In practice, in order to use any Apple device (even for work) one needs to log in with an Apple account. It does not have to be "personal"

If you want, you can use the Apple apps on your phone and Apple account. If not, you can make an account for work only and get a "carry" phone. They also give you a Mac laptop - were you expecting a Lenovo with Windows when working at Apple?

... but it was a CA DMV app, not the Apple wallet. I've had it on my phone for months. Use case? In case I ever forget my wallet.

Why should we care how a particular application within a specific industry gets its energy? What is important is that everybody can have access to cheap energy, using ALL sources available (especially nuclear)

I like adaptive cruise control BUT only for long straight roads. I live on the mountains and using CC on hilly terrain is an exercise in frustration. It's simple control theory: the CC circuit does not have information on what is coming (change in slopes) so it can't pre-compensate, and it results in ringing around the preset speed. It's even worse when it's paired to an automatic tranny that needs to shift AFTER it has detected a change in engine load, unlike a driver with a manual transmission will do.

...I use google photo on iphone and every picture taken get automatically updated to the google cloud.

Should all motorcycles be self-driving too? Also, a corollary - will we ever see self-driving vehicles with a manual transmission?

There is not such thing as surgical steel. Sometimes 316L is called that name. However it's a terrible alloy for toolmaking.

WD-40 is not penetrating oil. Sometimes it works but its performance for this application is low.

I lived in Italy, Germany, US, and used each of their healthcare system. No, I didn't visit those countries as an exchange student, I worked and lived there for decades in each. Conscious of its imperfections, I'd still choose the US system (Kaiser in particular, so insurance and provider are one, no paperwork to care about). There is nothing about "socialism" in my preference, just experience for me and my family.

Kids can fly unaccompanied on most airlines from the age of 5. It does not mean, and that is where you are wrong, that they are fully independent, there is a grey zone where remote telemetry can be used to mitigate risks and augment situational awareness. Having introduced them early to unaccompanied international flight, they will be ready to travel completely unsupervised (no airtags or tracking devices) earlier than individuals that never experienced that.

You are severely out of place. If you read the thread, I was replying to somebody that was asking for airtags to be difficult to use in public places, events (for what reason, I am not sure, it would accomplish exactly nothing in the fight against the stalkers). Of course my kids want to share their position with us, the airtags are not hidden.

Of course my son shares his location with google maps. But cell-phones are less reliable than an airtag as they need a working internet connection in random countries (and drain batteries faster etc). Also an airtag goes in the backpack and that can be tracked independently in case it gets misplaced.

They are supervised by the accompanying crew, that is mandatory up to the age of 12, and when they arrive by the professionals (including alpine guides and other instructors) that are taking them to the activities we planned. Airtags gives us situational awareness on the progress of their journey and, as I said in an earlier comment, would allow us to react early in non-nominal cases. They know very well how to behave while traveling, what does it matter? What if the airline has a problem and they have to spend a night in a hotel in a random country? Knowing where they are we can easily phone the location in order to establish communication and plan follow-up actions. Of course my son has a cell-phone, and he actively shares his position with us through google maps, but that requires an active internet connection, not always automatically available in layover countries. (He even has a Part97 license in order to stay in touch in areas outside cell-phone reception, and can enable APRS on his radio when he goes exploring while we are camping, but that has limited impact in the international travel use-case) I truly do not understand why you take time to write a comment and then throw in insults like insinuating I am a tiktok user. On the other hand you sound like a decent parent, and if you had any context, I am pretty sure you would want to send your own kids along with mine.

What do you mean airtag won't do a lot of good across multiple jurisdictions? The good thing about the airtag is that one does not need an European SIM or logging in in some captive portal, it just works all over the world. "Do my job as a parent [...] being present". I cannot even be mad at this comment, in fact it makes me laugh because if you had any context you'd be wanting to send your kids along with mine (several other parents we know want to do that next summer). About the very unnecessary comment about the corpse of my children (you should be ashamed for having said something like that): what an airtag gives me is situational awareness. In case they get separated at the connecting airport overseas, we can alert the accompanying crew, or in general be aware of the location while in transit. Should something be not nominal, we can react early. Additionally, the airtag in their backpack can be used to locate it in case they misplace it.
