What are some of the differences? Besides the glaringly obvious text vs audio. I mean prior to telegraphs if I got a letter from my sweet heart with a lock of hair or something and a request for funds I’d probably believe it, especially if it took days or weeks to communicate back and forth?
Impersonating a letter is similar to having an impressionist record an impersonation of someone's voice. It's difficult, very imperfect, and not very scalable.
The analogy for this technology would be a robot that can perfectly imitate someone's handwriting and vocabulary using one letter as a reference.
