Like robocars killing people, it feels worse when it's AI.
I mean, before it was humans using template text with dynamic fields; in some cases the first time the sending human would actually see the message would be if you responded.
But now you can get all the way to the first call booking without a human ever being troubled to participate in the interaction.
In my experience, LLMs have not improved the quality of targeting (let's assume for each person doing outreach there are at least a few people who actually want the messages being sent), and my inbox is absolutely flooded with AI generated campaigns. I have stopped unsubscribing and I just mash the spam flag.
