I guess but if a shadowy company wanted my DNA they could get it easily enough even if I don’t hand it over to them so I’m not sure how much point there is in being protective of it. Anyway what are they going to do with it, that a medical company couldn’t do?
The government already has my blood from back when they were doing medical testing, so it’s all a bit of a moot point anyway. Also an insurance companies took some blood and they did an MRI scan so they have my brain as well. Jokes on them if they choose to clone me, I’m bloody useless.
I don’t think it’s going to get much more broadly used than it is now. I work in cyber security and there have been password hacks like this since practically the beginning of the internet. It’s called a rainbow table attack, It mostly relies on the victims being complete idiots.
You don’t even need to have a particularly secure password to be safe from it, you just have to have a unique one from site to site. Even if in other respects it’s relatively weak it will still defeat a rainbow table attack.
The point is this stuff has been going on for decades and people are still making basic fundamental errors, so I can’t see how that’s going to change in the future. Maybe we should require everyone to take some sort of basic proficiency test before they’re allowed online.
