This causes the Mandela effect or the Universe A & B phenomenon.
The 20th century is real granular time, but the 21st century time is not granular and contiguous, instead it is flat and fake.
The 21st century does't actually exist.
The 21st century is just a digital parody of the 20th. Too many reboots across the arts and design, films and fashion. We're recycling the same stories and material.
If you think that we're moving into some kind of 'linear gleaming future' designed by Bob Geldof then think again. We're just experiencing scintillations of trends from the 20th century in a nostalgia spiral.
Follow this, the clothing and fashion from the first season of the Brady Bunch to the last is very different. It ran from the late 60s to the mid 70s. However if we saw someone from 2003 or even 1999 walking around today, we wouldn't be taken aback by their appearance or clothing style. Cars from 2004 don't look that different from cars from 2014... etc. If a pop music song from today was released in 2004 it wouldn't feel 'out of place', this is in contrast to past decades, for example by 1994 the 80s were already a nostalgic encapsulated idea, an era that had come to a close, there wasn't this leakage of it into the mid 90s with music and fashion, it was retro. You could throw an ironic 80s themed party for example... But how would you throw an ironic retro party based on 2004? It wouldn't feel retro at all.
Take the idea of a 'hipster' for example. their fashion sense is already an eclectic nostalgia of past decades all boiled down into a 'look'. Therefore there cannot really be a post-hipster, you can't parody a parody. We've reached some sharp end of an asymptotic curve, and are ready to break through the membrane into something else.
You see it all really began with Picasso, and the introduction of the modern aesthetic, which broke down the world of the Edwardian gentleman and his white man's burden. Certain end-points already occurred within the 20th century itself, the art and literature of the 20s and 30s for example has never been surpassed. As for modern art it peaked with Pollock. The 60s and the Moon landing represented the peak of modernism, after all what were the 1970s but a whining reprisal of the 60s? We were past post-modernism by the early 90s.
How can the 21st century be anything more than a digital parody of the 20th?
There is the pre-Ironic era ending somewhere towards the late 90s, and then the post-Ironic era after the millennium. This is an important point because notice that you can only remake/reboot pre-ironic art and styles, that is why all the big Film reboots are things like GhostBusters, Ninja Turtles and so forth. You can’t really reboot post-irony, say something from 2005 because it would be like a hipster parodying another hipster, it would be redundant. So there is this pre-irony innocence up until about the late 90s.
Approaching the actual Millennium is akin to Zeno's Paradox of the Arrow, or an Ant climbing up the side of a Pyramid without a Capstone. The false time of the 21st Century is the illusory distance that the arrow thinks it still needs to travel. Going half the distance each time, creates the illusion of the 21st century, and accounts for the tighter spirals of nostalgia, trends and reboots.
