Death and Life in Silicon Valley: retirement talk by Erik Lindholm, one of the pioneering graphics hardware engineers at SGI/NVIDIA. Covers his childhood, work at SGI/NVIDIA, his contributions to T&L, programmable shader HW, unified shader HW and creation of CUDA.
One of the best engineering talks I've seen in quite a while. 5/5 highly recommended.
