Please, see these charts from Mother Jones on income inequality in America. It's not that the rich are getting richer, its that the super-rich are getting super-richer...and leaving the rest of us behind.

But from this comes an incredibly insightful comment from my dad:
Let’s begin with energy efficiency. One of the most remarkable facts about the human brain is that it requires less energy (12 watts) than a light bulb. In other words, that loom of a trillion synapses, exchanging ions and neurotransmitters, costs less to run than a little incandescence. Compare that to Deep Blue: when the machine was operating at full speed, it was a fire hazard, and required specialized heat-dissipating equipment to keep it cool. Meanwhile, Kasparov barely broke a sweat.
The same lesson applies to Watson. I couldn’t find reliable information on its off-site energy consumption, but suffice to say it required many tens of thousands of times as much energy as all the human brains on stage combined. While this might not seem like a big deal, evolution long ago realized that we live in a world of scarce resources. Evolution was right. As computers become omnipresent in our lives — I’ve got one dissipating heat in my pocket right now — we’re going to need to figure out how to make them more efficient. Fortunately, we’ve got an ideal prototype locked inside our skull.
To support a human brain you can't just factor in the calories consumed. You have to factor in the costs in energy to grow the food, etc.Here's what Dad is driving at: in order to sustain Watson for an hour, you might need 50 kilowatts of power, to pull a random number out of the air. To sustain a Ken and Brad's brains for that same hour, you'd only need 24 watts of power.
I think this reader is right. It seems like there are three parts of the Enterprise computer that we are talking about: the human-machine interface (i.e. Dr. Crusher and the female computer voice interacting), the voice-recognition software that does what Watson did this week on Jeopardy, and the memory, which contains basically the entire history of several civilizations as well as every science and engineering fact ever known.
I watched the PBS documentary on Watson last week and what struck me most was just how close we are to a Star Trek ship’s computer.
Being a fan of The Next Generation, I loved watching Beverly Crusher go back and forth with her sickbay computer to diagnose a medical issue. You could see flashes of inspiration in Beverly’s eyes as the computer made connections that she had no way of making because it was tapping into to resources and databases her human mind could never store internally (or never even know about). But the “ta-da” moment came from Beverly as she connected the dots herself, and then bounced her logic off the computer to make sure it was sound, sometimes going several rounds before working it all out. Watson seems very close to being able to fulfill that kind of promise.
The documentary touched on a possible new type of “big picture” researcher. A scientist or doctor that uses a Watson-type interface to make connections across various fields of research; connections that specialists might never make because of their narrower focus. As long as a person is trained on how to ask the questions, the Computer can pull answers from all available sources and suggest multiple related items that might never have been considered before.
The potential is extraordinary, right?
In 2005, the online chess-playing site Playchess.com hosted what it called a “freestyle” chess tournament in which anyone could compete in teams with other players or computers. Normally, “anti-cheating” algorithms are employed by online sites to prevent, or at least discourage, players from cheating with computer assistance. (I wonder if these detection algorithms, which employ diagnostic analysis of moves and calculate probabilities, are any less “intelligent” than the playing programs they detect.) Lured by the substantial prize money, several groups of strong grandmasters working with several computers at the same time entered the competition. At first, the results seemed predictable. The teams of human plus machine dominated even the strongest computers. The chess machine Hydra, which is a chess-specific supercomputer like Deep Blue, was no match for a strong human player using a relatively weak laptop. Human strategic guidance combined with the tactical acuity of a computer was overwhelming.
The surprise came at the conclusion of the event. The winner was revealed to be not a grandmaster with a state-of-the-art PC but a pair of amateur American chess players using three computers at the same time. Their skill at manipulating and “coaching” their computers to look very deeply into positions effectively counteracted the superior chess understanding of their grandmaster opponents and the greater computational power of other participants. Weak human + machine + better process was superior to a strong computer alone and, more remarkably, superior to a strong human + machine + inferior process.
Dr. Crusher seeks to solve a medical mystery. She sits down in her sickbay, silent. She appears to be concentrating very hard. Little flashes of inspiration cross her eyes. In less than a minute, it is over. She stands and prepares a new hypospray, which she administers to the patient, who immediately recovers. Ground-breaking medicine has become a silent exercise of human creativity directly coupled to raw computational power.
At the end of the day, Dr. Crusher unplugs herself from the system, and puts the external component of her human-machine interface (the power supply and antenna) in a charging socket. Though it can provide her with days of power, she likes the act of plugging it in every night. She likes to disconnect herself (she feels it helps her retain her 'humanity'), and she likes the antiquated notion that daily recharges are still necessary.Is it really so far-fetched? Why are we spending countless hours developing better and better human-machine interface software, like Watson's interface, when we could be potentially circumventing the need for it by developing better human-machine interface hardware?
Or contemplate this: To reach even the more modest target of 450ppm, reports David Biello, the IEA says humanity would have to build the following every year between now and 2050:He goes on, discussing the economic implications of that project:... 35 coal-fired and 20 gas-fired power plants with carbon capture and storage; 30 nuclear power plants; 12,000 onshore wind turbines paired with 3,600 offshore ones; 45 geothermal power plants; 325 million square meters-worth of photovoltaics; and 55 solar-thermal power plants. That doesn't even include the need to build electric cars and hydrogen fuel cell vehicles in order to shift transportation away from burning gasoline.
From what economists tell us, it looks like the worst thing policymakers risk on climate change is somewhat slower economic growth. One way or another, we're getting wealthier.
This represents what is perhaps the foundational faith of modern economics: a faith in human adaptability and ingenuity. Especially via the distributed decisionmaking represented by open markets, humans can master almost any circumstances given time. (For a recent example of this optimism on Grist, see economist Matthew Kahn.)
Nowhere in these models will you find any hint of Diamond- or Lovelock-style apocalypse. Instead, future people will be much wealthier and, because of that, better able to cope with the problem.
We are stumbling around in the dark, in an area where scientists tell us some very, very nasty beasties dwell. In that situation, it seems to me the overwhelming bias should be toward action -- getting lean, mean, and nimble enough to handle ourselves no matter what slouches our way.So if the politicians tell us there are very, very nasty beasties in the dark, we attack immediately, without hesitation and without proof of the beasties actually being there. But if scientists tell us of beasties in the dark...politicians demand more proof.
The new cadre of Republicans in Congress is packed with climate change sceptics, several of whom have promised to use their power to cast doubt on the underlying science.Seriously? "several of whom have promised to use their power to cast doubt." I don't know about you, readers, but I never voted for an elected official yet who had "the power to cast doubt" in their job description. The obvious implication here is that not only are the scientists who have provided evidence of anthropogenic global warming absolutely wrong, but also it is the imminent duty of the Republican Congresspersons to show that wrongness (and their own
"Moreover, the rocket industry's status as a colossal government-funded program with seemingly eternal lifespan has led to a situation in which its myriad contractors and suppliers are distributed over the largest possible number of congressional districts. Anyone who has witnessed Congress in action can well imagine the consequences of giving it control over a difficult scientific and technological program."
[C]onsider Lockheed Martin’s sheer size for a moment. After all, the company receives one of every 14 dollars doled out by the Pentagon. In fact, its government contracts, thought about another way, amount to a “Lockheed Martin tax” of $260 per taxpaying household in the United States, and no weapons contractor has more power or money to wield to defend its turf. It spent $12 million on congressional lobbying and campaign contributions in 2009 alone. Not surprisingly, it’s the top contributor to the incoming House Armed Services Committee chairman, Republican Howard P. “Buck” McKeon of California, giving more than $50,000 in the most recent election cycle. It also tops the list of donors to Sen. Daniel Inouye (D-HI), the powerful chair of the Senate Appropriations Committee, and the self-described “#1 earmarks guy in the U.S. Congress.”Have a great day.
Add to all that its one hundred and forty thousand employees and its claim to have facilities in 46 states, and the scale of its clout starts to become clearer. While the bulk of its influence-peddling activities may be perfectly legal, the company also has quite a track record when it comes to law-breaking: it ranks number one on the “contractor misconduct” database maintained by the Project on Government Oversight, a Washington-DC-based watchdog group.
