How much description would the AI need to produce to get across the intended concept/object/idea?

Google for the very first image of something as simple as a spoon and try describing it in enough detail that is could be recreated in an image that is unlike all the other images of spoons. You'd probably end up with more data than simply sending the image as an uncompressed bitmap.

There are certainly plenty of "repeat" characters in different contexts.
For example the math alphanumerics: http://unicode.org/charts/PDF/...

At a point likely atleast several centuries (if not millenia) in the future.

The only think a government has to fear, is dissent within it's military ranks.
There are few coup attempts by non-military groups and even less succesful attempts.

The US constitution was written in a time where both citizens and government had access to roughly the same level of weaponry.
There were no tanks, bombers or drones, there was no fast communication or transportation of armed forces.

If one were to draft a new constitution in this day and age, you would look a bit silly for arguing a civil militia with handguns and old military surplus equipment could keep a well-armed government in check.

Seems to work just fine.
Now we just need a device that lets us control our minds.

Because checksums can't possibly ever be hacked!

So basically the same effect as taking a dozen XTC pills...

... with pretty much the same result.

Sounds healthy to me.

You know how old-media companies always go on about how copying media is somehow "theft", even though we all know it's not?
Well, the problem with digital authentication keys is similar; it can get copied without you losing anything.
Attaching authentication to a physical item that actually CAN get stolen changes the game dramatically.
It's a single point of failure that will give a false sense of security.

Even for analog cables, there were plenty far cheaper cable brands that offer the same or better measurable quality.

To me, they're all just a bunch of $500 wooden volume knobs.

Hmmm, that's an interresting point of view, european court.
Do you have a website where I may comment on this?

Why are you posting as AC if you have true freedom of speech?

So now that the government is making life a little less secure, does that mean we also get back some liberty?

If Russia and/or China would have decrypted messages, they would most certainly not tell the rest of the world.
Similarly, they wouldn't publish it if they managed to locate enemy spies.
If somehow, this DID happen, the US government would most certainly not publish the fact that they knew.

Information is valuable.
Information the enemy thinks you don't have is invaluable.

The fact that this is published tells me it's most likely not true.
