The barrier to entry, or at least to proficiency is access to educational material and community. i.e. currently the necessary skill is to at least understand English. Adding an incredible amount of complexity to understand when something is a keyword or not, depending on the combination between any number of hundreds of natural languages, and worse live-translating keywords without ever messing up functions, variables, and methods is not going to make it better - if it did everyone would using visual programming languages.

Programming languages with different natural language keywords are useful learning tools, but they are basically training wheels on a bike, they need to come out at some point for someone to be good at it.
