There were many lingua francas of which French was supposedly the first global lingua franca. That changed and it became English (from what I understand). We will probably see another language become the lingua franca, so my question is: should it be English? Are there better candidates out there? Why / why not?
Spoken English and written English are two different languages that have different features and different design flaws.
And one of the flaws of written English is that it has no spoken equivalent, haha!
