Thats a fun thought experiment at least. Is there any way for an AI to gain physical control on its own, within the bounds of software. It can make programs and interact with the web.
Some combination of bank hacking, 3D modeling, and ordering 3D prints delivered gets it close, but i dont know if it can seal the deal without human assistance. Some kind of assembly seems necessary, or at least powering on if it just orders a prebuilt robotic appendage.
