Why drug development costs a billion dollars

November 13, 2026 · 1 h 24 min

Show notes

Computer chips have become dramatically cheaper over time. But the opposite seems to have happened in drug development. Since at least the 1950s, it’s become more and more expensive to develop new drugs. Scientists have coined this trend Eroom’s law.


In this episode, Jacob and Saloni investigate Eroom’s law. Why has it become so much more expensive to develop new drugs, despite massive technological advances? They chat about penicillin, CRISPR, billion-dollar research failures, and whether the last decade has been a turning point. Can AI help reverse the trend? Listen to find out!
