No I do not think that it will get used by everyone in 2022, we can also not predict this too but I do not see it happen..
I think we are still very far from it and there are a lot of other currency's too.
We are riding on the same lane. I do still thinking that bitcoin will be used by everybody on 2022, it is still very early and people especially third world countries are very far from it. I guess the world will be ready within 50 years of bitcoin existence if it is still standing and not being replaced by new currencies or destroyed by the quantum computers.
