A competent modeler can make these types of meshes in under 5 minutes.
I don't think this general complaint about AI workflows is that useful. Most people are not a competent <insert job here>. Most people don't know a competent <insert job here> or can't afford to hire one. Even something that takes longer than a professional do at worse quality for many things is better than _nothing_ which is the realistic alternative for most people who would use something like this.
As a machine learning engineer who dabbles with Blender and hobby gamedev, this is pretty impressive, but not quite to the point of being useful in any practical manner (as far as the limited furniture examples are concerned.
A competent modeler can make these types of meshes in under 5 minutes, and you still need to seed the generation with polys.
I imagine the next step will be to have the seed generation controlled by an LLM, and to start adding image models to the autoregressive parts of the architecture.
Then we might see truly mobile game-ready assets!
