The reality of English becoming the world's lingua franca will mean that people who are not native English speakers will also have a say on how the language is spoken.
From Wikipedia in "World Englishes"
When the number of bilingual English speakers, as it will likely be the case in this century, equals or outnumbers the ones in the "homelands" of English like the UK and the USA, they will soon start adapting the English language to their own worldviews and uses, and in fact they are already doing so, but they will do it with full confidence. For sure, speakers of "proper English" will complain, but what are they gonna do about it?
We will see some interesting developments in our lifetime.
It already has? India has the world's second largest number of English speakers already, far exceeding the UK and a little behind the US in first. Nigeria and Pakistan also have very large English speaking populations. This is only likely to increase as English offers social and economic mobility and becomes the defacto lingua franca for people with different mother tongues to speak to each other. Indian englishisms I really need the rest of the world to start with is prepone as the opposite of postpone.
