We already have digital signatures. I don't see why not, as a next step, a world-wide acceptable form of digital identity should replace these more and more obsolete forms of identification.

We spend much more time online and we need to be able to assume our actions.

It is a fine line between assuming our actions and protecting our privacy, as you mentioned these details would need to be handled very carefully.

Thought-provoking post. Thank you, I resteemed.
