Yeah but doesn't the way you intone a word change the meaning entirely? With how heavy accents are the norm for English second speakers I would think this makes Chinese practically impossible to learn to pronounce. Also 90% of the world can read the latin alphabet already which is a good start when learning a new language. Years ago I made a small attempt to learn some Russian and Cyrillic was like smashing against a brick wall, I imagine it's 200x worse for Chinese since you have to learn 5000 new characters.
