People like the author often try to compare the changes ahead with the transition from an agriculture-based economy to a industrial-work economy.
What people like the author, and you, fail to understand is that the shift from agriculture to factory work wasn't much of an employment shift at all. In both agriculture and factories, there is a great deal of need for both unskilled and semi-skilled workers. For example, on a farm unskilled workers could shovel shit, and in a factory they could be hired to move heavy objects around. In the upcoming robotic society, there will be no need of unskilled and little need for semi-skilled workers. That's 50% of the workforce right there.
Sure there will always be work for highly skilled and educated people, but that only comprises perhaps 20% of the workforce. What happens to everybody else?

Well, since you clearly define "independent" as "agreeing with me" then you won't find any. That's because unlike you, scientists are generally not morons.
coal is very much needed in the manufacture of steel, aluminum and most other metals from their ores.
A minuscule amount compared to power generation.
. My point is that it's not worth wrecking any country's economy over studies that not just can, but do change over time.
None of the changes in atmospheric science over the last 20 years contradict that continuing to burn coal for electricity generation will lead to environmental disaster.
Self-driving cars don't have to be perfect, they just have to better than the average human driver.
Maybe for you, but you don't get to choose. The NTSA and the insurance companies will decide this, and will only license a robocar when it is proven to be safer than any human driver.
If I tie any car to a pole with a long rope, lock down the steering wheel and put a brick on the accelerator, it would "autodrive" around and around the pole for thousands of miles without incident, as long as you had some way to continuously pump fuel into it.
Does that make it a safe car? No, because that isn't a realistic driving scenario. Why should we believe that Tesla's tests are any more realistic? When the NTSA certifies a car as safe to drive automatically, then I will believe it.
I did. Once you reach 100km/s at 1.2mN/kW you're comfortably over unity.
Long before that the fucking battery that's driving it will run out. All perpetual motion schemes involve feedback loops that don't lose energy, which is impossible. It is that feedback loop that makes perpetual motion impossible.
The motive force involved, real or imaginary, is irrelevant.
Only as long as the external power source (e.g. a battery) provides energy. When that runs down, everything stops.
At that point, you can start drawing off energy, and feeding it back in and the energy will continue to grow.
No, the energy fed back is always less than the energy used (thermodynamics) so the feedback device you describe will slow down and stop. This applies to any motive force and has nothing to do with the mythical EM drive.
The EM drive is mythical because it is supposedly generating momentum without losing any mass.
With a constant force (constant power in), the acceleration is constant and so the kinetic energy grows quadratically. Eventually the k.e. energy goes over unity.
Total horseshit.
Every diagram that I have every seen specifies that the EM device is powered by an external source of stored energy, like a battery. When the battery runs down, the motive force stops and there is no further acceleration. Perpetual motion has nothing to do with it.
My theory is that the EM drive is like an elaborate compass needle. The microwave equipment generates a magnetic field, and this causes the device to want to align itself with the earth's magnetic field, like a compass needle does. Now supposedly the EM guys have accounted for this, but I am skeptical.
Which means being able to keep people alive in space-like environments without any connection to Earth for hundreds of years, with extreme levels of recycling and local production of consumables and parts for repair and maintenance
Not if the passengers consist of a flask filled with frozen embryos - they could travel for thousands of years with no oxygen, no food, no water and no energy consumption. Of course, you would need some technology to "decant" them (a la Brave New World), but that should be possible in a hundred years or so.
It's just a word in the English language, and as such has multiple meanings. Associating a particular individual with a particular race is pretty much impossible, but there are groups of people whose ancient ancestors came mostly from Africa, East Asia, South Asia, northern Europe. That is a perfectly valid way to define the word "race".

Non-conscious, sophisticated automation will free us.
Yeah, free us from eating decent food, living in a decent place, getting a good education etc.
Why would the 1%ers give you any more than you need to barely survive?

anf f is fixed (as claimed with the EM drive)
No it isn't. That's just something you made up.

Want to try that again in English?
Wait and see works, folks
In other words, wait until old fart khallow is dead, by which time it will be everybody else's problem.
Where's the independent confirmation?
Well, since you clearly define "independent" as "agreeing with me" then you won't find any.

Me too.

You'll always be able to drive your own car.
Just not on any tax-supported road.
I can't believe Slashdot is still promoting this scam.
Well, they sucked you and me in enough to comment.
Exactly. This is ECat all over again.
We'll be rewriting physics books soon.
We are always rewriting textbooks. How else do you expect the publishers to maintain a steady revenue stream?
It produces a force given power in.
And an electric motor doesn't?
No positive feedback => no claim of perpetual motion.
The real question here is why does it seem to work?
No, the real question is why do you believe that it seems to work?
I did. Once you reach 100km/s at 1.2mN/kW you're comfortably over unity.

Correct.
Thank God you've given up that perpetual motion shit.
I've even tried numbers pointing out where the EM drive goes over unity.
Only because you begin your argument with the assumption that the device produces constant force, and nobody claims that except you.
The drive produces a constant force
Only as long as the external power source (e.g. a battery) provides energy. When that runs down, everything stops.
At that point, you can start drawing off energy, and feeding it back in and the energy will continue to grow.

There is no such thing as race.
It's just a word in the English language, and as such has multiple meanings.

The term "race" really has no precise, globally accepted definition.
