Indeed, we have seen many instances of software that are well regarded as being works of art. Is the source code for that software somehow not art?
If you've ever been to a makerspace, those places tend to be ground 0 for engineering as art.
Some buildings are works of art, but there are plenty that are clearly not. I doubt anyone considers a typical big box store or a commieblock art. To me, all functional software is equivalent to a mass-produced building on art scale.
