I see it as a remarkably good thing that engineering (and to some extent science) has standardised so much on English and I can only hope that all other walks of life will as well.
It would be so nice if everyone on earth spoke excellent English.
As another non-native: ditto. Free English courses for Portuguese-speaking people would be more beneficial I think. (Why free? Well the Portuguese site is free too.)
How is one or even a thousand persons' inability to learn another language an argument for how science should be practiced?
As technologists, maybe we could find solutions that, ya know, don't force massive, life altering requirements on billions of people?
It's not hard to speak at least two languages and one of them should be English.
There is no solution as good as the whole world being bilingual.
I remember in uni taking "German for technical and scientific reading" courses just for that purpose. It make much more grow the communities than shut most people out because they don't speak English.
But while people don't learn English (what takes years), they shouldn't just stop all their other learning.
My personal wish is that children be taught English early enough so that this doesn't become an issue. I am quite grateful I started when I was 5 or 6.
