The 2028 Global Intelligence Crisis

"What if our AI bullishness continues to be right... and what if that's actually bearish?"

A fictional-but-rigorously-researched macro memo written from June 2028, looking back at a financial crisis triggered by AI's overwhelming success. The thesis: AI exceeds all expectations, corporate margins explode, the S&P hits 8,000 by October 2026 — then the economy collapses anyway. Machines don't spend money. White-collar workers lose jobs and stop consuming. The entire consumer economy quietly implodes in what the authors call the "Human Intelligence Displacement Spiral."

Relevance to This Watchlist

▲ NVDA — owns the compute; the scenario's biggest winner▲ CDNS / SNPS — chip design demand accelerates throughout▲ TSM — foundry demand surges as AI compute scales▼ NOW — explicitly named as an early casualty in Q3 2026▼ CLS — hardware builder exposed to enterprise capex freeze
