I predict that landline....

[Silverobama]

I was chatting with a friend at an English club. We talked about the disappearing of the landline phone nowadays. Ten years ago, we still used them but now less and less people use it. Later I said:

Does your home still have a landline phone? I predict that landline phones will altogether disappear within future five years.

Are the sentences good?
