It is nice to see folks experimenting widely with unique visual representations of agent orchestration, as a consequence of the bottom-up / individual-led development that's driving the industry (inasmuch as it exists yet).

There are folks young enough now that they've never known anything other than "the desktop" (or CLI) as a computing metaphor.

But there's no fundamental reason a metaphor has to be anything specific... it should be whatever is most widely comprehensible and efficient for the problem space.
