Thanks Joseph
Trouble is there is stew of technologies/languages…
(meta)-stewed with more abstract concepts, eg push vs pull, Enumerable-Observable
duality, continuous vs discrete time
The last causing its own share of confusion with “functional reactive programming” (FRP) meaning sometimes the one and sometimes the other:

As for 'Overlook the “async/await can be used without significant buy-in” '
I believe Ive seen people with considerable experience/understanding of the area
take the opposite view, usually along the lines: “Once you start going non-blocking,
you have to non-block all the way”
