I think it's actually detrimental. You will lose opportunities if you stick with any language but English for programming related things. Your translations won't be perfect. You won't be able to communicate with people in other countries. You will miss new important developments and discussion all of it happening in English. It's just much more efficient for everyone to swallow the pride and accept English as the language of programming/computer science.
I am not a native English speaker. I am not very talented when it comes to learning languages. It took me many years to be able to understand written and spoken English. Still I am very grateful that once I got there the whole world is open to me. I can read every important publication, participate in discussions and read code other people write. Doing it in my native language is just putting artificial barriers out there. It doesn't make sense. Learning about computer science in my native language just makes it less efficient and introduce problems like quality of the translation or terms lacking necessary context and usage patterns (as there is less published in that language).
I feel efforts to translate to other European languages will be detrimental to general level of education and communication in future businesses. Publish only in English, it forces people to learn it. It's better for everyone in the end. If you know you had to learn it to be a competent programmer or scientist or other IT specialist you will and by doing so you will contribute to removing barriers that exist in EU which Americans don't have to deal with. I believe it's one of the big advantages US IT sector has over Europeans.
