You seem to be forgetting a lot of previous products. If anything these are a really late reply to Snap's Spectacles.
Also, these don't have a display. Many of your listed use cases don't apply unless you count audio replies, which we already have, all over the place. Please read about what a product does before correcting someone in the future...
I attend concerts a lot, and often post snippets to social media. There's always a tension I see among myself and others of trying to catch those particular lines of a song, while still not missing the show to mess with your phone.
Will I buy these? Meh, maybe. But the appeal is there.
I don't think so. Do people at a concert hold their phones out to be seen recording? No, they just want to record and that's the only way to do it. They'd love to be able to do it hands free for sure.
Sure, scuba divers still need some specialized gear, but there's tons of room in the sports segment for this kind of product.
I would not say any of those are compatible with wearing fashion-style sunglasses. I've lost pairs of glasses paddleboarding and kayaking before. I'm a mountain biker as well and crashes can be violent, I wouldn't trust glasses to stay on your face. All of those sports require firm attachment for a device worth more than say $100.
