The seventies were a more representative time for technological hopes, during a time when it was not yet clear which are the right technological choices. The nineties were a time of rapid technological progress, but most of it was perfectly predictable, without surprises. The only thing that was surprising during the nineties was how important the Internet became in practice, even if the evolution of its underlying technology was not surprising.

The time correctly delimited by you was the time of the greatest false political hopes, when everybody around the World believed that we got rid of the communist blood-sucking parasites and now the World would become that which had been described for decades in the propaganda of the Voice of America, where the political elites are held accountable for their actions, so if they are bad they are replaced through democratic elections, and the bad commercial companies are eliminated by competition in the free market.

Instead of this happening, already a couple of years before 9/11 a wave of destructuring many important historical companies happened, followed by a huge wave of mergers and acquisitions that has continued until today and which has eliminated competition from most markets, so that they are now dominated by quasi monopolies. Then the democratic elections have brought to power worse and worse human beings, all of whom have been much worse than some citizens that would have been randomly selected for those positions.

Nowadays, the economies of USA and of the other "Western" countries, and also their political institutions, resemble much more those of the socialist countries that they mocked during the seventies, than those of USA and W. Europe of that time.

So all the hopes of the nineties were naive and none of them was realized.
