If you're gonna be paranoid about Gattaca you need to go all the way. DNA sequencing is going to be so cheap that it will be more cost-effective to sequence you

If you're gonna be paranoid about Gattaca you need to go all the way. DNA sequencing is going to be so cheap that it will be more cost-effective to sequence your ambient DNA from an elevator button or a used tissue than to look up your obsolete sequence data from some old 20th-century corporate database. The problem of misuse of DNA sequence information may be very real, but whether or not you do business with 23andme is probably an insignificant blip. We need legal safeguards, not minor-league personal boycotts.
