Currently at the Royal Museum of Fine Arts in Brussels, in cooperation with the Louvre in Paris, until 24/01/2016 you can see the exhibition "2050 - A brief History of the Future".
Based on the book "Une brève histoire de l'avenir" by Jacques Attali, which was published in 2006, you will find about 70 very different artworks ranging from paintings, sculptures, photos and videos to installations and digital art. There are some big stars involved like Andy Warhol, On Kawara, David LaChapelle and Andreas Gursky, to name but a few.
None of the art pieces were made especially for this show so you might have already seen some of them in former exhibitions or even during the Brussels Art Days a few weeks back.
I must also admit that I did not always understand the link between the works on display and the connotation regarding the future but I can say that there are a lot of extremely fine pieces to be seen and the exhibition is definitely worth a visit. Do make sure that you have ample time though as this is nothing you can/should visit in 25 minutes.
If you are not in a rush and would like to visit the show while being given a word of explanation instead of having to read through the numerous pages distributed throughout the exhibition yourself... I am considering organizing a guided tour here in November.
