In other contexts, someone I knew had written a system to generate automated emails in response to various online events. They later ran into someone who'd written automated processing systems to act on those emails. This made the original automater quite happy.
(Context crossed organisational / institutional boundaries, there was no explicit coordination between the two.)

How is AI in email a good thing?!
There's a cartoon going around where in the first frame, one character points to their screen and says to another: "AI turns this single bullet point list into a long email I can pretend I wrote".
And in the other frame, there are two different characters, one of them presumably the receiver of the email sent in the first frame, who says to their colleague: "AI makes a single bullet point out of this long email I can pretend I read".
The cartoon itself is the one posted above by PyWoody.
