It is an intellectual trap to believe that just because a skill you worked hard to achieve is no longer necessary, you are a "better person" than those who no longer need that skill.
Can you use a slide rule? I bet you can't. But when pocket calculators were invented engineers were scornful of a new generation who could only punch in numbers. Can you write in assembly? Probably not, but when higher-level languages first turned up you weren't considered a "real" programmer unless you could hack assembly -- and then again when Java overtook C, and then again when interpreted languages like PHP overtook Java.
Why does having memorized an API make you better than somebody who uses a tool that makes memorizing the API unnecessary? Unless you can show that one makes you demonstrably more efficient, it's immaterial.
