Boooo!
This is interesting to see
It’s official: we are building what will be the second-tallest building in the world. My father, Mirwais Azizi, was recently invited to appear on BBC Persia, where he revealed our plans to build a new tower in Dubai which will share the skies with Burj Khalifa and other skyscrapers in the city. This will mark a breakthrough achievement for the Azizi brand, and we couldn’t be prouder, especially looking back at our humble origins in Afghanistan, when my father started the company with $500 in 1989.
Nice! This will be great to see!! 
Based on these articles and the twitter tweet, there is a likely chance they’ll aim for surpassing not only Shanghai Tower, but also Merdeka 118 as the second tallest building the world.

This would spark some competition between this and the Binghatti skyscraper! 
Well, I’d be amazed if a megatall is finally not only proposed but built in New York. Dubai and skyscrapers this is not so my field of interest, because a skyscraper history like New York, Chicago and another U.S. city Dubai has not.
Dubai and New York are two of my most favorite cities. But yeah I agree, NYC has more skyscraper history than Dubai since NYC is much older. I do too, hope that a megatall would be proposed there as well 
I would like to see a mega tall in NYC in midtown/downtown
Over 700+ meters!
