OpenAI Exec Quits After Brain and Body Demand Separate AI Projects
KEY POINTS
- •Fidji Simo left her role as OpenAI's head of product after a worsening chronic illness forced her to take medical leave in April.
- •OpenAI president Greg Brockman temporarily took over product responsibilities while Simo shifted to part-time advisory duties.
- •Simo, who joined OpenAI in 2025 after leading Instacart through its IPO and spending over a decade at Meta, expressed renewed interest in AI for health.
Fidji Simo, once Meta's decade-long commander and Instacart IPO navigator, joined OpenAI in 2025 to turbocharge the AI empire beyond just fancy algorithms. But things took a turn in April when she tapped out due to a 'severe exacerbation' of Postural Orthostatic Tachycardia Syndrome (POTS) — a condition with a name that sounds like a particularly sad robot uprising. OpenAI President Greg Brockman stepped in to pilot the product ship while she moonlighted as a part-time advisor. Sam Altman’s heartfelt X message was basically heartfelt code for 'this sucks'. Simo, tweeting that she'd failed to quit many times before, now eyes AI in health with fresh eyes and presumably less dizziness.
