Ask A Genius 1569: Aging Brains and Universes

The interview between Scott Douglas Jacobsen and Rick Rosner weaves together aging, politics, media bias, climate risk, AI, and longevity science. Rosner rejects simplistic claims that Donald Trump shows obvious dementia, instead using cosmology metaphors to describe how real Alzheimer’s compresses a person’s “information universe.” They discuss the Supreme Court’s refusal to hear Kim Davis’s challenge to marriage equality, underreported mass death and displacement in Sudan, and the racialized lens of Western news. Rosner warns that climate-driven migration and unregulated AI could destabilize democracies even as Western per-capita emissions fall, and he outlines his favored supplements: fisetin, curcumin, and metformin.
