AI Infra: A Stick Figure Field Manual
The entire AI infrastructure stack explained by stick figures: chips (HBM is the real bottleneck), clusters (NVLink, networks, and your wallet), the software layer cake (CUDA to PyTorch to OOM), inference (prefill + decode, buy vs rent), the training asymmetry, cooling and geography, and the electricity pyramid. XKCD-style black ink on white, guided by STICKY in a propeller cap.
