Sure, that's the gap that needs to be filled. In the age of deep fakes even more urgently than before.
But which work cultures will find it easier to effectively deploy countermeasures?
Informal ones, where everybody acts like first names buddies all the way to the CEO, where they believe they are invulnerable because all those pretend-equal underlings are invited to speak up when they sense something fishy? What if they don't sense anything?
Or formal environments, where authentication tools could be systematically added to the preexisting and deeply entrenched set of rituals?
"That guy is not just acting like a colonel, the device we now all have to hold while saluting confirms that the biometric checksum embedded in his uniform insignia matches and is signed with central command keys". Yes, that protocol is not in place, but if it was introduced it would actually work. Now try the same in an informal environment where everything is supposed to be solved through good personal relations. The exact same tools, deployed in a buddy-org, would only ever get used retroactively, for pushing blame down the hierarchy.
