If you were to travel to just 50 years into the future, I doubt that you would even recognize our own planet.
Fifty years ago, I wrote a post similar to yours. It was the time of TV, the first PC and the Internet less than 30 years ago. The human has not changed. The pencil has become PC, tablet, mobile. The newspaper has become TV and tablet and information is faster. Many manual tasks have been automated. But humans always have feelings of love, of hatred. Humans always make war, corruption and great behavior of generosity.
Technologies change but not human behavior.
That is correct. Human behaviour doesn't change that much. But the world sure does!
