TL;DW:
Due to various molecular configurations (aka polymorphs), currently known medicines when contaminated with a catalyst seed molecule/particle can become unstable and irreversibly unreproducible via chained-contaminations.
This system of contamination and reproduction acts in similar fashion to viral infections.
Current Solutions:
- better clean room procedures for all steps of medicine manufacturing.
- pour more money into medicine polymorph research.
I am talking about the part in the video where they described the history of this effect while the scientific understanding of it was still developing, in particular the bit about how it caused church organs to corrode
Thanks for clarifying.
