Earthscrapers, or the concept of earthscrapers, is quite old. In fact, humans lived in deep caves, hundreds of metres high, well before building the first huts. And even before that they had already started to dig up the ground. In his book Civilizaciones bajo tierra (2017) (Underground Civilisations), Juan José Revenga talks of the underground city of Derinkuyu (Cappadocia), which had some 20 underground levels. Obviously, modern buildings were not yet there.
