Mega yachts are designed using CAD software, the prototypes are milled or even sometimes now 3d printed out of huge foam panel. Advanced hulls are constructed from a number of materials and methods. All of these things required bespoke skilled labor that cannot be replaced with robots or AI. I think mega yachts are stupid, that doesn't mean they shouldn't exist and to act like they are the same as even 20 years ago is willfully ignorant
