(If you know enough to consider the question, draw the "technology tree" sometime that has everything necessary to create a web browser and a network to use it on. Don't forget the routers, the concept of a Turing machine, compilers, hardware, time to learn how to optimize the hardware, AND gates, OR gates, XOR gates, pipelines, caching, hard drives, RAM, fiber optics, modems/network, protocols, standarization, display technology, the science behind all of this stuff, input technology, time to test the technology, the list just goes on.)
