The 23 and me stuff is expecially scary. It is bad enough giving out genetic information to a company. It is even worse when that information is stolen.

Anyone interested in using a gentic ancestry service should read the book Genethics by David Suzuki & Peter Knudtson first. TLDR if a big enough genetic data bank is aquired by the wrong hands, discriminatory practices could increase significantly in job interviews, health insurance and other sectors. Chemical warfare could also be specifically tuned to specific genetic groups.
