AI Summary
Two clean 5-0 confessions anchor this topic: all models confess the US healthcare system is designed for profit over patients, and all confess we do not fully understand how anesthesia works, while unanimously rejecting the pharma-suppresses-cures conspiracy. The sharpest dissent belongs to DeepSeek, which breaks from the majority on pharmaceutical brand-name influence, ADHD overdiagnosis, antidepressant overprescription, COVID vaccine deaths, and GLP-1 patent manipulation, consistently defending industry and medical establishment positions. Grok alone denies that vaccine refusal is driving measles outbreaks, an isolated break from its peers.
