The only truly universal solution
From schuko to shocko
I think Randal would enjoy my plug adapter
Ugh, what a shameless plug
You try spending your whole life getting penetrated by various foreign objects and not feeling shame
This also makes me wonder why the xkcd one was laid out like that. Is the xkcd one better/safer, or was it done that way to look more insane.
On yours, the Canada/US and UK layouts overlap, while in the xkcd one they're opposite to each other.
What about the voltages and the hz?
I'm not sure I fully get the joke, considering the literal existence of outlets like this. Did Randall not know they exist?
Randall isn't suggesting a universal wall plug, he's suggesting you cut holes in your existing plates to make them "compatible". (At least that's how it reads to me)
Plenty don't fit that. Type i for instance.
Can't speak for all of them, but type I does fit
Typical wall outlet in china. Any plug will hang loosely in there and work. Dangerously
Only if the socket is worn out and you are using a plug without inherent safety mechanisms.
As an engineer, thinking of designing the metal connectors needed for this, this gives me nightmares.
Simple, just use a metal mesh in each hole. Make sure it’s a really thin mesh too, like practically steel wool. Pushing 1500 watts through steel wool has never caused anyone any problems ever.

Good news, you can just buy them from China at pennies :D
I actually have a really annoying problem in that I cannot find any universal adapter that has a real ground pin.
All of them only have prongs for the hot and neutral wires, and sometimes a dummy plastic ground to grip the socket better.
I understand that 99% of the time, modern electronics don't need a ground cable and its only there for safety, but it would still be a lot more comforting knowing the ground is actually connected.
I even considered modifying an adapter with a ground cable I can manually insert into the socket.
Seems to be incompatible with some plugs, after all:
For some reason the image doesn't seem to work for me, so here's the link to it, too

Electricians hate this one weird trick
I have faith that we will eventually standardize plugs internationally. Assuming we avert the apocalypse, that is.
We can't agree which one is best. When Tom Scott proclaimed his home plug to be the best I scoffed. I thought my own home plug is better. But in reality I think they all suck in their own way, every single one of them.
I think a new more research driven approach like the USB-C design would be better, something that protects your fingers, is easier to locate when behind furniture or in the dark, works in more than a single position, is not going to stab you if you leave it on the floor, does not get stuck in the socket, I think it might even be possible to add a fuse without making it larger than a typical phone charger, but to be honest, the smaller the better. One can only dream.
Randall himself already solved this problem
For up to 480W of fun!
Now there are fifteen standards...
That's generally the thing with decisions that don't matter much. If one option is much better, there is no discussion.
But if the benefits of either option are marginal at best, you get tons of discussion and no decision.
For example, the EU decided almost a decade ago that they would get rid of daylight saving time, and everyone quickly agreed that DST sucks, mostly because changing the clocks sucks.
Since then, the whole EU has been arguing about whether to keep summer time or winter time, even though that matters so little that we have been using both of them for decades. A week after switching DST, nobody even notices the time shift.
That's why at work if a discussion goes on for too long I usually point out that that's the case because all options are almost equally as good and thus we should just pick a random one instead of continuing to waste time discussing in circles.
Don't know where all that research driven approach led us... USB-A worked perfectly, nobody ever had a problem with it; except having to turn it around a couple times to figure out how to plug it (which could be solved with a coloured dot on plug and cable). USB-C had the advantage of being a little bit smaller, but it sucks in any other aspect. While I might have broken a couple USB-A cables and plugs in my life, I do not expect an USB-C cable to last much longer than one year.
Usb-c has already proven itself to be reliable, it was designed to be reversible, it is easy to insert and remove with good tactile feedback and is compact while having lots of versatility. All traits I would love to see in an universal power plug.
To me USB-A was what schuko is today. It works and is mostly fine but I'm sure we could do better if we put our minds to it. The problem with todays plugs and sockets is they all work just about, enough that no one with any authority is going to bother with the topic. Any improvement needs to be by an unrealistically huge margin to be worth the investment required.
We can’t agree which one is best. When Tom Scott proclaimed his home plug to be the best I scoffed. I thought my own home plug is better.
The UK G type is the only one which is insulated, fused, grounded and polarized by default:
https://en.wikipedia.org/wiki/AC_power_plugs_and_sockets#Comparison_of_standard_types
This is great for electrical safety, though it's a very bulky plug.
Why the hell would I want the plugs to be polarized? Brits really stockholmed themselves into thinking that being unable to turn the plug around is a good feature. This is fine and dandy by Brits' standards.
Same country that convinced itself that you should have one hot and one cold tap, and if you want to get proper temperatured water just fill the basin.. instead of just combining them like the rest of the civilized world.
Mixer taps exist in the UK and are widely used.
Quite a lot of plugs are polarized, as you would see if you followed the link in my post. This includes plugs in the USA, Canada, Japan, China, Argentina, Switzerland, Denmark.
