Being presented with information and answers to almost any question you might have is certainly useful, but deeper knowledge and understanding takes learning and practice. Why bother learning how to add or multiply when you have a calculator? Teachers have had to patiently explain this to us for many years, and mental arithmetic and general life skills will reassure us later on that this was, actually, a good idea.

Learning to code gives you a tool for solving problems, and this tool can be applied to many different things. Understanding how the tool works gives you the power to change it, adapt existing solutions, and figure out new and better solutions.

If I travel to a country where the locals speak a different language, I can grab a few key phrases to say my "please" and "thank you", but if I need to live there then I will likely need to be able to say a lot more. Imagine being a car manufacturer, putting out a new model designed for getting around the town. You call it the Nova, then discover that in Spanish it translates as "it doesn't go".

Whether you're making a game or making a web application or similar, having code that works is one thing, but understanding how it works gives you the power to change things, adjust, and be creative in how you approach a problem. And when you're fluent in programming, much like fluency in a language, you can be creative and make your ideas a reality.
