Page "Duncan Idaho" Paragraph 19

Assuming the responsibility of mediator between the two sides, and with Erasmus ' willing participation ( the robot being left as the leader and controlling-force of the thinking machines ), Duncan does something similar to Bene-Gesserit Sharing with the robot ; possibly along with what seems to be a physical-bonding ( similar to what Leto II did with the sandtrout ) into something of a human-machine hybrid.

Erasmus then voluntarily " dies ", while remaining an Other Memory speaking to Duncan.

In addition to being the Final Kwisatz Haderach of the humans, Duncan becomes the new evermind of the thinking machines, guiding their joint future.
