I think the title should have been: When it's difficult to learn a new language, why is that? Some paths are easier than others so it really depends on the new language and where someone is coming from. I started with PHP/JS on a self taught basis. Then I started to develop interest in other languages. Python was a no-brainer, C++ looked quirky but okay, in Java most thing looks familiar. But functional languages get me. Rust is another beast, but totally looks tamable. Haven't finished the article yet, but it has some great insights.
