TL;DW:
Due to various molecular configurations (aka polymorphs), currently known medicines when contaminated with a catalyst seed molecule/particle can become irreversibly unreproducible via chained-contaminations.
- the contamination can cause the existing configurations to become more stable in a negative fashion where the medicine/compounds no longer work they way we expect them to.
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.
It is tin pest, an autocatalytic transformation of tin, and it is absolutely in the video and related to the topic (see Lvxferres comment). Just to calm down everyone who wants to get angry about clickbait before having watched the video.
Private equity still generally sucks tho.
