> I HOPE people aren’t spending money on AI writing emails.

They very definitely are. I'm seeing more and more front-line responses to customer support emails that are very clearly written by AI.

Here's an example from this week:

  Thank you for reaching out and providing all of those tracking and
  return details right away. I am currently checking in with our
  Returns Team to track down your package and see why there has been a
  delay in processing it since its delivery.

  As soon as I receive an update from our warehouse specialists, I
  will reach back out to you directly via this email thread with the
  status of your credit. Thank you so much for your patience in the
  meantime!
