German computer pioneer Konrad Zuse discussed the mechanism of an feedback between computation result and executed program in 1983 in his lecture "Faust, Mephistopheles and Computer" and coined the term Devil's Wire. In the early days of computer history, the program to compute and the data to compute on was separated, nowadays computers use the same memory for both, so it is possible to write programs that manipulate their own program. Question, do we have already a Devil's Wire in our neural network based AIs?
