Over time I have changed quite a lot
Begin as, I was young, after I was programmed, at that time, in 1936, from then on, by the 1940s, as time went by

Over time I have changed quite a lot. I started from a calculating machine . When I was young I could make difficult sums more easier. After I was programmed by a person who operated me. I could “think” reasonably . At that time it was considered a great change in technology and the start of a man-made intelligence. In 1936, a book written by Alan Turing said that I could work out any difficult mathematical problem. From that time on, I grew rapidly in size and in brainpower. By the 1940s I had grown the same size as a room. As time went by my memory improved, so I completely changed my shape. My memory became too large to make me believe it. since the 1970s I have many new usages. I have been used to make mobile phones and help with medical operations. I have been sent to learn about the Moon and Mars. Anyway, my aim is to give human race a life of high quality.
