One of the big things being researched is composite cables which are considerably lighter than the steel cables that are currently used. As others have stated the weight of the cables becomes a major issue an extremely tall elevator shafts. Composite cables greatly reduce this problem and allow for taller elevator shafts using existing technologies.

Actually Kingdom tower will use Kone Ultrarope elevators,which in theory could support a main elevator shaft of up to a km although in this case the main shaft will be "only" 660m tall. "True" Km tall towers with floors to the roof is on the horizon.

This is what I spoke of a few pages back about Carbon Fiber being the future of elevators. I have a Poker buddy that works for Shindler, which is located about 5 miles away from my home. They have been working with it for about 5 years now.

Yeah I echoed the same post earlier. It'll be Ultrarope or something similar for now, but for the mid-term future / long term, it'll have to be a different technology.

Jeddah's Kingdom Tower will be taller than any other structure ever built. At more than one kilometer high, this supertall will require feats of engineering that, until now, have been the stuff of science fiction. Like the world's tallest, longest, and fastest elevators—which are being developed in a mine shaft in Finland.

Also these elevators unlike traditional ones dont get more(or only marginally so) expensive the taller you build your tower,incentivising developers to build taller and taller buildings.

The video explains it better

These are the 3 most obvious reasons but there are also many others.
And the reason you state are most likely why they are used only during construction, and not for the main lifts in a completed building.

Yeah, very "pointy"

For me even this building in the eastern Europe has more "point" in it's "design"
