>>1397635>80% of the whole worldThat'd leave about 1,532,822,593 people. That would essentially reset the population to 1875AD levels. So, -143 years of population removed, if you will. That is about as many people as what the population has increased since 4chan was created. If you killed 80% of the population, there's a chance that only those persons born since 4chan was created would be left.
