I think it's hard to cure illnesses that have 2,000 different sub-categories and 300 sub-reasons and a genetic component.

I think this means: we still don't know. And I also think a well working novel therapy could wipe out the profits of companies selling common therapies that then are inferior.

IF, hypothetically, there would be a not patentable cure - would companies say: ok, it works, we will forgoe this business now? If it's multi-billion dollars?

Does someone share my concerns?
