Your original question was answered by numerous people in the spirit of the community, so you have got best answers it can provide at the moment, but your follow-up comments suggest that you don’t think so.
But I may have misjudged your intent, as looking further I can see you’ve been replying to comments individually. My initial impression was that you were masquerading statements as questions. If I have that wrong, then my apologies.
Have you seen the list of safety features on UK plugs and sockets? The sockets have shutters in them that prevents anything being inserted into the live or neutral sockets unless the (longer) earth pin of a matching plug is inserted first.
Having said that, I agree: seems to be a belt-and-braces approach. No downsides.
And it allows you to cut power to an appliance without having to remove the plug.
Safety and convenience versus the cost of including them, I expect.
The Wikipedia page for BS 1363 says they’re optional and weren’t added to the standard until 1967. I can’t recall having seen a domestic socket without one.
But it seems the only legal way to read the actual standard is to pay for it, and even the HSE website isn’t much help.
It’s a pretty common and wildly successful marketing strategy to put something on social media with one or more intentional errors to force everyone’s inner Reply Guy to fight the urge to do the thing.
But it also works with unintentional errors. My less well-thought-out replies attract responses like flies. 😄
Whether it indicates the success of your thesis or not depends on how you measure it, I suppose.
As others have said, it comes down to people not enforced on/off switches. You can’t (well you can, but should you) stop people living their lives.
I was out with 3 friends tonight (all middle aged), meeting first for coffee, moving elsewhere for dinner and drinks, and ending with tabletop games (the place we eat/drink is happy with it). One of our group couldn’t stop looking at his phone throughout the time we were together, and the rest of us didn’t pull our phones out of our pockets once. (None of us were on call, contacted by family, or anything like that).
Just as some people have their phone ping them for every notification (often loudly, every few minutes), some feel they can’t live without the dopamine hit of a meaningless social media interaction from a stranger. 🤷♂️
As much as I’d like it to be, it doesn’t have the network effect/popularity that Reddit does. It covers maybe 70-80% of my Digg+ needs, but there are many topics/subs I want that Lemmy just doesn’t have.
“Be the change you want to see” is always there: if a topic/sub doesn’t exist, you can always create it yourself. But no good deed goes unpunished, so you’re now the owner/moderator…
I asked this question many years ago on a Usenet group, and the answer was along the lines of what we’re seeing is many millions of years after those orbits began, and that they all eventually flatten out due to the gravity of the other objects in orbit.
So you could have 2 objects at roughly the same orbital distance but perpendicular to one another (eg. one orbiting the star’s poles and the other around it’s equator), and over time the small amount of gravitational force they exert on one another will bring them roughly into the same plane.
Hopefully someone better versed in the topic can come along to explain it better than I can.
This is what FAFO in public looks like. Gold!
