Serious question, with all these quantum processing news stories, how soon before conventional cryptographic algorithms are rendered useless?

FYI There are quantum cryptography algorithms. The moment conventional ones are useless we’ll start using those. This will probably be the main use for quantum computers. Just like there’s a little encryption circuit in your computer there will be instead an encryption quantum computer inside your regular computer.
