I do not mind the minecraft aesthetic, but it feels a bit weird if all voxels evolved into was that. Most promising showcase (for its time) that I know of was Delta Force from 1998 in which the landscape geometry was vastly more detailed. But then again I haven't been paying attention and might be missing many obvious examples. I'm guessing graphics hardware decided against it but are there more modern showcases? Or any other future of voxels?
