> In 20 years we will be able to extract all type of crazy information from DNA and it might be our biggest liability if it is shared across private companies. This will truly be the dystopian future, in which every business will make a decision based on your public DNA profile.
I really doubt this. I've been genotyped by 23andMe and the most interesting information I've seen from their health reports are a handful of disease probabilities and some fairly useless-to-me traits (like, for instance, a probabilistic view of my hair color). Even if you jump into the fray with something like Promethease or look at data on SNPedia, each SNP only has a handful of studies and there's little to no research on hundreds of thousands of SNPs. Only a few sets have been analyzed for specific purposes like Alzheimer's and rare diseases, and those are indeed rare.
Science doesn't advance like the technology industry. It takes slow, methodical research to point to anything super conclusive. If we wanted a dystopia where job aptitude was determined by DNA, for example, we would need hundreds of studies and conclusive evidence that some genetic data indicates a very good match and not just a hunch. That research has to come from somewhere, continually be reproduced, and undergo the scientific process. That's all stuff that has to be paid for, which is something not a lot of people are willing to do.
> why would ANYONE in their right mind give their DNA to a company in Silicon Valley that is explicitely using Google as a model for Data privacy ?
It's more of a curiosity thing. I get a more complete view of myself, and we potentially help advance research in medicine and diseases. It's symbiotic.
