Well, its true the syntax of CoffeeScript is trivial, and coming from Python background myself I find it very easy to comprehend. But I also find Javascript fairly easy to work with and to be honest I rather work on my target language without the abstraction of another (at least in the case of JavaScript). Take the javascript issues covered in the presentation - they are not hard to work with as long as you treat them as part of the Javascript package (for example, var your local variables to make them local. not hard to make into a habit).
