    Filling up landfills with carbon is a very inefficient way to deal with CO2 in the atmosphere. Landfill space, near urban areas (where the trash is generated), is at a premium. There is more than one pollution issue going on at a time. Filling up landfills with paper will scarcely make a dent in the CO2 in the atmosphere.

    Ooops, they banned those in CA as well....

    Which worked really, really well! With the success of that law, nine other states are currently planning on copying.

    As right-wingers love to lecture, nothing is "free", those "free" bags cost money, and since retail is a highly competitive, low margin business, those "free" bags had gotten so cr_ppy as to be almost worthless - requiring multiple bagging to hold anything of any weight, if they would even then.

    Now, if you need a bag, and don't want to pay $2 for one of those nice sewn waterproof fabric bags at the checkout counter that are indefinitely reusable, you can buy a disposable plastic bag for a dime. And that bag is so nice, being large and sturdy, that it can be reused indefinitely. Throwing away piles of flimsy one-use bags is a thing of the past.

    I would object strenuously if someone proposed going back. It is much better without those "free" bags.

    I generally agree with the thrust of your comment, but your last sentence refutes your first one. We really don't know how intelligence works, or even have a good definition of what it is, still, so your confidence that neurons that maintain homeostasis have nothing to do thinking is misplaced. In fact there is very strong evidence that these background task neurons are also very important in thinking - like in maintaining consciousness. Disruptions in those low level background neurons do not usually interfere with just the autonomic functions but leave consciousness alone, instead consciousness bites the dust first.

    How many transistors in the human brain?

    Of course the answer is zero, because the brain has neurons. But we can have some numbers for comparison. A Graphcore GC2 IPU has 23 billion transistors. In comparison, a brain has: 100 billion neurons. 10 trillion synapses. 300 billion dendrites. Which of those need to be emulated? A transistor does not do as much as a neuron, and we don't know all the things a neuron does. There is some evidence that the inside of a neuron does some kinds of calculations.

    There is a lot more than "some" evidence of that. The behavior of a single neuron is quite complex, much more like a CPU than a transistor. We haven't worked out the processing of even a single neuron. There is very good evidence that even individual synapses perform some sort of computation - their response is a function of a number of local chemical factors, i.e. it is a weighted computation, and is not simple like a transistor.

    Neural systems (except for the simplest peripheral reflexes perhaps) are statistical computing systems at every level, and there are many levels (you list three, but there are likely more that are not as obvious or easily enumerated. The equivalent of a "neural" component in a AI neural net is more like a synapse than a neuron.

  7. The Real Obstacles To Be Overcome on As China Option Fades, Bill Gates Urges US To Take the Lead in Nuclear Power, For the Good of the Planet (geekwire.com) · · Score: 5, Interesting

    Gates's focus on new, un-proven, and frankly more complex fission reactor designs is hopelessly misguided. A much better idea was the Gen III+ approach of standardized units that are improved lower cost versions of proven PWR technology, like the Westinghouse AP1000.

    And no, it is not "opposition to nuclear power" holding it back in the U.S.

    The primary problem is and has been the high capital cost of the plants. Without regulation guaranteeing sufficient stable returns over a long time to recover the investment it is a difficult pitch, and even then the long pay-back time makes it less desirable than natural gas plants if that is an available option. How to make capitalists and investors want to sink their money into these plants in large enough numbers to be helpful?

    And this problem has led to the second - so few plants built that the industry to do it has become moribund, thin and the supply chain brittle.Westinghouse, the developer and backer of the AP1000 plant went bankrupt two years ago.

    The U.S. has had a stream-lined licensing process for a few decades now, and since 2008 seven new units were licensed - all of the AP1000 design. Investors/utilities have dropped out of five of these, and the projects are dead. None of these projects were killed by "opposition", it was due to the projects going over budget and becoming uneconomical, and Westinghouse going bankrupt, not problems an untried new technology is likely to fix.

    Only the two Vogtle units are still being built and have gone massively over budget. How far over budget? The original estimate for the two units was $4.4 billion and is now expected to be $25 billion. In large part this is has been due to difficulties in getting the major parts manufactured, and errors in construction, requiring rework, and delaying the schedule. And this is due to the brittleness of the industry supporting it at this point.

    An AP1000 is running in China right now (started up in June of this year) and three more are under construction, but these units have also been delayed by years due to supply problems

    The nations that have either a) built a mostly nuclear electricity grid (France); b) are actively building many nuclear power plants (China); or c) have a well-proven track record for building plants on-time and budget (South Korea) have one key thing in common. All of the companies doing this are majority government owned. That is to say, they are socialist enterprises.

    The capitalistic model of the U.S. for nuclear power has failed. It has not maintained economies of scale, has been shown robustness to overcome "teething" problems, and is unable to "take a bath" on early units to perfect the supply system and overcome the learning curve.

    It you want to see nuclear power making a come back in the U.S. the only option, on the evidence, would be creating a government run corporation to build them. If you don't support that, then you don't support nuclear power. And complaining about NIMBYism, or environmentalists, as if they were stopping nuclear power is simply beating a convenient whipping boy. Makes you feel good inside to bash people you don't like, but accomplishes nothing.

    The term "toxic metals" would be a much more accurate term since "heaviness" really has nothing to do with it. Lithium, which is on your list is the lightest of all metals.

    Because they define all successful economies as "totally capitalist, man!" and all failed economies as "proof of the universal failure of socialism everywhere". In other words it is plain dishonesty. All economies in the world of any size are mixed economies, with some level of regulation for the capitalist component (and the socialist component as well, for that matter).

    They are not "kicking our asses". The only European countries ahead of America on either median income or per capita GPD are Norway, Luxembourg, and Switzerland.

    Norway has a small population and plenty of off-shore oil. Luxembourg and Switzerland have tax shelters and international banking.

    It should be well known at this point that the higher per median capita income of the U.S. is largely due to a few things.

    The most important is the Americans work longer hours than any other advanced economy. This is largely not voluntary, try taking extra time off from your job and see how that goes for you, career-wise.

    The other is that the U.S. has an extremely unequal distribution in income, approaching third world kleptocracy levels. Thus a good chunk of that "median income" is in the hands of very high income people.

    And finally the EU spends 9.5% of its GDP on health care. The U.S. spends 17.9%, with no better results (in many cases worse). So about 8.4% of the "higher" median income is being sucked down a black hole of corporate inefficiency.
