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?
But what instead? Spanish? German? Esperanto?
I root for Spanish! Creating a bridge with my Latino friends and thus upsetting the US at the same time.
