I remember all the complaints about the use of graphing calculators during my early years as a math teacher. Today I don't hear anyone complain about them. Why? We have learned how to use graphing calculators to investigate graphs, curves, statistical data, and other topics that used to be very difficult or impossible to do without graphing calculators. We have also changed how we assess students. We create assessments that have sections to be completed without the graphing calculator and or where the graphing calculator makes no difference. In short we have adjusted to the technology and use it for the good it was intended for. According to the following quotes, lifted from the Teaching with Contests blog, educators have always been resistant to technological advances. 

“Students today depend too much on hand-held calculators.” (Anonymous, 1985)

“Ballpoint pens will be the ruin of education in our country. Students use these devices and then throw them away. The American virtues of thrift and frugality are being discarded. Business and banks will never allow such expensive luxuries.” (Federal Teacher, 1950)

“Students today depend upon these expensive fountain pens. They can no longer write with a straight pen and nib, (not to mention sharpen their own quills). We parents must not allow them to wallow in such luxury to the detriment of learning how to cope in the real business world, which is not so extravagant.” (PTA Gazette, 1941)

“Students today depend upon store bought ink. They don’t know how to make their own. When they run out of ink they will be unable to write words or ciphers until their next trip to the settlement. This is a sad commentary on modern education.” (The Rural American Teacher, 1929)

“Students today depend too much upon ink. They don’t know how to use a pen knife to sharpen a pencil. Pen and ink will never replace the pencil.” (National Association of Teachers, 1907)

“Students today depend upon paper too much. They don’t know how to write on slate without chalk dust all over themselves. They can’t clean a slate properly. What will they do when they run out of paper?” (Principal’s Association, 1815)

“Students today can’t prepare bark to calculate their problems. They depend upon their slates, which are more expensive. What will they do when their slate is dropped and it breaks? They will be unable to write!” (Teachers Conference, 1703)
