And people don't usually die of "old age" but of things related to it. When the body gets older, the immune system gets weaker, your bones and muscles decay, your brain gets messed up, and a lot of deaths are in reality just a mix of a bunch of factors that just result in the body kind of shutting down. None of that will happen anymore.

And there's a feedback loop here too, because you a) have less life left to live and b) is generally weaker you get less treatment. A relative of mine is dying from cancer and it's low intensity life-prolonging treatment. If he was 20 years younger, they'd put him on high intensity drugs that would keep the cancer suppressed much, much longer. If he was 50 years younger, they'd probably try a full bone marrow transplant which is a massive procedure that is not only ridiculously expensive but likely to kill the old by itself. So being forever young wouldn't just avoid age-related diseases, it'd open up far stronger treatments as well.

Even if it worked (I doubt), this does not mean that you stay young forever. You don't age normally, but all your joints will be used up purely mechanically. Not ageing does not equate to 'no wear'. It doesn't equate to 'no disease', and neither to 'no cancer'. Teeth will decay, nothing to do with age. Even parts of the heart will be used up and not regenerate.
In a nutshell, the non-ageing population segment will be zombies with artificial hips, joints, teeth, heart, and so forth.

Why artificial? All the blueprints are in my DNA. On severe burn victims they do muscle and skin grafts, with sufficiently advanced technology we could grow pretty much anything. The non-ethical way would be to just clone me, zap the higher brain functions and keep for 15 years in a vegetative state you'll have all the organs to fit an adult man. The ethical way would be to find ways to grow just that organ in a lab. It wouldn't be the cure to everything as you could have brain tumors and whatnot but you could get pretty far that way.

That takes care of the first 20%... but what about the cheap AC->DC transformers that sit between your house wiring and your devices? I'd love to be able to switch each outlet I have between 110VAC/15a, 12VDC/3-5a and 9VDC/500Ma-2a, and do away with wall warts altogether.

Since you have different DC voltages you either need DC wall warts (not achieving anything), per outlet transformers (sounds expensive and turn the socket into a wall wart) or one circuit per outlet (sounds expensive and needs big conduits). And because of fire risk, property damage and whatnot you'll never get to use the same plug, tripling each outlet. Then you need something fancy to flip each socket at the source and what part of the socket is powered at the sink in a safe way, for every outlet. And I doubt 9VDC/500mW-2A matters much economically, if you want the aesthetics embed the wall wart in the wall, it'll probably be less hassle than the alternatives.

You life a life of adventure and challenge, and die young in one of the many tragic accidents that your inhospitable environment causes on a regular basis.

Fair enough, many climb Mount Everest for no better reason.

You pioneer a new way of life,

Well mostly you'll be living in a bunker living off a long supply chain from Earth. It'll be a lot like living on a submarine that you mostly endure rather than pioneer. Many will envy you going, not so many the actual living conditions.

and there's a good chance of your name going down in history books.

Name the third guy to set foot on the moon. I'm not saying there's no fame, but there's many easier ways to celebrity status. Except if you're the next Neil Armstrong.

You contribute to something that may change the course of history.

True. But I imagine it'll be a rather unglamorous and unthankful task. Remember that you're a million miles away from any fans or fame, no vacations or time off and it's unlikely any amount of money will get you fresh bacon and eggs.

And as for changing the world, they won't send you up there just to be a warm body. If you can change the world up there, you can probably change the world down here too. There's thousands of people who can say they contributed to the Apollo program, even though they never went to the moon.

Why do this in the first place?

Unlike the desktop, most people use the browser supplied with their smartphone/tablet. Apple doesn't allow any application competing with their own as far as I know and on Android Chrome is a central part of Google's all-or-nothing package of apps and services. Maybe they think that for once they'll be the default browser on something. Then again, they're not a first party browser on the desktop either so why they need to have delusions of grandeur I don't know. What I do know is that they have zero chance of pulling off a whole mobile ecosystem with apps and everything. Even Microsoft struggle like hell and they have poured billions into Windows Phone, the Nokia buyout and whatnot.

My first OCZ Vertex - the original one - I did nothing to optimize it and spent as temp drive for everything, including torrent downloads that I later archived. It does 1.5 years later after eating through a 10k writes/sector endurance, if I read the SMART data right it had 9.6k write average and 14k writes worst case. My replacement drive from WD I did all the basic stuff to optimize and kept my torrents to a HDD, it lasted about 3.5 years and the lifespan indicator said it should have another 1.5 years left but one day it just wouldn't boot.

Now I have a Vertex 450 (before you say anything it's for boot and gaming, I keep my documents on another drive...) and it has 9589 power-on hours, that's 400 days and 96% life left. At this rate, it should last 25 years or more. It seems to me they've done a lot to fix write amplification and other issues, that easily killed some of the early drives if you actually used them.

Europe is too diverse to be able to sustain a single currency without tensions that can lead to disaster.

And the US is not? Sure it's quite a bit different with State/Federal instead of Country/Union, but there's places in the US going to shit too like Detroit while others are doing well. Some 337 million Europeans use it daily, most of them for the last 16 years (exchange rates were frozen end of 1998, bank notes came in 2002) and there's one country of 11 million who might bail because they can't print their way out of a debt problem. Tough shit, but not worse than every US state has to deal with, they can't print their way out of trouble either. It's only vital if you rely on it to bail you out of loans you can't pay back.

Almost no nation can pay off all of their debts right now. The Greeks are basically being told to either capitulate or find some way, without further borrowing, to pay off all of their debts in short order. To put this in prospective, what if somebody told you that you had to pay off all of your student loans this month and your home mortgage next month. Even people with good jobs couldn't do this. The same with nations.

Bullshit. The largest creditor to Greece is the EFSF and they're not paying a dime on the principal until 2023. They're choking just trying to pay interest and no, taking up more credit card debt to pay off this month's credit card bill is not a sustainable way to go. They do have a problem in that their GDP is going down, meaning they earn less to pay interest with. That will eventually make paying back the principal harder too, but that's not their short or even medium-term problem. They can't even manage their debt, much less repay any of it.

Keep in mind that the past four years of bank loans from the ECB have not been to save Greece. What they were really designed to do was to keep the card game running long enough to let EU insiders and favored national banks unload Greek bonds, and to reduce their exposure to Greek default risks long enough to put European taxpayers onto the hook in the inevitable event of a Greek default. They pretended to save Greece, and Greece pretended to reform. And now here we are.

Yes, today >75% of Greek's debt is either the EFSF, ECB, bilateral loans from EU members or the IMF. Some was bought significantly below the nominal value though, so the net loss will be somewhat less. Of course at the time they very reasonably feared another wave of dominoes falling, either in the banking market or due to a jump in national debt interest rates. They bought time to show the other countries are past the peak and on a slow recovery and they built a giant insulating buffer. Some got bailed out, but Greece may also fall without triggering another crisis in the EU economy.

This is why I don't think Greece really understands the position they're in now compared to the position they were in a few years ago. The Greek government is pushing the EU into a corner where it would be politically unacceptable to make it look like Syriza won. At the same time everybody can see that the austerity isn't working very well, so if the EU decides it's better to let them crash and rebuild and at the same time put the blame at Syriza's feet now might be a great time. They're not just playing with fire, they've set themselves on fire and is gambling that the EU will put it out.

Millions of subscribers? You have trouble nowadays convincing people that we went to the moon in the first place. Even the worst television series has more views than any (real) space-related stuff.

That aside, watching a mars rover live is like watching paint dry. Opportunity has a top speed of 0.18 km/h and on average it has moved 10 meters a day. It spent over 11 years on a marathon that runners on Earth do in two hours. Everything else it does is equally slow, it makes a sloth seem energetic. The reason is of course that it's running on a tiiiiiiiny trickle of power, but it doesn't make for great entertainment. It's like for example CERN, you get a huge splash when they find the Higgs boson but between that it's months and years between something newsworthy happening.

And while I'm not inclined to draw a conclusion from this, it is interesting that we've had quite a few very high intelligences in our society over time. None of them have posed an "existential crisis" for the the planet, the the human race, or my cats. Smart people tend ot have better things to do than annoy others... also, they can anticipate consequences. Will this apply to "very smart machines"? Your guess (might be) as good as mine. It's almost certainly better than Musk's or Gates', since we know they were clueless enough to speak out definitively on a subject they don't (can't) know anything about. Hawking likewise, didn't mean to leave him out.

Well, maybe not the actual scientists but there are quite a few dead cultures and species wiped out because guns and bullets beats spears and claws. And I don't think anyone doubts Oppenheimer was a bright guy, even though he wasn't the one dropping the nukes. Since you mention cats, would you like an AI treating you like you treat the cats? My guess is you would not, particularly not when they decide we're too fickle and resource hungry and would rather not have cats.

The reason I'm not worried is because we have no clue on how to build systems with self-awareness. The software is running, but the computer can't look at itself in the mirror and realize I need electricity and CPUs and RAM sticks to "live". Wake me up when we have a computer that can actually refuse me from hitting the off switch.

We have a equal opportunity Calculus class -- it's fully integrated.
