Maybe I am a naysayer, but John Carmack is going against other companies and teams with not only billions in funding for hardware and data, but also with big staffs of experts. Not only are people who have been in the research for a while more likely to have good ideas, but having the support of engineers to write tests and data wrangling, Neuroscientists to bounce ideas off of, and a whole bevy of support staff is just more likely to produce results. I'm also not a big fan of the kind of hero worship of "well he wrote Doom, so this should be a cakewalk." I'm not saying he won't, but he probably won't. What am I missing here that everyone seems all hyped up about?
