In very early 2020, when I was following the news of the virus development in Wuhan, China, I felt like a conspiracy theorist pointing out to friends and coworkers that a bad epidemic spreading in one of the most crowded parts of the world. They thought it was ridiculous to say that hospitals were getting overwhelmed, people were being quarantined etc. Don't even think about suggesting it'll spread outside of China, or that the virus may have come from the lab that just so happened to also be in the origin of the epidemic, a lab which specialized in highly infectious diseases.
Not even 2 years later and where are we now? The entire world got sick and pretty much every country has done lockdowns/quarantines/shutdowns. Not to mention the lab theory of the virus origin still can't be ruled out.
Even after the pandemic started, people still had no problem sticking their head in the sand. It's not a big deal; it's 2020, we have technology and medicine and we'll just make a vaccine and get back to normal. Well now it's almost 2022 and somehow things just keep getting worse.
We can reasonably say the Black Death killed 30% of Europe's population. We can't reasonably say covid won't do the same. All optimistic projections so far have been proven wrong, so all we can say for sure is that humans are terrible at predicting the future.
