When considering Artificial Intelligence with the concept of "long time", it’s essential to develop a critical distance by stepping back from the immediate, short-term impacts of AI. This approach asks us to examine AI’s role in human history and its long-term effects on society, ethics, and labor. A critical view of AI over "long time" forces deeper reflection on sustainability, potential biases, and how this technology might influence future generations. This temporal distance encourages slow thinking and thoughtful regulation, ensuring that AI’s integration into society is deliberate and balanced rather than driven by speed or short-term profit.
