Workers are network addressible which seems to directly respond to one of the complaints in the article. Beautifully, if you call one Worker from another they have a decent chance of running on not just the same server, but in the same process. When one Worker calls another its data doesn't even leave user-space, even if the two Workers are owned by different people. Imagine calling a third-party API and having your request never even need to leave the process to be handled.
