"Jim Keller Challenges Sam Altman's Trillion-Dollar AI Chip Ambitions"

Renowned chip designer Jim Keller criticizes OpenAI CEO Sam Altman's plan to seek $8 trillion in funding for AI semiconductor ambitions, stating that he could achieve the same goals for less than a trillion dollars by focusing on architectural enhancements and supply chain improvements. Keller's company, Tenstorrent, is working on AI-based chip architectures and recently partnered with Samsung Foundry to develop next-gen RISC-V-based chiplet designs. Industry experts, including NVIDIA's CEO Jensen Huang, question the feasibility of Altman's ambitious plans and emphasize the importance of architectural changes in addition to production volume increases in the semiconductor industry.
