I studied* Humanities Computer Science, as it was called at my university at the time. Behind closed doors, the professor was fairly explicit about it not being as world-changing, innovative or new as it was presented whenever they were seeking funding. Their work ranged from metadata tagging to version control to long-term digital archives.

In fact, he said the field had been renamed several times, largely to make it seem like a new field when it wasn't. Digital Humanities, Humanities Computer Science, and so on all refer to the same loosely defined field.

Although there certainly is something in it that isn't entirely nebulous, I'm not convinced "Digital Humanities" in itself, really is a thing or that the definition has any practical use other than providing a label when you seek funding.

*note: I was enrolled for a lengthy period of time and spent most of my time in university with their department and in the student association but I left without a degree.
