Nope. Not for everything. Perhaps every phone conversation, but I don't necessary use my smart phone for talking. If I, for example, work in 1Password which encrypts the data while synching, the NSA can listen in on that conversation and presuming they haven't broken my password or the companies algorithms, that conversation is not understandable.

If it goes into the modem encrypted, having the keys to the modem isn't going to help all that much.

And you're an idiot if you're doing anything remotely illegal on a cell phone system anyway.

I'm sorry, this is not the 3D printer you are looking for.

No tissues or organs, no little machines. Nothing earth shattering.

Think Dungeons and Dragons pieces, Star Wars figurines. An occasional spoon. All looking like a low res poly rendering from the 1980's.

It's a toy.

As long as Milla Jovovich comes crashing through my roof, you can send me as many tickets as you like.

Go facepalm yourself.

Oh there you go again. More Mr. Fusions.....

Come on back with your utopian schemes after you work out the messy little details.

Water source? Power source? Financial basis? I take it that you are bankrolling all of these poor folk from Sub Saharan Africa and / or India to move en masse to Peoria?

Why would you even want to do that?

I can tell you why you don't want to - 'Most of Canada', 'Australia's Outback', Siberia, the Amazon (which you didn't mention) and the Tibetan Plateau (among other regions) serve as enormous ecological buffers. What do you think filters out all of the crap we're putting into it?

We've done oh so well on the parts of the planet that do have significant human population densities. How do you think spreading this out over the rest of the world is going to work?

And you're utopian statement of 'by 2100 even and individual could convert surroundings to their own tastes' is decidedly Star-Trekian. This individual and a Mr. Fusion, perhaps. This individual and a bunch of solar panels, not so much. Not such a bright idea to plan on rearranging the world using technologies that haven't been invented yet. Reality sucks sometimes, but it's reality.

And you forgot all about 'ol Murphy.

There already is a master key, or, more specifically, a master wrench. Preferably a 1 inch or larger spanner wrench.

Applied to various parts of the body it will do a wonderful job of improving certain specific memories. This isn't designed to prevent the NSA from going after you should they find that desirable (don't kid yourself, twinky). This is designed to protect yourself against two bit private investigators, your local sheriff, the creep down the block and your mother. No security is perfect, but this is lots better default security than most people ever get. Yes, Ms. Random Luser can defeat it by posting their passkey on Facebook or telling their soon to be ex boyfriend, but since security is a process, not a thing, nothing is always completely secure. And especially nothing that is designed to connect to the Internet.

-- Complex passcodes take more computational power to crack.
-- More computational power takes more electricity.
-- More electrical use leads to burning more coal and oil which leads to global warming.
-- Global warming is bad.

Q.E.D - complex passcodes are bad.

A couple of thoughts:

The researchers did show some suggestive evidence that gut microflora impacts glucose metabolism and that use of artificial sweetners can disrupt that. The numbers are low and it's not clear how germaine the results are too humans (poor mice...).

However, consider this: The microbiota changes only occur in mice fed ONLY the artificial sweetener. The thesis being that this clogs up some unknown regulatory pathway in the microbiota which leads to glucose intolerance. Although the did perform some mix-back experiments (n=7), they did not perform the standard 'rescue' experiment which, for humans anyway, would be very telling:

What happens with a Diet Coke and a Snicker's Bar? It's always best to test these ideas under real world conditions.

Inquiring minds want to know.

He really needs to cut out the bath salts. That's nasty stuff - you can tell.

Not at all. That's because we don't have teams dedicated to study tropical diseases or virology or epidemics or anything like that ....

Nope. Go read this fine article.

It is quite a bit more complex.

Please do do not move.

Place your hands on the monitor.

The SWAT team will be at your door shortly.

Turns out that "War" is a bad descriptor. How about "Global Viral Change"?
