Technological utopianism is an ideology based on the premise that advances in science and technology will eventually bring about a utopia, or at least help to fulfil a utopian ideal.
19th and 20th century liberal thinkers like Karl Marx believed the power of technology would end the eras of kings and the church. The later association of the idea with eugenics and world war 2 led to the term falling out of favour for some time.
The rise of Silicon Valley anti-authoritarian counter-culture in the computing industry led once again to the idea that technology could increase personal freedoms and issue in an new era. Crypto-anarchists and affiliates such as Julian Assange would take the idea of technology as a tool against government oppression to its logical conclusion.
Critics of the idea cite it's lack of social policy and environmental concerns as well as the unequal access to technologies.
