SoftBank's Masayoshi Son Questions Elon Musk's Vision for AI Data Centers in Space

Elon Musk plans to launch data centers into orbit by 2028, believing that space-based facilities powered by nearly unlimited solar energy will be key to advancing artificial intelligence. This vision aims to address the soaring electricity demands of AI systems and the environmental and infrastructure challenges faced by terrestrial data centers. However, Masayoshi Son, CEO of SoftBank and an early investor in Alibaba and AI technologies, expressed skepticism about Musk's plan during a recent investor meeting in Japan. Son questioned the practicality of space data centers, emphasizing that electricity costs are only a fraction of data center expenses, with the majority spent on chips, hardware, and computing systems. He highlighted the significant maintenance challenges of facilities hundreds of kilometers above Earth and argued that the AI race will be decided much sooner than the decade it might take to develop space infrastructure.

The disagreement reflects a deeper strategic divide: Musk advocates for solving foundational problems even if solutions seem initially impossible, as demonstrated by his work on reusable rockets and electric vehicles. In contrast, Son focuses on near-term investments in AI models, chips, robotics, and existing data center infrastructure, aiming to capitalize on the imminent trillion-dollar AI market. Despite their differing approaches, both billionaires share the goal of controlling the infrastructure that will underpin the AI revolution. Musk pursues this through SpaceX, xAI, and Tesla, while Son invests in OpenAI, Arm, and global computing infrastructure. The central question now is not whether AI will transform the world, but who will first establish the infrastructure to power it.
