That's the point I'm trying not to make. Are you building a startup that's effectively a CRUD app? If so, sure, that's pretty much all you need and is why coder schools have become so prevalent - they get you to a practicing point that covers the bases of most small websites and very, very basic startups.
Age and experience brings with it something vital: the ability to build long term pattern recognition of technology business cycles, the "all is old is new again", the ways that novel technologies may fall like their predecessors. This is not something you learn in a CS program or even a few years out of college. It's something you only learn by playing with tens of languages and mastering six or seven over decades, by constantly learning, by being part of those business cycles. This skillset is often discredited and is enormously valuable, but I believe it requires a tireless passion for novelty and modern technique to become a multiplier on skill.
