It is an interesting question to propose and strong opinions can drive this to one side (humans made this technology, therefore we are in control) or the other (technology can run itself and then eventually robots will take over the world). For myself, I think technological agency begins with the human intentions for that technology, but the technology starts to shape its own agency as different elements of the technology begin to come to light and as it gets pushed to a limit.

I like your programmer example because I think it ties in with the idea of pushing limits from last week. Sure, a human programmer was in charge of setting up the program how it should be used, but the ability of the program to do much more past “the guiding period” contributes to its agency. The people at Adobe would prefer you use Photoshop for pictures and graphics, InDesign for publications and Premiere for videos, but Photoshop has elements that can make motion pictures. Human intention would tell us that it is silly to use Photoshop for motion pictures, but the processes and extensions in the program to push its limits allow to do so.
