Once I told the management to have them learn English because it's almost mandatory for a software engineer to understand English as much as an aspiring Go player would learn Japanese. But the management told me back it's _harsh_ to require them to learn anything more. Harsh? Huh?
That said, I found the need for technical books real, and translated several English books (including Programming Erlang) into Japanese. However I know this effort will not scale and these days I am inclined to abandon translation and tell them that English is just another tool you have to learn to survive.
But you are right that within the Indo-European language family English does not seem to be one of the more complicated languages. Which might have something to do with its origins as a pidgin of French, Anglo-Saxon, Frisian and Danish.
Btw, if anyone is wondering, I am not a native english speaker. But I did learn how to program by reading the books and documentation that were available in english. If I had waited for somebody to translate these to my language, I probably wouldn't know a thing about programming to this day.
