It's for sure he will be remembered in 4483. By this time there will have been a dispersion of mankind to other planets 'Mars...Moon..Ect whilst planet Earth recoups after mankind destroyed the atmosphere rendering it uninhabitabal.
Before the mass evacuation scientists invented a device that would echo sound around the universe and through this device information or music could reach everyone, no matter what planet they were on, everyone would receive the same accurate information.
Before the evacuation people had long stopped making music, so saddened were they at ignoring the early warnings of ' global warming' they felt they had nothing to sing about.
With everyone trying to settle into their respective homes it was decided to play some music to try to cheer everyone up, trouble is, by this time most of the music was so outdated that it would either bore people to death or get on their nerves.
'Thank Goodness For a Man Called Michael Jackson' his music is as fresh in 4483 as it was the day it was released. As soon as 'Thriller was belted out around the universe the people came alive, they started to sing and dance once more, happiness filled everyones hearts, Michael Jackson had left a legacy that would live forever. Children would read about this fine man in the history books, they would read of how he tried to warn the people about the damage that was being caused to planet earth, the starvation and suffering in third world countries and the extinction of wildlife everywhere. They would learn of all the good things that he done and of his own survival against all the odds, but most importantly they will learn that had it not been for greed then the world really could have been a better place.
So yes, in 4483 and beyond, people will know who Michael Jackson was because he 'Will' go down in History, his 'Legacy' will be etched in stone.
That is not fiction it is fact.
