I can definitely understand that perspective - an algorithm is not going to be able to compete with a human creatively, and if you want a nice, tailored experience it's not going to give you that. But I think it's a stretch to say to never use it. For one, someone who isn't confident in mapping could use it as a jumping off point. Sure, the maps will feel pretty same-y (among other things), but maybe they will complete something they otherwise would not have. And if they just use the random maps with no changes, well, then they will get a bland game. If someone wants their game to be aesthetically pleasing, unique, and polished, they will have to get their hands dirty at some point regardless of if they start from scratch or from a generated map.
I kind of think of it like a spark for creativity, rather than it's replacement. It's no substitute for handmade maps, but you can take the output and enhance it, maybe certain generated features inspire a better, more human-touched version with a similar layout, etc. Even if you don't use the maps at all and just get ideas for your own for maps made from scratch, it can still be useful. But I do get what you're saying.
Personally I just enjoy working on it for my own amusement, but I do hope people get some value out of it.
