This does a good job of encapsulating the considerations of an event driven system.

I think the author is a little too easily dismissive of sagas though - for starters, an event driven system is also still going to need to deal with compensating actions, its just going to result in a larger set of events that various systems potentially need to handle.

The virtue of a saga or some command driven orchestration approach is that the story of what happens when a user does X is plainly visible. The ability to dictate that upfront and figure it out easily later when diagnosing issues cannot be understated.
