Will we ever run out of phone numbers?

Will we run out of phone numbers?
Yes we will, by some time this will definitely happen but we have just enough time to fix the issue. 
Here are my alternatives:
ID's like 123456789-+@ 
Pros:
Almost infinite
Easy to read 
Cons:
Easy impersonation(with symbols like I(uppercase I)and |(dash up) 
Can be tricky to remember
Usernames like @wateraddict4
Pros:
Easy to read
Mediocre hard to impersonate
If allowing up to 20 symbols almost impossible to run out
Cons:
Can be tricky to remember if long
Hard/Impossible to type on old phones with rotary

Crypto wallet addresses like
UQB-r4a-X3g-gon3LaIwbhfOHCZSxZYsx6RhCCwVT0AH87no
(@random(on telegram) devs crypto address)
Pros:
Infinite!
Cons:
Impossible to remember
Impossible to type
Impossible to read
QR codes, barcodes and similar
Pros:
Infinite!
Cons:
Non typable
Non remberable
So in total I think that we will never run out of phone numbers not because we will run out but because they will be too outdated in future technology.
