Will insights in DNA affect privacy?

During a panel discussion on the congress of 'The commonwealth club of California' about Genetics co-founder of 23andMe Linda Avey and Mark Gerstein (Professor Biomedical Informatics, Computer Science, Yale University) and David Magnus (Associate Professor Stanford University School of Medicine) give their opinion about personal DNA and privacy. Because of the technological developments the off-line dialogue makes a shift towards the online world. But a lot of people forget that this also means that a lot of privacy sensitive information is stored online. Do you want that? Web 2.0 developments make that people even more information (sometimes personal information) share with each other. More and more people even share their health issues with each other online.

So with all those people share personal information via Web 2.0 tools with each other what will happen when people have actual insights in their DNA and their possible medical future? Will this transform the way we look at privacy and what we decide is privacy?According to those in the panel we have to review and re-define the word privacy.

From earlier postings here on Extend Limits I know that the subject privacy is very sensitive for many readers. And of course privacy is a hot topic and it will become even more with the rise of new technologies. But especially the younger generation seems not to worry about their privacy and give a lot of information on-line. What do think of this. When people have their insights in their DNA. Will this affect privacy? And do people need to be warned about the dangers of online share of information?

I believe that you have to be careful about what you say on-line because it is accessible for everyone. But maybe I am also a bit old-fashioned.
