One of the more obscure things he pursued as a result of his early actor model work was unbounded nondeterminism as a potential source for hyper-computation.[1]
I'll always remember fondly that he pointed me to some papers via twitter when I asked him some questions about unbounded nondeterminism as an undergrad.

* thank you Jim Gray (1944-?2007). compare the difference in liveness provability between token ring and ethernet. (but also compare their pragmatic adoption)
I first heard about Hewitt after watching this[0] conversation about the actor model. It's truly a masterclass. For those who want to learn more about the actor model, or simply have a fond memory of ProfHewitt, I highly recommend it.
I've met him at Code Mesh in London in 2018 where he gave a keynote on ultraconcurrency for globally connected intelligent systems [1]
Joe Armstrong was present too, he had a talk later that day and I witnessed a conversation between Armstrong and prof. Hewitt about the actor model after the keynote, it was brilliant.
Unfortunately they're both gone now.

Probably deserves the black bar?
a fmt(1)-ish filter, or perhaps simply manually folded. In conjunction
with the formal clarity he often expresses, they develop
a poetic, almost dreamlike quality.
ps: j-pb above mentions planner, also linked to the logic programming world. damn
