Not even this film could predict...
...the crazy need of toilet papers. There's always that factor of the unpredictability of the human stupidity.
On the more serious note: They scientifically researched every aspect of this film to make it accurate, and they figured out that the hand sanitizers gonna be out, the media paranoia, the believers of the vaccines, the right masks, social distancing, fake cures (they failed at drinking bleach, but again, human stupidity is unpredictable)
Only other thing (next to TP) didn't happened now is the looting and the armed robberies. I wonder is this because in the film the virus was faster and a bit more deadlier than COVID?
