What kind of questions is this? It will be sold to the highest bidder to cover debts of 23andMe

Who it's transferred to is a subset of "what happens". That transfer includes legally binding agreements. How those are respected, and the consent involved for those changing, is more on the "what happens" side.

It goes to the highest bidder. This is whomever can extract the most value from it, likely because they are the least constrained by the paltry genetic privacy laws we do have. This means it is likely to go to Muskov to use in support of his project to cleanse the surplus population, just as how he has already been employing the much more expensive Twitter.

The main thing I've got to say to the "nothing to hide" folks is "very slowly, then all at once".

I laid out a chain of easily-verifiable facts and straightforward heuristics to describe one likely outcome. It's not set in stone of course - insurance companies could end up seeing more value in the data for purposes of price discrimination. Or is my prediction so spot on you think I must be a time traveler that knows exactly what happened?

Not gonna happen, but man it'd be great to see a non-profit swoop in, buy the data and destroy it all (after giving the users a chance to backup their own personal copy of the data).
