    Communism isn't inherently evil, it's just that it has often come with totalitarianism.

    Sorry, Bruce, but you're wrong.

    Communism is inherently evil; it can't work without tyranny, because it relies on idealized people who selflessly put the interest of the society above their own. This is not how real people behave. Capitalism relies on people following their impulses (even supposedly negative ones, like greed). It channels those impulses them in directions that benefit others, for example by rewarding people who produce or create new stuff. Communism wants to completely repress those impulses, so it has to force people to behave contrary to their natural inclinations. It has to indoctrinate people to follow the ideology, so freedom of speech and the free flow of ideas are forbidden. Also, communist countries don't reward producers or creators - at best, they should be happy they contributed to the betterment of society. At worst, they are regarded as exploiters, and repressed.

    I have first hand knowledge of both systems - I lived more than half my life in an Eastern European country that was theoretically "building a Communist society", and then moved to capitalist America. The difference is huge. And I know some people will come up with the "no true Communism" argument - but those are mostly folks who have never experienced life in a communist country, and can't really understand the realities there.

    I believe the best balance is a Canadian or Western-Europe style of capitalism, with strong laws and strong social support. American-style capitalism has become, IMHO, too unregulated and too influenced by money. However, with all its warts, it's miles better than any communist country.

    The problem is that Google collects all the disparate pieces of info from lots of individual third parties (each of them having only small and mostly separate chunklets of data), then centralizes and correlates them into a big data iceberg.

    People who are compromised in any way (including simple driving incompetance) will hopefully be amongst the first to decide that self-driving vehicles are for them.

    Mr. Dunning and Mr. Kruger say no.

  6. Sure, here it is:

    Let's use a frame of the reference set on the car on the left (before the collision). From this frame of reference, before the collision, the car on the left is stationary, and the car on the right is coming straight at it, at a speed of 100 mph. The total energy of the system before the collision is 0 (car on the left) + m * (100mph)^2/2 (car on the right).

    After the collision, both cars get entangled and, from the point of view of the frame of reference, start moving left at 50 mph. The kinetic energy in the system is now m * (50mph)^2/2 (car on the left) + m * (50mph)^2/2 (car on the right), that is m* (50mph)^2.

    The difference between the energies before and after the collision is m * (100mph)^2/2 - m* (50mph)^2, that is m*(50mph)^2. This difference has been absorbed by the crumple zones on both cars. Since the cars are identical, they both absorb half of it, so each car gets m*(50mph)^2/2 Joules.

    This is exactly the same energy as a single car traveling at 50 mph has to absorb when hitting an immovable wall, so the two scenarios are equivalent. The car hitting a wall at 100 mph has to absorb four times more energy, so it comes out much worse.

  7. If we choose the car as the reference frame then its velocity relative to itself (and thus also its kinetic energy relative to itself) will be zero - before, during and after the collision

    Nope, that's where your misunderstanding is. It's an INERTIAL frame of reference, so the speed (of the frame of reference) doesn't change. If the frame of reference is on the car before the collision, after the collision the frame keeps moving at the same speed, but the car is left behind. From the frame of reference the car appears now to be moving at a constant negative speed of -50 mph.

  8. GP's error was that they compared the two situations using different reference frames, when the kinetic energy formula returns different values depending on the reference frame used.

    No, there was no error, because the value calculated was the difference between energy before the collision, and energy after the collision. This difference is the same in all frames of reference.

    Here: car-wall scenario, frame of reference of the wall: before the collision: car is moving at 100 mph, wall is stationary; energy in system m*(100 mph)^2/2. After the collision, the car is stationary, energy in the system is 0, and the delta (absorbed by car) is m*(100 mph)^2/2

    Same scenario, frame of reference of the car (the frame of reference is therefore moving at 100 mph relative to earth). Before the collision: car appears stationary, wall approaches at 100 mph. Energy in the system: 0. After the collision: (the frame of reference is still moving at 100 mph relative to earth): car and wall are moving at 100 mph (from this frame of reference it looks like the wall whacked the car and is dragging it along). Energy in the system: mass of car times speed of car squared/2, that is, m*(100 mph)^2/2. The delta between the energies before and after collision is still the same: m* (100mph)^2)/2. This energy was used to accelerate the car, by deforming its crumple zones.

  9. Each car will "feel" a crash of E = m * (50mph)^2 * 2, in other words the passengers will be decelerated accordingly.

    I'm not familiar with the physical formula for "feel". But I can also explain in terms of deceleration, if you prefer it.

    Consider an imaginary vertical line drawn exactly at the point of the car-car collision. Assuming identical cars running into each other at identical speeds (and ignoring random flying bits and pieces or possible right-to-left asymmetries in the build of the crumple zones), both cars will stop exactly at this imaginary line, on their side of it. Neither of the cars will make it even a millimeter to the other side of this imaginary line, because if one does then the two cars aren't identical. Either car decelerates from its speed before the collision to 0, over a distance equivalent to the deformation of the crumple zone.

    Now, since the car stops exactly at the imaginary line, it's not relevant what stopped it there. Behind the line there may be the other identical car, there may be a wall, there may be Superman holding it in place. From the car's point of view, the deceleration is the same in all those cases.

    This shows that the effect on a car running at 50 mph is the same whether it collides frontally with another travelling at 50 mph in the other direction, or whether it collides with a wall. Since car-car at 50 mph each has the same effect as car-wall at 50 mph, it's obvious car-wall at 100 mph is a different and more damaging scenario.

  10. Can you please explain why you think I'm mistaken?

    The calculation in my post was done in the frame of reference of the Earth (or wall, if you prefer), because it's easier (since the final speed is 0). You can instead use another frame of reference (for example, of the car), but keep in mind that in any other frame the speed of the car post-collision won't be zero, so you'll need to compute the kinetic energy at the end as well, and use the difference.

  12. Two cars colliding frontal with 50 mph each, is equivalent to one car hitting a standing car (wall) with 100mph.

    It seems intuitive, but it's not true, because kinetic energy is not proportional to the speed, but to the speed squared. For simplification let's assume the vast majority of the cars' kinetic energy before the collision ends up in the deformation of the crumple zones, and compare the energies in the two cases. In both cases, the kinetic energy after the collision is 0, so by computing the kinetic energy before the collision we can find out how much the crumple zones have absorbed.

    In the car-car scenario, the total energy of the system before the collision is the sum of the kinetic energy of the two cars (each at 50 mph). Because they're identical, each car absorbs half of this, so each car has to absorb m * (50mph)^2 /2.

    In the car-wall scenario the total energy in the system is m* (100mph)^2/2; that's four times the energy of the single car at 50 mph - because the factor of two in the speed gets squared. Moreover, all this energy is absorbed by a single car (because the wall is immovable), not split between both cars. In the end, the car-wall collision pumps four times more energy in the car's crumple zones than the car-car scenario, which makes it much worse.

  14. > until we actually understand how a biological brain produces the phenomena we call 'thinking', we will not be able to create 'machine intelligences' that match or exceed human beings.

    I don't know; depends on your definitions. To me, an intelligent machine is defined by its behavior, not by its internal design or building materials. We can probably build something that behaves very closely to a human, even though internally it's built of switching silicon, or ants running through tubes.

    Historically, our machines very seldom copy nature's designs and materials. On the contrary, we have a lot of history building machines that perform a given function using different designs and materials than the natural models. We didn't understand how muscles work until very recently, but even thousands of years ago we could build 'lifting machines' that matched and exceeded human beings, using wheels, pulleys, gears and other things that don't exist in nature. Similarly, our flying machines fly faster and can carry more load than any bird, but, except for toy models, none of them use flapping wings, nature's almost universal design. So, I don't think a deep understanding of the brain function is a necessary item for designing intelligent machines either.

    Or are you saying that intelligence can only exist on a biological substrate, or that the architecture of the human brain is the only possible design that supports intelligence?If you do, I think it's a very dubious and, as far as I know, unproven statement.

    Fortunately that's absolutely not what we're talking about. People get UBI whether they work or not; with the UBI as a safety net, they can be more choosy about their jobs, or they can try this new idea they thought about but couldn't risk before because their kids would starve if it failed. Look at J. K. Rowling; she wrote the first Harry Potter book while on unemployment, but being on the dole didn't destroy her ability to achieve.

    Surely, if UBI were implemented there will be some that would just sit on the couch all day watching TV. But, once you take basic survival out of the equation, people do like to work, if the job is interesting or meaningful to them. Comparatively few people retire after they make their first million(s), even though they could spend the rest of their lives comfortably on their couches. But instead they keep working, putting in crazy hours, trying new ideas, starting new companies.

    For an example of this, see Elon Musk: after selling his share of PayPal he could have lived the rest of his life in extreme comfort, on the best couch money can buy. Instead, he started trying any number of new things, and has changed the world. Obviously, not all salarymen are potential Elon Musks, but I think UBI will free quite a bit of human potential.
