I'm not a fan of heights
The current tallest building in the world and structure ever built is the Burj Khalifa in Dubai, UAE (2722 feet). There are more of what is referred to as "megatall" skyscrapers being built and planned than ever before. These massive buildings are at least 600 meters tall. One notable currently under construction is the Jeddah Tower in Jeddah, Saudi Arabia. When completed it will be over 3300 feet tall or just over one kilometer. Two others planned are the Azerbaijan Tower, south of of Baku, Azerbaijan (3458 feet) and the Sky Mile Tower in Tokyo, Japan (5577 feet). The Sky Mile Tower is planned for 2045. I am really not a fan of heights or tall buildings. I feel the technology that makes them possible could be redirected for better use.
