I do wish some more details about his current thoughts on actors had been included, though I can understand if they were hard to tease out. I would guess that may go back to his work on Electric Communities as E was a message passing system. Would be interested in hearing more of where his mind is on actors today.
The closest thing we have right now I think is Spritely Goblins, though that is Scheme. (Not coincidentally, one of the other Electric Communities co-founders is also a Spritely Institute co-founder: https://spritely.institute/about/)
