That was pretty interesting. I was expecting cost/benefit on adopting quantum computing, which I suspect isn't going to be terribly useful to the everyday person soon. But it was refreshingly targeted on the Cybersecurity impacts, which are valid for the everyday person, already.
TL;DR - Quantum computing is great, if you're the bad guy. For the rest of us, there's a cost/value tradeoff in defending against quantum computing threats. People will tell us it's too much hassle to upgrade our encryption, but it can be done with reasonable effort.
Bruce Schneier has been saying for something like 25 years that technological advances always favor attackers over defenders.
Well yeah, that's why red teaming is so much fun.
And a big point is, it is a technology that we have to develop anyway, since big targets like governments, military or big financial or economic companies would want to defend against anyway.
