today you no longer need to be as brilliant as John Carmack to achieve success, and John Carmack himself will be the first to tell you that. Where John was sitting in a cubicle by himself in Mesquite, Texas for 80 hours a week painstakingly inventing all this stuff from first principles, on hardware that was barely capable, you have a supercomputer in your pocket, another supercomputer on your desk, and two dozen open source frameworks and libraries that can do 90% of the work for you. You have GitHub, Wikipedia, Stack Overflow, and the whole of the Internet.
