I'm in the no camp for many of the reasons already stated. I guess I am just too much of a cynic to think the companies that get your DNA will do the right thing. I just prefer that mine stays with me. There are a lot of unintended consequences with technology and the speed at which we are embracing it; Artificial intelligence is coming sooner than most of us realize. I'm not saying I think our DNA can be used nefariously, but we don't really know that for sure do we?
