At present, how high can we go when building skyscrapers before the laws of physics deems it unsafe ?

What technological hurdles do we face to go say,  TWICE the height the worlds tallest buildings ?  If we are to make 'Super Sky Scrapers' what technological implementations are required to achieve this ?  Is it feasible to even build scrapers so big ? do we have a choice given the frightening rate at which the planets population is increasing ?

    there is no upper limit, if we can find materials strong enough.  Read up on "Space elevator". We could build a structure up to and  beyond geosynchronous altitude, 35000 km.

    5 miles.

    We're getting close to the practical limits.  It isn't just about designing materials that can withstand the stresses - put enough money and materials into a structure and it can withstand truly astounding things.

    But the top of a tall structure still has to be useful.  Those spaces need climate control, water and sewer, fire suppression, etc.  They need access - you can only safely and comfortably run an elevator so fast, imagine needing to travel hundreds of floors.

    Building vertically isn't the answer to our population issues.  Space is not the issue, there are vast tracts of uninhabited places all over the world.  We consume resources in a very inefficient manner.  We have to find a way to reduce our demands on the environment - more sustainable agriculture, less meat production, less waste in general, sustainable energy production (this is the big one).

    Well, the Burj Khalifa is 828 meters

    Maybe they want to attract terrorists?

    "do we have a choice given the frightening rate at which the planets population is increasing ?"

    Yes we do. Making girls go to school long enough tends to lower the birthrate. We could build new (preferably walkable)  cities in the desert. Some countries like France and Spain have entire villages without inhabitants, China has entire cities

    I'm not a building engineer by any means. But certainly if you had a foundation of a square mile that's a half mile deep you could build at least a mile high. With today's materials. Which is of course ridiculous......
