If you type something into the computer you should assume everyone in the world will eventually be able to see it.
If you send your DNA to a company in the mail you should assume everyone in the world will eventually be able to see it.
So, what about healthcare? Back to paper records? Because it's not acceptable to me that everyone in the world will eventually see my private medical records.
It's probably too late for that to be honest.
You should also assume your MegaCorp, if you work for one, has also already seen them (in many cases they can buy them from various data brokers or even off the grey market).
I'm not saying this is the way things should be, just things as I know them to be.
What remedial steps would you support, out of interest?
For example, if someone could have their current life become, essentially "redacted", and receive an entirely new one with fairly low barrier of entry, would that be something you would support?
I do agree that once it's out, it's out and you can't really "go back" or have any expectation that what you put out there will somehow magically be "safe", but I think there ought to be a means to hard reset; a burn everything to the ground, and start from square one option.
To head off the inevitable questions of some variation of, "...but what about abuse?" from the croud, I would generally ask:
Abuse to whom? The person who's entire existence is irrevocably captured, documented, data mined, and optimized for malicous intent? Or the random mouth breath8ng schlub who abuses the opportunity to do something nefarious before getting caught and going to prison?
