Actually I am more a less some Pessimist, but still tho, I can just fully agree on your observations. Life is full of circles and even if you are able to understand them, they are quite difficult to predict. Whenever humans look into the future they see a lot of visions. Some are come true, some others are some decates later just funny.

As a younger one, its often very entertaining to see some Scifi from the 60th. All that strange stuff people expect humans would life in the future. I am pretty sure that in 60 or 70 years everyone will look at us and smile the same way. How could they just believe in THAT?

So I personally really like to share thoughts with older people. Because with their stories the past is more than an echo from the past, but become suddenly closer, often more painful, but always more understandable.

Even if it currently looks not that well in the world, don't even dare to think that its the last depression you might see. As a pessimist i am pretty sure there will be a lot more you can expect ;)
