I’m also thinking a shift to residential and mixed use would be the way to go here. They also need invest in better architecture to make this into an attraction that would support business focused around entertainment.
They should hire Stefano Boeri and build another Vertical Forest building such as the one in Milan. It would be a statement, not one about height but about nature.
Simply imagine this at LY, it would be a slam dunk and would for it very nicely:
