There is always some complaint that we’re loosing historic documentation (people write less letters, whatever): as usual, the technology of creating and publishing content is only growing the raw material needed to for reportage. In fact, it’s so much raw material as to be overwhelming misunderstood, and ignored by those who only know the old tools.

Also:

Some are so stunned by the connection that they don’t really know what to do about it and mostly hang back: previously hidden injustice, factotum, and rebels.

And, that trove of images and videos means facial recognition can be used.
