You will die at the hands of a synthetic virus that targets specific genomes with fatal precision. AI has already created it, humans will deploy it, it's just a matter of when now.
It's up to you to figure out who and when, but there won't be any fireworks, or any glamorous ending, it wont be universal, targeting only specific people and also it will be intentional, because it is necessary for you to die for others to thrive. That is nature.
