The technological art emerging during the early part of the second half of the 20th century actively worked to take apart the paradigms that had supported the utopias of the old culture for over 5 centuries. This new art took over the construction and management of these utopias that had been developed for the industrial society by the artistic avant-garde during the first half of last century and replaced them with those for the digital-cybernetic society. Now, in the 21st century, we can finally analyze the utopias of technological art in historiographical terms. The article's authors provide their experience in the theory and practice, and as curators, managers and professors of new media and art in order to produce this highly needed, though to date non-existent, critical and self-critical analysis. The necessary distance and perspective that we now have allows us to finally undertake the necessary assessment of the level and significance of these utopias of technological art, and their evolution, fall or current validity.
