I think Apple is hitting a wall that most tech companies are hitting. New gadgets aren't really improving our lives.
We have the internet on our phones, Now the internet is a wasteland.
Probably the biggest cultural innovation of the last 5 years has been podcasts and that's just gussied up radio.
Right, in your average 2020s home or office, "Ethernet" is almost certainly 8P8C (commonly known as RJ-45). In decades past it was more ambiguous – in the 1990s, coax – ThinNet/10Base2 – was still reasonably common; even the older ThickNet/10Base5 would still occasionally be encountered. So to some extent, being specific is a bit of an "old timer" trait–a habit picked up decades ago when it was still important, now maintained when it is rarely still necessary.
But even in the 2020s – in a factory, it could easily be M12 instead. Or even a mix of both – 8P8C in the offices, but M12 on the factory floor.
Honestly, even in a home environment, I hate how fragile and easily unplugged 8P8C connectors are (the worst part is when they get slightly pulled out, so they still look like they are plugged in, but the connection is dead or flaky). I've thought about using M12 at home before, but it probably wouldn't be very practical.
Interestingly DECT NR+ is a 5G standard on dedicated spectrum and has been designed to be a mesh from the start.
edit: it was Viasat not Iridium, I got them mixed up.
A good, fast reacting multimeter is likely better thing to get than a cheap scope.
That said the cheapies might be usable for debugging audio stuff.
