Transhumanism: A Cult for Our Times?

This article explores whether the transhumanist movement exhibits cult-like characteristics. Using Robert J. Lifton's eight criteria for identifying cults, the author analyzes transhumanism's information control, mystical manipulation, purity demands, confession culture, sacred science, loaded language, doctrine over person, and dispensing of existence. The author argues that transhumanism displays similarities to cults in its closed-mindedness, exclusionary practices, and apocalyptic salvation narrative. While not geographically centralized, transhumanism's online communities foster strong group identity and suppress dissent, showcasing blind optimism towards future technologies and devaluation of non-believers. The article concludes that the future trajectory of transhumanism will depend on whether its technological predictions materialize and how its adherents react to reality.

US Restricts Swiss Access to AI Chips: A Tech Cold War?

The US has excluded Switzerland from unrestricted access to AI computer chips, prompting criticism from Swiss Economics Minister Guy Parmelin. This move limits Swiss academic and corporate access to these vital components, placing Switzerland in a category with restricted imports. Parmelin stated this is incomprehensible, as the ETH Zurich utilizes these chips for innovation crucial to the US, making this a potential “own goal” for America. Negotiations are underway to secure unrestricted access. The US aims to prevent rivals, particularly China, from obtaining this technology and circumventing export restrictions. Separately, President Trump's announcement to forgo the global minimum tax will have consequences for Switzerland, impacting the federal government, cantons, and businesses. The Swiss government will consider reciprocal measures.
