There certainly are some valid use cases. But the current usefulness/energy consumption ratio is pretty dreadful, and from my point of view it's future is not looking very good either. If energy was free, then who cares; otherwise I think it's legitimate to question whether the valid use cases of a few thousand people (total shot in the dark here, numbers appreciated) is worth using the same amount of electricity as Argentina, a country with 45M people.
