While Elon Musk’s xAI pursues a highly ambitious, $1.25 trillion plan to merge with SpaceX and launch orbital data centers by 2029, the company’s own foundation is cracking with the resignation of its fourth co-founder, Tony Wu, according to a TechMeme report.
Quick Summary
- •While Elon Musk’s xAI pursues a highly ambitious, $1.25 trillion plan to merge with SpaceX and launch orbital data centers by 2029, the company’s own foundation is cracking with the resignation of its fourth co-founder, Tony Wu, according to a TechMeme report.
- •Key company: xAI
- •Also mentioned: SpaceX
Wu’s departure follows the earlier exits of co-founders Igor Babuschkin, Kyle Kosic, and another individual whose name was not disclosed in the report from Bloomberg. This pattern of attrition among the founding technical team raises questions about the internal stability of the AI venture as it pursues its expansive goals. According to Bloomberg, Wu had been with xAI for less than three years before his resignation.
The resignations occur against the backdrop of an extraordinarily ambitious technical roadmap. As reported by TechMeme, Elon Musk's overarching strategy involves a proposed $1.25 trillion merger between xAI and aerospace manufacturer SpaceX. The central, and highly complex, technical objective of this plan is to launch advanced computing infrastructure into orbit, creating functional data centers in space by approximately 2029.
Industry observers cited by TechMeme have characterized this goal of deploying orbital data centers as "highly ambitious" yet "plausible," acknowledging the significant engineering challenges involved. Such an endeavor would require overcoming substantial hurdles related to power, cooling, and radiation hardening for sensitive computing equipment in the harsh environment of space, all while maintaining reliable, low-latency communication links with terrestrial networks.
xAI is the developer of Grok, an AI chatbot that is integrated within Musk's X social media platform. The company has positioned itself as a competitor to well-funded AI labs like OpenAI, Anthropic, and Google DeepMind. The loss of multiple key architects so early in the company's lifecycle could impact its ability to execute on both its near-term AI development and its long-term, space-based computational vision.
Neither xAI nor Tony Wu has publicly disclosed the specific reasons for his departure. The company has not released a statement addressing the resignation or its potential impact on ongoing projects. This lack of official commentary leaves the technology and business communities to analyze the implications based on the pattern of departures and the scale of the declared ambitions.
