This is one of John Carmack's great skills. Over the years he has steered the entire industry towards improving itself. He's probably sent thousands of emails to Intel, Microsoft, AMD, NVIDIA, OpenGL, etc. He's one of the greatest driving forces in computing advancement. Millions of people upgraded their computers from 1996-2001 almost exclusively to play his games. He's probably responsible for more sold NVIDIA and Intel chips than any single person outside those companies.
