Ray Kurzweil is building a digital twin meant to carry his ideas beyond his lifetime

The replica is being trained on 11 of his books and a large number of hours of his recordings, with the aim of capturing how he thinks and communicates.

hours of recordings, with no exact figure reported

Training material, shown as units

Each block is one book. Recording hours are not quantified in the reporting, so they are not drawn to scale.

The stated aim

Capture his ideas and way of communicating
Let a version of him persist beyond his lifetime
Build on his own writing, voice and recordings

Open questions

Does it preserve anything meaningful, or only imitate him?
Is any form of subjective experience intended?
