Klaus Fuchs-Kittowski: Against the Power of Computers and the Destruction of Reason. For the Development of Human Creativity and Judgement. Remembering the Critical Intellectual Joseph Weizenbaum on the Occasion of his 100th Birthday tripleC 21 (2): 140-146 DOI: https://doi.org/10.31269/triplec.v21i2.1479 Abstract This article is a reflection on the relevance of Joseph Weizenbaum’s ethics today on the occasion of his 100th birthday. Today, there are many debates about the impact of AI technologies such as ChatGPT on society. Weizenbaum understood himself not as a computer and AI critic, but as a critic of society. He situated the problems of computing in the context of society. The paper shows that in the spirit of Weizenbaum we should also in the contemporary age of advanced AI remind ourselves that computers cannot understand, do not have feelings, and therefore cannot do many things that humans actively and consciously do. Klaus Fuchs-Kittowski is a German computer scientist and philosopher of science. He was a Professor of Information Processing at Humboldt University in Berlin. In 2022, he was awarded the Wiener-Schmidt-Price by the German Society for Cybernetics (Deutsche Gesellschaft für Kybernetik).
