If I must be honest, I do not think that the bitcoin will be used by everyone in 2022, we cannot also not predict this either but its just something that I do not see happening these days.
The bitcoin has a great future a head of course but I do not think that other currency's will me less more used.
I think everyone already knew that it would be difficult for bitcoin users to be able to have everyone in the world, it is very improbable, even fiat takes a long time to be used by everyone, hundreds of years ago
