Sorry my friend, but nobody here has the slightest idea how entanglement works, let alone quantum physics.

Well, I have a *slight* idea. Entanglement is a property of QM, which is a model. Mathematically we know exactly how it works. And it makes predictions that match observations. It's only confusing (very!) if you start asking what is happening under the hood with reality.

Nevertheless, the idea is that, traditionally, even the best encryption does not guarantee that the message hasn’t been intercepted. By using quantum entanglement, the recipient of the message is guaranteed that it has not been intercepted (or, conversely, that it has been).

You can get the same result by using a one-time pad. Anybody intercepting just sees random noise. And you can embed it in continuous random noise so they don't even know when you are communicating. QKD seems a whole lot more effort. Distributing a terabyte pad (say a TF card) is just as easy as distributing a single token for authentication.

... with a concrete example.
So you are talking to a remote person. All you need is a pre-shared key in order to exchange session keys.
If you don't have any pre-shared key, then how on earth can you authenticate? How do you know you are doing Quantum key distribution with the right person?
Surely it is only resistant to MitM attacks if you trust the endpoint. And by what method can you trust the authentication, which does not also provided easier session key exchange than Quantum Buzzwords?
    What is the purpose of the tech, aside from raising more funding for research?

"Numberplate Address Translation"

Most cars rarely leave their home town. So allocate number plates to each city. Then cities issue their own internal number plates, and any cars leaving the city just borrow a city-owned plate for the trip. The city keeps a registrar of which local plate corresponds to which state plate at any given time.

This of course is just a temporary measure, until the new national 16-letter number-plate system is launched. It will take a few years for everyone to update their forms to accommodate that.

Good point. Social media promotes outrage. But it isn't a new thing - as the old proverb says, “A lie can travel half way around the world while the truth is putting on its shoes.”.
    An example of an easy lie is people attributing this to mark Twain:-)

Did we make up that he's a 30+ time convicted felon?

This is not in debate.

There's no need to lie at all, because he's the liar-in-chief.... And you're saying we're the liars? lol.

Correct about trump. But not on the reasoning. You say "no need" as if this is evidence that it does not happen.
    I even made some bold for you. We lie even though there is no need. Also, our lies do not justify his. They are not equivalent. Ours are less consequential. Nobody is making excuses. Is that so hard to understand?

You're either not paying attention or

A-grade irony there!

you have some kind of twisted sanewashing agenda.

The insane part is in thinking that calling out one persons lies somehow is denying another person's lies. That is some very twisted logic. OK, you seem to be taking this personally, so let me make it simple:

    1) Trump says Haitians eat pet dogs.
    2) Alice is angry at this, reads somewhere that Trump eats babies, and re-tweets it.
    3) Bob says Alice is repeating a lie, and should check her facts.
    4) "leptons" screams that Trump is evil, Alice does not need to make up lies, and therefore Bob is a Trump-lover.

Which one of the above 4 sounds sane? Answer 3) . Just 3)

Nobody has to make up anything bad about trump, vance or musk - their actions are inherently bad.

And yet we do. All the time - it is human nature, sadly. When we hear the latest horrible thing "that arsehole" in the capital has said or done, we don't question it before repeating it.

If told a bad thing about a person we respect, we might check the facts. But that arse has said worse things before, so it must be true. The average internet denizen actually lies more often and more easily than Vance, because it has no consequences. It isn't reported as much. We don't think of it as lying, but selective repeating of wild allegations without fact-checking is exactly what they do (Haitians eating pet dogs, unfair trade by other nations, whatever)

The worse the person, the worse the lies about them. So be careful what you believe, and even more careful in what you repeat in public - if you want to be better than them.
