We also already have dna collection through ancestry.com and the like which opens up intergenerational layers, for example, health info. An amazing book ‘The Invisible History of the Human Race’ by Christine Kenneally also talks about how owning the data also enables changing it. Just like every other tool humanity invents, it can be used for good or ill. I observe that those who are drawn to the procedural development of, for example dna collection banks, or data scraping, are typically so left hemisphere dominant in their thinking that they don’t/can’t imagine the breath and depth of potentiel risks, while simultaneously perceiving themselves to be more knowledgeable than anyone else. Iain McGilchrist does great work on this. So the task is not just to educate the normies to the risks of giving up data, but also to educate the clever developers/inventers to the potentiel risks their genius tools/weapons can be.
