Are there bounds to procedural generation ?

I for a moment considered a builtin algorithm for the procedural design of a chair in blender. Then I realized this is not possible: A chair has many vertices and edges which have to mesh in specific ways in order to be recognizable as a chair... and then to be textured and uv unwrapped.

And though uv unwrapped textures can be procedurally generated, and though 99% of meshes can be ultimately textured -- procedurally generated uv unwrapped textures can't infer a mesh. (Right?)
