Where these companies are scary, is if they sell personally identifiable information to insurers, or someone who can use the info to actually create rates based on your dna.
Or the other scary way in taking them, is in theory at some point an insurance company can ask if you have ever taken a dna test, and if yes, they could ask you to tell them about it, and then you can't lie.
pretty sure the above is currently illegal, but who knows in the future.
1. No, the FUD that insurance companies are going to discriminate against you is not going to happen. (At least in the USA) https://en.wikipedia.org/wiki/Genetic_Information_Nondiscrim...
2. Many of us, myself included, submitted data to them so they could hopefully make drugs. And I hope they can sell them at a profit.
Look back when I had family working with Eli Lilly we would take soil samples on vacation in various remote areas to send back to their research lab. This was pretty common as they were looking for new and unique antibiotics. You know what happens to a drug when no one can make a profit on it? No one makes it.
I hope that we come up with some novel an unique drugs that will help people around the world. I don't care for any form of payment or compensation, and I am happy my genetic code is one of many millions in the dataset.
I am really happy with the work 23 and me is doing and I hope more comes out of them.
I hope they use their genetic data to develop more drugs.
