Why Saudi Arabia Is Building a Floating City

as an engineer, this project is just as ambitious as the LINE project ... also just as dumb & impractical as the LINE project.
I am a person first before an engineer so practicallity is more important than mega engineering works.
it is so much more easier to build the otagon full on land than half in the ocean furthermore it's the residential area instead of the port area kinda restrict the port from ever being fully utilized or expand. 
Remember first rule of thumb in housing ... industrial area does not go well with residential, it's either one or the other.
MBS is high on drugs and playing the sims all day everyday having ideas like this !
