Story idea, based on the idea that whatever "Future" that a time machine travels to will be dictated by the life and expectations of the Time Traveler - A scientist from Victorian times will come to a very Steampunk future, a traveler from the 1920's will come to a silvery art deco future, a 1950's person will come to Buck Rogers, 60's is all cheesy Star Trek/Doctor Who stuff, 70's is silver pajamas, 80's is Apocalyptic Wasteland, 90's is all Cyberpunk...
...Get the drift? My own personal vision of "The Future" has changed four times over the course of my life, and depending on what year I leave from will determine the "Future" that i arrive in.
So the story revolves around four men of different ages who meet in a bar and quickly discover that they are all the same person at different ages, yet none of them remember having had a time machine before (60-year-old Scientist knows that's him at 40-years-old across the table from him, yet he has no recollection of this happening to him when he was 40). They each, in turn, describe "The Future", each contradicting the next with their own version and having a spirited debate over which future is the best future.
In the end, it's a race through time where each one of them tries to get to The Future first and ensure that THEIR future is the one that survives, but NONE of them were correct because The Bartender got there first and The Future looks just like the year they left.
From their inability to accept the ideas of each other, The Future never happened.
