Hell, my wife told me a story, she was a new undergrad at MIT and the new residents in the dorm were hanging out in the lounge getting to know one another. They got on the topic of foreign languages since there were a lot of kids from other countries or who had traveled fairly extensively, and when one boy was asked how many languages he knew, he replied, "computer, or other?" which drew lambasting from his fellow nerds at arguably one of the nerdiest universities in the world.
Computer languages are not interpersonal communication languages, and they should not be treated as such. That doesn't mean that I necessarily agree with the foreign language requirements for college admittance (ie, if EVERYONE is supposed to go to college at a given school whether they actually should or not, then foreign language is taught to the lowest-common-denominator and no one learns it well) but treating things that aren't spoken or written human languages as such is stupid.
I live in Montreal. Came here after age 40 from Englishville (Toronto Ontario). At that time Montreal was 60/40 French Engilsh in ratio. Today it is 80/20. I decided to immerse myself into the French language, which took me three years to really be comfortable. Comfortable means, understanding and laughing at jokes and participating in meetings and thinking in French.
My own children are bilingual as are my grandchildren. The grandchildren's public school program was for 4 years of French immersion -- all teaching in French, except gym, recess and lunch hour). Thereafter, it is half day in French, and a half day English.
At home we watch TV in either language and speak English to each other.
There is a benefit to the brain to having a second or third language. I cannot say exactly what it is, but I think it is because French/Spanish is a Latin Language, we have to think differently. And in being faced with technical problems, I quickly think of alternative technical solutions and consequences to problems. Is it because of the second language? I think so. But jokingly, my work associates say my proposals are presented faster in time than an I/O interrupt. And the proposals are solid solutions.
Eliminating a second language is in my opinion, narrowing your brilliance, your ability to think "out of the box", to broaden your knowledge, and most of all, to realize that there is no exclusivity on intelligence. Those second and third language students have a thinking and comprehension advantage over the unilingual individual.
