Living in sky scrapers sucks and is not enjoyable. Same with living in suburbia. The sweet spot is densely packed urban areas that are built on the human scale.
living in skyscrapers is no different than living in any apartment building, except the larger number of apartments with nice views.
what modern skyscapers are doing wrong is putting in only large-footprint high-end retail (like department stores) on the street level, or nothing at all. A zoning change to require small retail stalls at the street level would go a long way to making cities more livable. And all those people living upstairs generate a lot of foot traffic to help all sorts of businesses thrive. (what I'm talking about overall is what makes midtown NY so unpleasant compared to other NYC neighborhoods)
It is different. if you are very high up there is too much wind for a balcony and you have no relationship with street life (people look like ants). 5-stories aka Paris-size is human scale, anything much taller isn't. The higher the floor, the less frequently people leave their building.
