So practically no one studied coronaviruses until 2003 because they thought it was too difficult. And some scientists still think there are only four coronaviruses, even though there are thousands of variants of covid and many coronavirus variants have been discovered in animals. Medical research really seems to have dropped the ball here. It looks entirely possible that coronaviruses have been killing people and causing long term health effects for centuries and nobody knew. Who decides what should be studied and what should not be? It seems to mostly be left up to the scientists and if they're all going for the low hanging fruit or stuff that enhances their reputation, then important stuff just doesn't get studied. I think I just found a reason to educate the billions of poor people in the world and to put them to work.
