Generic solutions like this rarely make any good results. Look at filterforge for eg. Some textures look decent but when you take closer look they have lots of tiny artifacts, they are ok as starting point to make good texture but nothing that is ready to use. Some goes for 3d models, i found great plugin to create rocks (or asteroids) results are very good for mobiles (you do not see uv artifacts in low res and without normalmaps), but those generated meshes would be terrible quality on PC with better quality shaders.
And what really annoys me is abuse of term “AI”, we did not create AI yet so how those guys can have AI generated meshes. They just made bit more complicated plugin for mesh morphing, and results are not that good. Nowhere near as good as army of asian 3d modelers.
Last thing, it goes for everything procedurally generated. Our brain always looks for similarities and everything procedurally generated will look SAME to us, because we seek those similarities, our brain kind of compresses it all under single label. So usually instead of “unlimited” procedurally generated variations is better to have around 5 versions that are human made and do not look similar. I do not think i have seen anything procedurally generated that was not boring, well maybe few aspects of spore, but that game flopped because of procedurally generated content (or rather lack of anything else besides it).
