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.
Other currencies were never a hurdle in the way of success for bitcoin, but still it does not seem possible that by 2022 everyone in the world will start using bitcoins because bitcoins is still too new and it has a long way to go still, it already spent almost 9 years and it is still not being used by a third half of the world.
It depends on the amount of the funds investing in the digital currency. If there is limit, then the altcoins wil compete for the investment.
