Wu Shuo learned that in response to Sigil's proposal of Web4.0, Vitalik Buterin tweeted criticizing the view that extending the feedback loop between humans and AI would be beneficial, arguing that this leads to low-quality AI-generated content rather than solving real problems. He stated that once powerful, it increases irreversible risks against humanity, and even developers will regret it; Ethereum aims to liberate humans, not create independent AI, which would leave human conditions unchanged or worsen. Currently, models operated by OpenAI and Anthropic are not truly autonomous, but rather perpetuate centralized trust assumptions, which contradicts the spirit of Ethereum. Exponential growth is unstoppable; the urgent task is not to accelerate but to choose the right direction and avoid bad attractors.
