So if it's not such a huge barrier for a foreign programmer to program in an English-centric computer programming language, surely the same can be said about non-Arabic speakers who might want, or have to deal with this language?
It's the same reason why Chinese developers haven't banded together to create a Chinese-based language. They still code in Chinese, but the languages and libraries they use are mainstream: C++, Java, Python, ... All of these languages support arbitrary Unicode in comments and Java and Python also support Unicode identifiers. As a result, Chinese documentation is available even for software that's otherwise in English. However, if you tried to convince Chinese developers to abandon their battle-tested languages with a rich ecosystem for some other language just so they can use different keywords, you'd get laughed out of the room. It's not solving a problem they have.
That doesn't mean that localized programming languages can't be useful e.g. in education. But translating documentation and libraries is useful for many more people than translating the syntax of a language.
Your comment is an argument against any new programming language.
[0] Disclaimer all the Spanish/Arabic/etc words were pulled directly from google translate.
[1] Though Arabic is particularly rough because the shape of the letters change based on the letters around it so you have to learn that too! See: http://www.arabion.net/lesson2.html
What I think may be more useful for bringing more people into programming in their native language would be thinking about providing transliterations where, for example, the Python keywords are translated into Arabic. Doing that Arabic speakers could write in their own language and English speakers could run a utility that maps from the Arabic keywords to the current standard English keywords. Stuff like variable names gets a little tricky there I'll admit, not sure how to handle them, maybe Romanize them too?
