Communication seems to be a major selling point of the pin going by the demo, but I'm pretty certain it is impossible for it to work with iMessage, WhatsApp etc. in the way that is shown, so I'm wary about the actual advantages.
100% this, the lack of a clear 3rd party integration path does raise alarm bells in terms of breaking into mainstream as a customer product. Curious to see where they are going with their “we don’t do apps” LLM ecosystem.
