Tom Yeh is an Associate Professor of Computer Science at the University of Colorado Boulder and the creator of AI by Hand, a wildly popular educational newsletter and community that teaches transformers, LLMs, and deep learning architectures through pen-and-paper calculations. With 62,000+ Substack subscribers, 200,000+ social media followers, and a Feynman-inspired philosophy that you only truly understand what you can build by hand, Yeh has become one of the most influential voices in practical AI education - bridging the gap between black-box hype and genuine first-principles understanding.
Russ Cox is a Distinguished Engineer at Google and the longtime technical lead of the Go programming language, the open-source language he helped shape for over a decade. Known for foundational work on RE2 (a safe, linear-time regex engine), Plan 9 from User Space, and Go's module system, he bridges deep computer science theory with production-grade engineering. After stepping down as Go tech lead in September 2024, he shifted focus to AI-powered open source tooling - building Gaby and Oscar, agent systems designed to help maintainers with the unglamorous but essential work of keeping software alive.
