If a state actor is trying to engineer a bio weapon to kill me specifically, I think there’s a number of ways they can get my DNA.
Though I don’t think they’d need to- I think if the CIA wants to kill me quietly they’re gonna bump into me on the sidewalk and use their own undetectable poison that isn’t specific to me.
Might make for a good movie, but otherwise just a bunch of malarkey.
There isn't a short set of DNA which marks each person uniquely. This sci-fi weapon needs to recognize a scattered set of changes in the DNA, then activate some sort of toxin? Or trigger a virus? Which must be enough to kill the person, but not affect anyone else.
So it's what, a bioweapon - with all the difficulties that entails - then a sort of sensor genetically added to the viral/bacterial genome so each cell can recognize just the right DNA, along with some sort of error correction system to prevent mutations in that sensor system.
And, you know what you could have if you could create genomically targeted bioweapons? A cure for cancer.
Worrying as they CCP may be linking the data they have on you from Chinese apps to the DNA address records. If they then find your activity online to be anti China or an unfriendly state actor in the future they know how to target you without anyone ever finding out who sent you that packet of chemical in the post.
