We do need to have 300 other languages to have an equal facility as that of anyone having English
With English someone can communicate with enough individuals of those using any of the 300 languages.
With any other languages but excluding any English there is not that facility.
So others learning the one language of English is far more logical and rational than us learning multiple other languages yet still having compromised lingual ability.

Having lived outside of the UK for almost 50 years now, in many lands, and seen this problem from both sides, I disagree. I do see how you are thinking, but you are thinking theoretically, but not practically.
Its a harmless error to make here on Pedelec, but an error nonetheless.
Another thought, over the next few decades, its eminently possible that Chinese (more than one language of course!) will start to overtake English in general usage, our children and grandchildren, and their advisors, should keep this possibility in mind.....
Cantonese is fairly easy to learn and has the advantage that it is written easily with the normal alphabet we all know, and spoken widely over China and other countries like Singapore and Malaysia.
I picked up quite a lot in the 60's, but its mostly gone now, as I did not keep it up properly.....
Anyone, under 40 years old today, might be very strongly affected by such changes in the world with regard to languages.
Having more than one language to converse with, kept me in well paid technical jobs in the computer industry, entirely with US companies, once I left the RN.
So I have no regrets, and I also know the advantages as well...
American companies have great difficulty, generally speaking, in finding technical staff with a wider fluent range than just English and Spanish.....
