I assumed OP either did a typo or wasn't a native English speaker

I have not encountered anyone referring to geographical Europe as "EU" before, that would be confusing!

EU vs US population

EU ~450 million, US ~350 million

I used to do it that way too, but my wife is not technically inclined, so we settled on something with a web UI for editing.
There are a few areas where the wiki is marginally better for me, the main one being the ability to do quick edits from a smartphone.
I do really like the simple approach with a static site builder though

Your own wiki, and your own social media-type service

I post miscellaneous notes to my social media-type service, and save lists and more organised information (including recipes) to my wiki.

The brain cells presumably have a life span... if this technology ever gets used in consumer devices, I'd like to know how people will try and squeeze extra life out of a failing component.
Take it out and warm it in their hands like an alkaline battery?
Give it a shake?
Sing to it?
Some kind of stimulant drug?

unsupported hardware, firmware bugs

I imagined something like this (youtube video L7iROzIKm1M ) but idk if it's still a thing

It's moot for me anyway because there's no chance of appliance makers opening up their hardware

EDIT: can't post a link to YT for some reason

As someone who's into home automation:

1. Some of the features are cool, like seeing what's in your fridge remotely. That'd be nice to have while I'm out shopping
2. I currently have an old NUC hooked up to a little interface and some speakers in my kitchen. It's a bit janky, and it would be nice to run that through some hardware that's actually intended for kitchen use

Admittedly I'm not sure I could justify the price for "would be nice" features like that

I'd love a fridge with network connectivity and 'smart' features, but I'd need control over the firmware it runs

Students who think they are chatting privately among friends often do not realize they are under constant surveillance

This is the problem
