On the one hand, Jerrek's been a robot for a very long time, possibly centuries. On the other hand, he doesn't seem to remember much of that for some reason (my current guess is that it simply wasn't very memorable, just checking on some pipes every day, not much social interaction even with other robots). The fact is, he is like a person who's been around for a while when suddenly his body is reacting differently to everything and he's overwhelmed. This is like adolescence.
Re-read all of She Gave Us An Ocean to understand why robots are "mentally underdevelopped". Basically, to use the metaphor of that chapter, all their lives they've been living in a bucket of water, while the whole of human experience is an ocean of memories, interactions, feelings, sensations. It's a beautiful chapter :-)
A new person may very well be mature enough to handle the "horrible strain" of talking to a human they like, in their previous life as robots they already did talking to humans for years and occasionally liking them.
Jerrek can't even remember what his work was in his previous life.

- Kat is neither blind for Etheric beings/phenomenons, nor does she see all of them in boring simplified versions. All she does is see through Etheric "smoke and mirrors". - If(!) Coyote's Great Secret is true, then you can't change anything the moment you make some people believe in it. Humans have to die for their stories and beliefs to influence the Ether.
