Absolutely Nothing.
It has been a hundred years since something interesting happened. Experts and scientists mistakenly predicted that humans would continue to evolve and become more creative with technology by their side. They have, instead, turned into dull creatures. Predictability and monotony are the proper characteristics to describe our modern human being. Their quality of life turned into something disappointing, as they slowly stumbled down from their pedestal of epicness into their current aridity. They abandoned their curiosity and abruptly turned into indifferent beings with purposeless lives.
By November 2018, the last human achievements were carried out, among them the discovery of immortality - the one cause for human’s decline into their insipidity. Humans were blinded by their abusive nature. One peek - one scent - of immortality, and they were inescapably drawn by its dangerous beauty, its wholesomeness, its promise for a life-changing adventure. By the end of 2018, humanity had already yielded to immortality. It was spread like a disease - a curious one, as a fact; an epidemic that didn’t kill, but kept you from dying. Which was worse, in so many ways.
2019 was the first year in which absolutely nothing happened. No more scientific discoveries needed to be made - they were not of immediate urgency anymore. Diseases required no cure, for they were no longer a threat. Funnily enough, when humans abolished death’s unpredictability, they turned the rest of their lives into a predictable set of events.
