer" to explain how modern isolation and social media exacerbate mental dysfunction. He offers actionable strategies such as factual rebuttals, specific grieving protocols, and the management of seven fundamental drives to help individuals harness their internal brain systems rather than suppressing them. The framework culminates in his workbook *A Path Through the Jungle*, which guides users in building resilience, correcting self-image deficits, and taking full responsibility for their psychological well-being.
