SoftBank's Masayoshi Son has publicly questioned Elon Musk's concept of orbital AI data centers, according to a report from the Wall Street Journal. The Japanese billionaire argued that the math simply doesn't support such a venture, asserting that the artificial intelligence race will be won on Earth within just a few years.
Son's critique centers on the economics of space-based computing. He pointed to electricity costs, which he claims account for only 7% of total operational expenses—a figure that undermines a key argument for moving data centers off the planet. The moonshot idea, often promoted by Musk, has generated buzz but faces significant practical hurdles.
This skepticism comes from a major player in the AI infrastructure arms race. SoftBank has aggressively invested in terrestrial AI compute, and Son's comments suggest a bet-the-company focus on Earthbound solutions. His public dismissal of orbital centers signals a sharp divergence in strategy between two of tech's most prominent visionaries.
The technology community remains divided on the feasibility of space-based data centers. Proponents argue that abundant solar energy and cooling benefits could offset high launch costs, while critics see astronomical logistical challenges. For now, Son is placing his chips on a more grounded approach, declaring the real battlefield will be won in conventional data centers.
Some analysts caution that Son's view may be influenced by SoftBank's existing terrestrial investments, potentially downplaying long-term innovations in space infrastructure.
