To be fair, the parent did specify scaling "out" and went on to claim other benefits of a distributed architecture, which are not even unique to that architecture [1]. Of course, that comment's definition of "single machine" ignores the intrinsically distributed nature of mainframe architectures, on which on might reasonably suppose COBOL would run. [1] e.g. a "single machine" only needs a single replica for those benefits. Sure, even that's a form of distributed architecture, potentially subject to at least some of the Fallacies Of Distributed Computing, but I'm confident that's not what was meant.
