Hardware Automation and AI Agents Compress Software Moats

tengyanAI · x · 2026-08-05

AI researcher tengyanAI argues that software moats are being compressed from both directions. Better hardware, such as Rubin, automates more low-level scheduling and optimization, while AI agents automate software engineering itself.

As software optimization becomes machine-handled, competitive advantage shifts back to physical metrics like memory bandwidth, HBM capacity, and power efficiency. In a quoted thread, they also elaborate on why "megakernels are dead," explaining how the Rubin architecture resolves straggler CTA issues, eliminating the need for manually writing massive kernels.
