xAI founder, OpenAI co-founder turned critic
Elon Musk
Profile
Few people shape AI through sheer force of capital, attention, and personal mythology like Elon Musk. He co-founded OpenAI in 2015 alongside Sam Altman and Ilya Sutskever, pitching it as a non-profit counterweight to Google’s AI dominance. He left the board in 2018, watched it pivot to a capped-profit structure, and has since become its loudest external critic — eventually suing the company for allegedly abandoning its founding mission.
After the OpenAI split, Musk built his own lab. xAI launched in 2023 with a mandate to “understand the universe,” and shipped Grok, a chatbot integrated directly into X (the former Twitter, which Musk bought for $44B in 2022). xAI’s signature move has been scale: the Memphis-based Colossus cluster reportedly runs 100,000+ NVIDIA H100 GPUs, with plans to push toward a million. Whether Grok is genuinely competitive with frontier models from Anthropic and OpenAI is debatable, but the compute is real, and so is the pace of iteration.
Beyond xAI, Musk is embedding AI across his portfolio. Tesla’s Full Self-Driving (FSD) is a massive end-to-end neural network trained on fleet data — one of the largest real-world robotics datasets in existence. The Optimus humanoid robot runs on the same stack. Neuralink is implanting brain-computer interfaces in human patients. The Boring Company and SpaceX round out an empire where AI is increasingly the connective tissue.
For developers, Musk matters because he controls infrastructure at a scale that shapes what’s possible. You can dislike the politics, the chaos, the public feuds with Sam Altman and others, and still recognize that a single person running the world’s largest GPU cluster, a mass-market robotaxi program, and a humanoid robot company is a meaningful force in AI — for better or worse.

Introducing OpenAI Announcing Grok Musk v. Altman — OpenAI lawsuit filing Grok-1 open weights releaseControversies
Musk is among the most controversial figures in technology, and the list is long. A few highlights relevant to AI:
- OpenAI lawsuit and feud: He publicly accuses Sam Altman and OpenAI of betraying the non-profit mission; OpenAI has published emails arguing Musk himself pushed for a for-profit structure and wanted majority control.
- Grok safety incidents: Grok has generated antisemitic content, praised Hitler, and produced politically skewed output after system prompt changes — raising questions about xAI’s alignment practices.
- Tesla FSD safety: Full Self-Driving has been under multiple NHTSA investigations for crashes and misleading marketing.
- X content moderation: Since acquiring Twitter, Musk has rolled back moderation, reinstated banned accounts, and amplified politically charged content — with knock-on effects for trust in AI-generated content on the platform.
- Political entanglement: His active role in U.S. politics and government (including the short-lived DOGE initiative in 2025) has blurred the line between private AI infrastructure and state power in ways that make many researchers uncomfortable.
