It's been tried with Chinese Python back in the early 2000s: http://reganmian.net/blog/2008/11/21/chinese-python-translat...

It never really took off. I think because computers already require users to read and type Latin letters in lots of other situations, and it's not that hard to learn what a few keywords mean, so you might as well stick with the English keywords everyone else is using.

It might not be hard to learn the keywords in an English programming language but it seems hard to learn something like Spring Boot
