Yeah, for a sophisticated developer with technical background, maybe the idea of setting up a messaging app that lets you talk to a home server is not a crazy thing. But this is for the most part a lot of normies realizing that that's possible and that you don't have to be highly technical in order to achieve it. And opening the door to doing anything computable interfaced via WhatsApp audio messages.

If you cant see why that captures the imagination of people, you should look at the world with more wander. Heck try reading poetry.
