Artificial intelligence is transforming how we discover and develop new medicines. But how far can it really take us? In this episode, Jacob and Saloni trace the path of drug development from discovery to testing, manufacturing, and delivery. They explore where AI could speed things up, and where it still hits the limits of biology, data, and economics. They ask what it would take, beyond algorithms, to actually cure and eradicate diseases.

Hard Drugs is a new podcast from Works in Progress and Open Philanthropy about medical innovation presented by Saloni Dattani and Jacob Trefethen.

[Minor correction: Since the 1980s, malaria challenge trials no longer involve hundreds of bites; in the past, volunteers received many bites for the exposure part of the trial rather than the challenge part.]
