all dna is interconnected as all humans are sourced from the same source dna. at some point, we will have enough dna in a database to be able to pinpoint almost any sample to anyone or their family closest in that dataset. it will eventually just be everyone. the set doesnt change, it will just grow as more people are added and its ‘accidentally’ released. its inevitable.

retrieving any humans dna you really want is fairly trivial. we need only minute traces anymore, and it gets less as amplification techniques improve. they already have molecular sniffing devices in all major airports. not for dna, but you get the idea.

ha, yes when you breathe you exhale a lot of particulate into the air, and guess what, its laden with your dna.

personally, i could not care less. have my dna, do what you will with it. oh noooes you have all of the numbers of me… whateverwillido?!

realistically, its only valuable in aggregate.

the only real concern ive ever heard was corporations making decisions on peoples dna, and that can be trivially circumvented by extending discrimination laws.
