Looks like the generated wireframes are still terrible and would need to be redone by hand. So no need for artists to worry about their job security just yet.
1. Unless we're strictly talking about static meshes (such as for scenery), building out the rigging/animation for garbage topologies is going to be absolute hell.
2. Your performance POV was for ONE mesh, but if your quad/triangle count is 10x higher than it needs to be, how well is it going to scale particularly on low-end gaming platforms?
3. Lighting/shadows/reflections can produce some pretty UGLY effects when your surface polygons are a mess.
