Through breakthroughs in core technologies and strategically precise promotion, DeepSeek has rapidly amassed a vast user base, sparking a “cyber carnival” phenomenon within the online sphere. This new norm of human-machine dialogue, enabled by generative AI technology, manifests a value orientation characterized by a shift towards “human-centric” in technical tools, reconstruction of “consensus-based cognition” in public cognition, and the development of “zero-marginal” fluidity in social interactions. However, it concurrently harbors latent risks and worries, including cognitive biases in technical decision-making and regulatory adaptation challenges, the predicament of human value erosion within digital fetishism, and the crisis of collective loneliness under novel social interaction paradigms. Therefore, it is imperative to reconstruct the new ethical paradigm of human digital existence driven by DeepSeek. We should pay attention to the proactive assessment and mitigation of technological risks, revival and redefinition of value rationality, and standardization and innovation of social governance. Such measures aim to achieve a balance between “carnival” and “order” in cyber interactions, thereby fostering responsible innovation in emerging technologies guided by the imperative of public well-being.
