The system, the organism or ecosystem of European civilization world wide is rotting and collapsing right before our very eyes. We are witness to the Technology Age Collapse, whether people can or want to see it or not. That will have consequences for everything and everyone, including Venice.
AI cannot create any of the things that formed the European civilization that produced and maintained everything we all have, like computers, electricity, communications, transportation, flight, etc. AI can copy, emulate, and automate; it cannot create harmonious and finely humanly tuned things. It would never have created the works of art and architecture, let alone the technologies to produce everything in order to solve specific human problems.
