I understand the desire to trace one's family history, find/treat diseases, discover murderers, etc. However, any time I read about these types of personal information breach events (DNA and genealogy could arguably be the most personal info of all) I so badly wish we didn't have this tech to begin with and how much present day sucks compared to the past as a direct result of these personal data mining tech companies (thinking social media, surveillance as well). I also wish the general population thought more clearly about the long term consequences of their information being in the hands of others before they so naively and/or willingly divulge it. Worse yet, we often don't have the choice. Nightmare scenarios where some could wield such information to do harm are not too difficult to think up, and if we are really being honest with ourselves, are occurring present day. Personal information data playgrounds like Facebook become precision tools for deception and oppression at best, genocide at the worst (thinking Myanmar). Not to single out Facebook, imagine what a psychopathic genocidal leader could do with 23andme data. With the rampant data collection, the human population has never faced this scale and breadth of societal threat before and we are indirectly feeling the consequences of it in our lives daily. I wish we could go back.
