As someone who has had the experience of Apple Watch catching a heart issue (that unless it had I might not be here writing this) and underwent a battery of testing prior to two major surgeries, I can say with total certainty that Kiani is just throwing shade. I’ve had my Ultra on for every blood-ox test and compared my watch’s results against the “medical grade” testing equipment. The watch was SPOT ON.
Never once was it more than 1% off of the “official” results.
I do feel for the guy. As our consumer tech gets better and better even high end medical gadgets will, are, getting sherlocked. But seriously: don't poke the bear. 

No need for a “killer app”.
My current display doesn’t need a use case beyond provide a way for me to see information I can interact with. I just want it to display data appropriately. Deliver the user interface. 
I’m not sure why this device is so confounding. It’s just a really cool display. One that will allow creative people to develop unique experiences but it’s still just a display. Frankly, being able to work with files in a “Minority Report” esque 3D space is enough for me. But then again, I don’t struggle with screen time issues. I look at a screen until I don’t. I don’t live by my phone, tablet or watch. I just use them and put them down. This $3,500 monitor will be the same: play a game, watch a movie, shop etc. Perhaps I’m in the wrong community to state something I see as obvious but all these toys are just distractions that should only take up a few hours of anyone’s day. If one can pay $3,500 for something that has the sole utility of being “fun”, then enjoy it. I have no problem paying that much for a bike, kayak or whatever. Those are fairly limited in terms of “killer” features. However, as game consoles get more expensive (yet nothing near what this thing will cost) I recoil. No way I’m paying over $500 for a box so I can then pay $100 per AAA games plus a never ending monthly sub just to use the core features. I guess my point here is: it’s all relative.
CPG costs in relation to real income is absurdly out of control as it is. I highly doubt many “average” consumers will shell out $3,500 just like I won’t pay $2k for Studio Display with nano-textured glass.
But to assume this tech won’t shrink down to eyeglasses or even contact lenses and at that point as many people as have adopted the pocket computers we call iPhone won’t onboard is just nearsighted.
It may well bring a dystopia for some and utopia for others but unless we wipe our species off the planet, this UX will become dominant within a decade. Maybe by then the “killer app” will have revealed itself. 

“Requests aren't logged and user data isn't saved”.

My question and I suppose the deal breaker for would be: Are all interactions with ChatGPT used to “train” it? Because train clearly means consume and to an extent own. So it makes it hard to feel comfortable using it for anything professional. Many companies forbid using any LLM based services out of reasonable fear of company/client secrets being slurped up.
I really don’t see how Apple can honor their commitment to end-user privacy while baking in OpenAI’s little snitch at a system level.
I’m as concerned about OpenAI getting the data period, let alone it being attached to my identity.

I don’t really see what the big deal is with two devices. I don’t take my iPad outside my home unless I’m traveling and I certainly wouldn’t use a full blown VR headset in public either. However, outside the home I’m rarely without my iPhone and only without my watch if I somehow forget it. Similarly, I don’t take my Beats Studio headphones outside my home but always have my AirPods. Apple’s devices fit specific use cases and (as long as I have total control over privacy, ads, displayed content etc) I can’t wait for an Apple Glass AR/HUD device for “everyday” use and an immersive dedicated VR device. I’ll take both. I want both. I’m pretty sure that if done right, Glass will have an even quicker and more ubiquitous adoption than iPhone did.
