I'm glad to be switching last night's twitter discussion to a bigger
medium.  My question here is: what is the proposal (if there is any) to
balance these and simultaneously ensure that we don't wind up limiting
ourselves or providing really bad foot guns or two APIs depending on
whether you're in the main thread or a worker?

Blocking communication (cross-thread/process/computer) was a mistake. We
need a culture shift. The browser and Node.js are a step in the right
direction (they did not initiate it, but helped popularize it).
