The late great Joe Armstrong is missed! Good suggestion, I will take a look at Elixer/Erlang. It's the least I can do for the laughs Joe gave me in his videos.
Shameless plug if you like videos: I gave a talk about Erlang, building the language (focus on semantics, not syntax) up from the fact that the = sign doubles as a runtime assertion.
Joe was indeed a great guy. I was lucky enough to spend some private time with him when he was visiting Chicago to give a talk, a true renaissance man with wide-ranging interests.
Good talk! I didn't believe that Go example was real at first. A bit strange. I always think of Alan Kay's message passing objects when listening to descriptions of Erlang and tonight I also thought about Kubernetes pods. The other thought is one you touched on is that some systems are monolithic so you have to handle errors. Thanks, I enjoyed that.
