RE: Why quantum computing is a threat now even though it is may be 10 years away

Yes, encryption that is not quantum-proof should really only be considered temporary encryption. And we really don’t know when quantum will be able to break modern encryption methods. Could be 10 years, or 20, or 5.

I was at a conference a couple years ago where the head of quantum for Microsoft gave an update on the state of the technology. Most of the limitations are purely engineering, not theoretical.

We know everything we need to know, we just need better ways to build the machines. Most of the needed advances are in material science. And I have no doubt that the recent advances in AI will fuel some of those needed material science advances.
