If it's not an issue for you, good for you. But then why do you care so much to tell others it's not an issue just because you can't see it?
I'm sharing the international perspective. Like I said, it only really matters to people in the US, not much of an issue for the rest of the world. People have iPhones outside of the US and still use third party apps to chat away, life goes on.
It's really funny hearing you be dismissive of these issues yet ignoring there are at least 3 organizations working on interop, and lots of people signing up to use them.
Dismissive of what? All I talked about was SMS support, I didn't mention anything about Interop, which I think is a great thing by the way, thank you very much for asking.
As I see it, why are you using garbage like WhatsApp or FB junk?
Again, what? You are setting up a straw man. Signal is my actual daily driver and I fortunately have been able to convert most family over. Of course, I still have to juggle multiple apps to talk to everyone else. But I'm not losing any sleep over it, and personally I think neither should you.
Obviously I can't speak to Bing's claim on GPT4, but the behavior you saw does not necessarily have to do with the model. There are many ways the "chatbots" on the same model could behave differently, either by defining those behaviors programmatically or via context and prompts.
