Fair but I'd point out I also didn't make the algorithm that changes photos. I'm wrapping a bunch of algorithms that other people made in a way that makes them easy to use.

It's not just that GUI's are hard, it's that the "customer" base will inevitably be much less technical and I'd receive a lot more difficult to resolve bug reports. So no-gui is also a way of staying focused on more interesting parts of the project.
