There's one thing worse than "designed by AI" and it's "designed by committee".
I wish more buildings were designed by AI. There's so much depressing architecture.
What you really need is more people willing to pay a premium to live/work in a unique or famous building like the empire state building, and then more such buildings will be built.
Hopefully with AI we will make things like stonework and indoor plasterwork, hell, even indoor statues, that much cheaper, and we can start creating beautiful places to live.
