Fanciful thinking on elevators

So, architects, at least, are thinking about what could be done if elevators went away from steel cabled up and down things, to something more like the "go anywhere" deal on the Starship Enterprise.

All sounds very cool, but I would have thought that the destruction of the World Trade Centre, and recent London and Dubai fires, are making the idea of living or even working on (say) the 100th floor less attractive than ever.  Not sure that I had realised how high a building going up in Jeddah was going to be:

Today there is a 1,000-meter (167-story) building under construction in Jeddah, Saudi Arabia. Even taller buildings are possible with today’s structural technology.
