Predict the future, harachelovek

During the celebration of the 75th anniversary of the Artek pioneer camp in 2000, a capsule was opened with a message from the pioneers of the 1960s to the 2000 Artek camp. The message was signed by 1200 Artek residents from all the republics of the Soviet Union, then it was put into a capsule and sealed in a metal rocket, which was stored on Kostrovaya Artek Square for 40 years. At the solemn line, the missile was sawn and a “letter to the future” was extracted from there. Pioneers of the 1960s suggested that in 2000 all the peoples of the earth live in peace, people fly to the moon, and Artek already has its own cosmodrome.

The post is inspired by the picture from the movie Back to the Future 2, which depicts 2015.
It is noted that people tend to make mistakes in predicting the future, and in the direction of significant exaggeration of their own or global achievements.
This was repeatedly confirmed in the predictions of futurologists and science fiction writers. Our brain is able to easily predict the future for a short period of time, but a range of several years is an impossible task for it. Why are we exaggerating progress?
I would like to conduct a little experiment to better understand this phenomenon. There are a lot of intelligent educated people on the habr who are well acquainted with the development of modern technologies.
The essence of the experiment is this: if you are interested, make your forecast in any field of science and technology for a year, three or five years.
Over time, we will see how many people were close to the truth, and how many were mistaken.
Well, I’ll make the first forecast on which the fate of the experiment depends - the geek magazine should last the next five years)
