I have a friend who is a centenarian. We recently discussed the many technical and other developments that had become a normal part of our lives. Most had not been predicted when my friend was born in 1920.
Just some of these:
+ Radio (once known as the Wireless)
+ The Internet
+ Supersonic air travel
+ Nuclear power
+ CT and MRI medical scans
+ DNA analysis
There are many more that could be named, which takes me on to the next question: what will happen in the next 100 years? Scheduled space travel and colonising the moon is an easy one to predict, but what else? Almost certainly, there will be developments that we would not have considered possible today. After all, my friend would never have thought that he would be able to sit in front of a device watching live moving pictures from around the world. And in high definition colour.
Whatever the future holds, I won't be around as a witness unless there medical developments are imminent that will allow me to live forever. Perhaps that will be a good thing because not all developments will be beneficial for the planet and those who inhabit it.
