Going forward, it will be a requirement of genuine, worthwhile conversations that they be had between somehow provable human beings. Digital IDs are central to this of course.

Respect for human dignity is the key.
If this actually could be solved via free Internet tools, it would be worth a Nobel Prize (or the like).
