Within 20 years of this interview (by approximately 2045), AI models will be able to predict how a drug affects the human body without physical testing, and will be more predictive than today's clinical trials.
“in 20 years we'll be able to know how a drug affects the body without ever actually testing it. And my prediction is actually our our AI models will be more predictive than today's clinical trials.” View on YouTube
This is an explicit 20-year prediction (to approximately 2045) made in 2025. AI drug-discovery/prediction tools are advancing but nowhere near replacing clinical trials as of 2026, and the timeframe has not elapsed, so this cannot be evaluated yet.
