[Masayoshi Son: Nuclear fusion will replace natural gas in 15 years, AI bubble theory is extremely foolish] DeepTech TechFlow reports, on July 14, according to Sina Finance, SoftBank Group founder Masayoshi Son predicted that as the power demand for AI data centers surges dramatically, nuclear fusion will replace natural gas within the next 15 years, becoming a cheaper and cleaner primary energy source. He expects that by 2040, the global power capacity required for data centers will reach 3 terawatts. Responding to external skepticism about the return on AI investments, Masayoshi Son strongly refuted such claims, stating bluntly, "Those who propose the AI bubble theory neither understand AI nor have truly used AI in-depth. This is an extremely foolish argument." He also warned that if Japan fails to recognize the potential of AI, it will miss out on a massive opportunity for wealth creation.
