English is the language of science and trade on the whole, which I think can be a good thing for the aforementioned reasons in your comment. Makes it much more universal.

I was on a trip in Spain, where students from all over the world came to learn Spanish. There were Americans, Japanese, Germans, etc (others I may have forgotten since this was during highschool!), but the gist of it is that everyone spoke their mother tongue, but the only unifying language there was Spanish. It was incredibly interesting speaking to someone who only knew Japanese and Spanish, where I only knew English and Spanish. People would talk to their friends in their native language, then relay what they said in Spanish for everyone else. It was mindblowingly cool to have a universal language to an otherwise insurmountable language barrier.

This also happened, somewhat annoyingly, in other parts of Spain. You'd be eagerly trying to practice Spanish, and spanish people would hear your accent, and would automatically switch to English for you. Same thing happened all across the world whenever we traveled. I always marveled at just how many people would switch to English whether we were in Germany or Zimbabwe.

I agree. I speak English very well now, but it is a weirdly hard requirement for a lot of jobs/hobbys in life.

You are interested in psychology? Awesome, go study psychology.
You are interested in physics? Here is a two year English course. You're bad at languages? Well, sucks for you.

I am wondering how much of an economic advantage it is for English speaking countries to have English as the base language of science. I bet at least 5% of students in other countries will not get as good as they could be because they are lacking the understanding of the language their study material is written in.
