Court documents tied to Elon Musk’s lawsuit against OpenAI CEO Sam Altman have disclosed previously unknown details about cooperation between OpenAI and Microsoft. Altman proposed a larger partnership after OpenAI’s Dota 2 bot beat a professional gamer in 2017, seeking about $300 million in Azure computing support. Internal emails showed skepticism and concerns about OpenAI turning to Amazon. Microsoft later invested $1 billion. The Verge reported ties are now less close.

Even if quantum computing advances, symmetric-key encryption such as AES-128 is not a realistic target for attacks, a claim said. Cryptography engineer Filippo Valsorda, who maintains the Go programming language’s cryptography standard library, said quantum threats should distinguish between public-key and symmetric-key cryptography. He said Shor’s algorithm threatens asymmetric systems such as RSA and ECDSA, while Grover-based attacks on AES-128 remain extremely costly. He also urged focusing resources on replacing Shor-vulnerable public-key cryptography.
