This depends on you. If you want it published, you should look to do so soon... The longer you wait, the more it appears to be based off real events and not your imagination. As Mark said this isn't a bad thing, but as you commented, it appears you want it to be as abstract as possible. This would mean you need urgency to keep the abstract... abstract. Depending on how similar they are, you may end up needing to remake the story which kind of really stinks but you need to weigh out what is most important to you. If you want that unique view on the future, this is a topic that requires the story to be finished quickly. The future is constantly evolving, constantly changing. What seems crazy today is normal tomorrow, and what seems normal yesterday is crazy today. If you are okay with the story as is, then I wouldn't worry about it too much. Of course, most of this also depends if you want to publish or not. Try not to get too hung up on it though, people care about good stories. Most stories have been re-written, re-worded, modernized, new theme same plot, 1000 times and people still read/watch. In the end, it isn't so much the content as much as your ability to deliver that content in a way that people find enjoyable.
