The tech is impressive, I don't think we can deny that, but there are multiple reasons why people usually call it AI slop. For instance, AI-generated meshes tend to have bad topology, the kind that makes editing or fixing issues extremely difficult, meshes I would even consider unusable. You really do not want to use those meshes in bigger projects as they have often too many polygons. The first mesh has overlapping polygons in the corner, and it's a very small mesh, so it doesn't need to have so many polygons. The boat wasn't the worst, but I noticed topology issues at the bottom also. There are a few other things I could talk about from a technical standpoint, but another important point in world creation is optimization, and I really doubt the tech is far enough to handle those kind of things, like batching, atlasing, lod, occlusion, reducing overdraw etc. So, it's impressive, but not something I would use, and honestly, I enjoy playing around with Unity, so I don't want to prompt an AI and let it do the world-building for me. My latest world took me ~8 months, and I still enjoyed working on it, and once I released it, it really felt like I accomplished something. (The mirror button in your world doesn't seem to work?)
