Trust me. No self-respecting anybody sits there. Interesting comment about early CGI ray tracing; I was heavily into CGI (Alias/Silicon Graphics) in the early 90s. It was exciting to build virtual sets, position virtual lights, and have a virtual anti-gravity camera equipped with an excellent cine zoom lens. After five years of it, I got burned out and quit. Repetitive strain pain, debugging code, working in a darkly lit room all day, and a high ratio of difficult clients opened my mind to other options. ... It's remarkable how far the field has advanced in just 25 years.
