That's very sad. 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.
