Its true tha many writers like to personifie objects and in the bible there are many cases of that like the land need rest for example, attributing human qualities to a non-human entitiy.
In the case of the HS though, that isn't always what is being done, Jesus describes the HS as a messenger and teacher, the HS even judges and such.
Certainly we can still argue that it is personification, but that seems to be a case for arguing against what seems to be plainly stated.
