They should not be worried, they should be educated.

If you worry a new user enough they’ll go back to Windows or Apple because there’s less scary warnings there.

We need to make the transition as pain free as possible. Learning about the joys of kernel compilation and SELinux can come later.
The first step is "Hey, this is as usable as Windows, without stupid ads in the start menu.

Sounds quite similar to Markov chains which made me think of this story:

Still gets a snort out of me every time Markov chains are mentioned.

IF you already have an email domain you control.

Calling “acquiring and setting up an email domain and configuring the mail server for wildcards” “basically no extra effort” is a bit disingenuous compared to “solve a captcha for a Gmail account”

Yeah, inductive charging is basically a must.

Especially because it eliminates the guesswork if the watch is correctly seated to charge

No actual technical solution here, but it smells slightly of XY-Problems.

From what you described it seems the main issues are

• too many calls
• not knowing who’s calling
• not wanting to answer the phone
• not reaching the phone in time

Maybe you could look into solutions like setting a custom ringtone for important callers or having the phone announce caller names so your mother can decide if she wants to make the effort to get her phone.

I’m speculating a bit here but I can imagine that getting up and answering the phone is exhausting for your mother. Also if her mindset is " a ringing phone means it’s important" that could make it even more stressful.

Maybe you could find a way to let her silence all calls except caregivers and ICE contacts. (On Android DND exceptions could work for that)

That way she doesn’t feel pressured to answer the phone every time it rings and stays reachable.

If it’s actually just the physical issue of reaching the phone in time, does she have a convenient way to carry the phone indoors like a lanyard?

Hope some of this helps you

Ah, you “work” in “marketing”?

Very neat idea, but I’d explicitly add strong encryption to that method, cars do get broken into.

I’d encrypt every off-site backup, but a car is a bit more exposed than a rented safe box.
