This seems like the first instance of deep fakes fooling politicians on a geopolitical scale. The repercussions of this are huge.

I really wonder how big the impact of this technology is going to be, especially since corona has made online meetings even more prevalent.

Cryptography (public key signatures) can mitigate this, alongside a globally public, decentralised identity system.

I predict that in 2030, we'll all be using digital signatures as part of our identity, whether directly or indirectly.

Are there any examples of decentralized things running at such scale? Whether in the digital world or physical?

Good point on the cryptography. My passport already contains such a key, so it is probably feasible to use something like this for trusted communications.

Until you reach the level of authorities that provide those signatures.

I'd imagine fake IDs with properly signed cryptographic keys on their chips are available to any higher FBI, FSB or other agents.

For their respective nations and ones considered friendly - likely.

For more foreign nations? Given proper PKI, I'd hope not.

My dads second wife has five passports. And more than a few names.

Whereas my single passport is expired mostly because I dont plan to go anywhere.

Names and identity are different.

In particular names only need to be locally meaningful.

Zoom (or Teams or ...) will allow you to change your face as a feature.
