I perhaps differ from some other people, but I think the right to be forgotten would be useful. I think people would like the opportunity to extract their information. I don't know how technologically possible that is.
If I can use an example, if people are backing up on DVDs—not many people do it anymore—you can't extract one name from it. You'd have to rewrite the entire DVD, so it's impractical to remove one person's information from it.
The other thing is on where that information may reside in the organization. It may have been collected in one location and may be disseminated throughout the organization. It may be very difficult to identify all of the instances of that information and to be fully in compliance with the right to be forgotten.
In principle, it's a good idea, but there are some technological issues there.
