AI Boom Hits a Fork: Slowdown Calls Clash with Capex Confidence as Markets Get Nervous
Dario Amodei's repeated calls for a global slowdown in frontier AI development, echoed by Microsoft's new humanist AI code of conduct and FTC antitrust caution, are being publicly rejected by Nvidia and Meta leadership even as hyperscaler spending draws fresh skeptical scrutiny (Wachter's analysis, Burry-style overbuilding worries) and weak guidance from Adobe and a post-slowdown-comment selloff in GE Vernova signal investor jitters.
