Prospective jurors are questioned about AI views and express strong feelings toward Elon Musk and technology.

Summary

OpenAI Condemns Musk

OpenAI called Elon Musk’s lawsuit a harassment campaign motivated by ego, jealousy, and an intent to slow a rival.
Musk’s xAI lab, now part of SpaceX, introduced the Grok chatbot in 2023 and said any award would be redirected to OpenAI’s nonprofit arm.
Analysts say the case could reshape AI market dynamics, with a court ruling expected by mid-May that may set precedent for governance of hybrid AI organizations.

History

Historical Context

After the U.S. Department of Justice sued Microsoft in May 1998 for bundling Internet Explorer with Windows—an action that led Judge Thomas Penfield Jackson to order remedies and later a $899 million EU fine—the case set a precedent for tech antitrust enforcement. Elon Musk’s $134 billion claim against OpenAI invokes that legacy as regulators again scrutinize dominant AI platforms.
