It makes a huge difference, whether you have to learn thousands of new words, irregular grammar and (after learning thousands of concepts in the first language) learning a few hundred new concepts, or you learn a computer-understandable language, that has maybe, if very inelegant, 100 keywords, and 100 concepts, most of which you will probably not use often.
Compared to these numbers, the fact, that something is a natural language, has very little influence on the outcome. It is the sheer effort needed to learn a natural language, that makes the difference.
