Async Ruby is rapidly maturing. I haven’t run Falcon in production yet but it’s not difficult at this point to setup Rails to take advantage of async IO.

  I find these attempts to bolt async onto languages like Ruby and Python a bit pointless as the ecosystem isn't built around async so gems don't work. If your community rallies around async as the default and library output is growing then just maybe but it will take many years to catch-up. Python could maybe pull this off as library output is accelerating but for Ruby, where library output is declining (see https://modulecounts.com https://modulecounts.com), it seems futile.

    The fiber scheduler solves this as concurrent execution is now built into the core of Ruby 3.

      Do you think it's perhaps confusing to call it async ruby? I was sure it works similar to node's async event loop but actually the fiber / fiber scheduler thing is more related to threads and doesn't use an event loop (?). It doesn't really matter I guess but the terminology "async" is kinda used in javascript land to mean event loop and afaik that's not what you're working on here right?
