All great until this was used for people control. Collecting dna which you cannot control and even can trace your race or relatives.

We have internet. Great. But look at the dark side. DNA is great like target medicine but you have totalitarian regime which might use it.

Need some sort of awareness. How to deal with the two sides, let us discuss once you know there is a very dark side to it.

Thanks for your concern. All technologies come with benefits and risks. Of course, DNA sequencing can be used for harmful purposes, eg. tracking individuals. We should be very cautious of these risks as the technology develops, and take well thought out steps to mitigate them. A similar analogy can be made to the internet and tracking people. Overall, however, the benefits of DNA sequencing to society already far outweigh these risks.
