Why Arabs are building those Colossal Towers?

Burj Khalifa, Dubai

The Torch, Doha

Westbay,Doha Downtown

The 828-metre (2,717 ft) tall Burj Khalifa in Dubai has been the world's tallest building since 2008. The Burj Khalifa has been classified as Megatall.
I am no expert in eschatology but one of the signs of Hour, which has appeared and which the Prophet Salalahu Alayhe Wasalm spoke off, is competing in building and adorning their houses after having been barefoot, naked, shepherds.
 Umar ibn Al Khattab Raditala Anhu narrated - Hadeeth which speaks of Jibrael and his coming to the Messenger of AllahSalalahu Alayhe Wasalm and questioning him about Islam, Emaan, Ihsan & about the Hour that the Prophet Salalahu Alayhe Wasalm told Jibrael about the signs & said "When the slave woman gives birth to her mistress and you barefoot and naked shepherds compete in the construction of lofty buildings" (Recorded by Muslim)
Quran 27:16 says, "And Sulaiman (Solomon) inherited (the knowledge of Dawood, David). He said "O mankind! We have been taught the language of birds, and on us have been bestowed all things. This, verily, is an evident grace (from Allah,God)"

Desert dwelling shepherds competing in building lofty buildings to show off. King Solomon's kingdom was also very advanced in technology. Not only Quran speaks off but Bible and Torah also. Hazrat Suleiman's followers could open portals. Had elm of metaphysics, energy of light and time machine and. Moving physical matter from one place to another (the throne of Queen Saba) How much are we using these technologies? What is or purpose to make higher towers?
