In my childhood in the 70's and 80's, the view of the world was very marked by the consequences of World War II. There was East and communism on the one hand and democracy and freedom on the other. NASA's lunar program was still in fresh memory and the development of computers happened at a rapid pace. Then the wall fell to the east all saw a common future towards the turn of the millennium and beyond. But something happened to the seeming and understanding of democracy. Russia fell back to the soviet era and in the United States became a convicted criminal president and will force the world to play by his rules. Fortunately, free Europe and the rest of North and South America were united so that his ideas had the most damaging effects in his own country.
It's been years and the world has changed for the better. Everyone can still remember the economic consequences for virtually the entire world, with the United States probably no one right now forgets the "second great depression". The world is once again working together to solve our common challenges. And yet it worries if the story is remembered: If we do not permanently defend and fight for not only our own freedom but also the freedom of others, democracy will quickly come under pressure. And I'm still waiting for a flying car and space tourism. However, the new computers are impressive even though there are very few people who can really understand how they work. They're almost human.
