That's not true though. I'm not familiar with C++, for example, but it doesn't look like gibberish when I look at it. Nor does Go, as another example, even though I've never written a line of it.

CoffeeScript, on the other hand, still is hard for me to parse—even as someone who has written thousands of lines for it.

There are very real differences in readability between languages.
