Just because the benefits of sharing DNA data appear large, doesn't mean we should take potential drawbacks lightly. Imagine this: a future where a specific gene is linked to hard work. Companies start screening job applicants based purely on their genetic makeup -- if you don't have the gene, you don't get the job. Or even more worryingly, imagine the government starts surveillance on a group of people with a particular gene, claiming they're more likely to commit a certain crime based on some obscure study. It would lead to moral and ethical havoc. DNA data might not seem worth protecting right now, but unchecked, the misuse could be catastrophic.
