Well, as long as humanity itself survives to 3021, neither English, nor Spanish, nor Chinese are likely to be gone. Even Quechua is likely to persist.

Languages of massive empires rarely die out; they might be transformed (such as when Latin gave birth to an entire family or related languages), but outright disappearance is typically not their fate.

The curious thing about English is that it gained a massive role after spending almost a thousand years of its previous existence as a niche language spoken on a small island on the edge of Europe.
