This is about communication, so yes, you are forced to use something that the other side also uses. Because communication involves at least two people.

Sure, the UNIX nerd from 1980 can sit alone with his box and hack away, so all is fine. Typical slashdot reaction.

Too bad a single setup of meta material typically only works for a very specific wavelength.
So, it could be helpful with applications using a defined wavelength (for example soundproofing an array of many ultrasonic transcievers from each other to reduce interference), but it won't mask you from a wide array of sounds.

They used a camera.

I always thought this was a very bad idea.

Sure, it may protect him from those who do not want the information released.

But for those wo do want it released, they might feel motivated to force it...

Oh yeah?
I pronounce howling and rolling the same!
Your move.

You are joking, but that is pretty much what I'd expect from a working voice command interface (minus the misunderstandings!):
To be able to make conversation about the narrow field of $device_purpose.

So yes, a voice operated radio should be able to tell me what radio station I am listening to.
And it should understand common keywords that have to do with music, news, sound and such things.

If the system needs clarification and this requires the driver to inspect the screen, isn't that a problem with the implementation?

Clarification should be requested and should be given in voice alone.

Anything else defeats the purpose of the voice interface, doesn't it?

Hey, my first project with a microprocessor was also to make an LED blink.
This guy is off to a good start!

This is not true.

You will get a better stopping distance from rolling off the tires very close to the limit to sliding (in static friction) than from blocking the wheels and sliding to halt (sliding friction).
They will produce much more grip that way. Once they start sliding, you lose a lot of that.

Depends.
Was the tested subject time machines, or temporal magics?

They went and collected a random sample of clamps out of the million(billion) clamps down there, and one out of their sample happened to be over 500 years old.

How do you see the chance that they randomly picked the oldest clamp on the planet?

By the laws of large numbers there are a lot of clamps still down there, that are older than this one.
So rest asured, the oldest animal on the planet was not killed (I would have said 'is still alive' but that's circular logic).

For starters, no picoturtles.

I believe it is intended that you came up with those associations yourself,.
So when presented with the list of your past answers and the same group of pictures, you will be able to do it again.
Trying to reverse another persons association-list will be much harder (and that is kind of the point here i guess).

Today's Google opener is Hermann Rorschach.
Is this story just a coincidence?

I wonder what he could have read out of peoples passwords?
Your account may be secure, but now the admin knows everything about your mother issues.

You are listing applications.
Of course, once these applications are on the horizon, the money starts flowing.
But without basic research, that would never have happened. They would instead have funnelled the money into developing better tubes.
