Please answer the following question: Question: "Why were all electric computers seen as superioir to the z2?"  Context: "Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by German engineer Konrad Zuse in 1939, was one of the earliest examples of an electromechanical relay computer."  Answer:
Answer:
much faster all-electric computers
