Seven Wonders of the Modern World?
The Seven Wonders of the Ancient World documents the most remarkable man-made creations of classical antiquity.
What are the seven most remarkable man-made creations of our present world?
I think that would depend a lot on definitions. Do systems count as "man-made creations"? Does the Internet? (although even if it does it is debatable if it is among the top 7) Or are we still in the realm of looking for locations/buildings/artworks? Does it include old stuff that's still around and was impressive to build at the time, or are we looking only for "modern" things?
The Seven Wonders are not just creations, there are buildings. The closest to this kind of wonders may be space stations like ISS.
SpaceX. Just think how used we are now to rockets landing by themselves.
