However if they made a "Penny" once, they can most likely do it again. Penny describes herself as the "world's first synthetic person capable of generating an Aura," meaning there may be other synthetic prototypes out there ready for upgrades. Either way, the technology does exist in the current time and if Ironwood manages to somehow avoid the ethics department, those like Penny could be made. Even if Penny has a human brain in her head that makes her existence possible, I'm sure others could be found to volunteer for the "upgrade."
