According to CoinMeta, in an interview with William Joy, Sun Yuchen stated that the development of AI algorithms and the risks associated with quantum computing have made him more bearish on Bitcoin than before. He believes that the industry and investors who hold Bitcoin through ETF have not fully taken into account these related risks. Furthermore, with advancements in AI in the field of mathematics, it may not be necessary to wait for a breakthrough in quantum computing for the risk of cracking existing cryptography through classical computing to emerge.
