As another poster pointed out, it's just posturing for anyone to say they are going to shoot down the drones.

Not from the ground. From another drone. Don't even need to shoot, just get above it and drop something sufficiently nasty on its rotors. Collect the wreckage and sell what's salvageable...maybe even in your Amazon store.

I have one that can carry 2kg...

They're talking 25 kg / 55lbs pound load here, so you're off by more than an order of magnitude.

2nd potential mechanism. Due to competition for rare leadership positions, serfs showing leadership potential are killed outright, leaving behind only those with brains enough to do the job that the lord wants them to do. Once a dynasty and traditional economy are established, eight nor nine generations of this and you'll end up with a genetic separation between "noble blood/highborn" and "serf/lowborn" populations.

For an extreme comedic version of this, see https://www.youtube.com/channel/UCscVT3d-EEQsq-5rPozTyJw/, these English actors portrayed the four class English system perfectly, complete with simulated IQ levels.

In feudalism, and in certain forms of tribalism, the chief/King and his family eat first, and then everybody else eats what is left over from their table. (in Calapuya Chinook, the title of the chief was the Hias Mucktymuck- quite literally "the dude sitting at the head of the table", from which we get the saying "Lord High MucktyMuck"). I'd call that a very powerful selection mechanism.

I like this. It also fits the Cain and Abel hunter-gatherer vs agriculturalist interpretation.

I suspect that evolution is involved. Those who have power in society are making the decisions and thus NEED the larger brains. Those whose grandfathers were ditch diggers and under 99% of the societies ever designed would be ditch diggers themselves, didn't need big brains and in fact were better able to survive without them.

The problem is where do you draw the line?

Why is there a line to be drawn?

Photographer refuses to take photographs at a non-white wedding because of "religious" beliefs. Will take photos of any white ceremony.

And? Can the couple still get married? Can they find a photographer? Pretty sure they can. The photographer's bigotry does not pick anyone's pocket or break anyone's leg. It does not interfere with anyone's rights. Let him turn down paying customers and give opportunity to his competition, it's sort of a self-limiting problem.There is no need for any action here, any more than if a Catholic music composer accepts a commission from the diocese but doesn't accept a commission from the local synagogue (or from the Westborough Baptist Church).

Explain to us then the rational opposing position then. Explain to us the pro-discrimination position whereby we should be permitted to discrimination on the basis of race, gender, age, or even sexual orientation when none of those things should matter.

You seem to be under the mistaken impression that all things except what the state have decided are proper should be forbidden.

Yes, among enlightened people race, gender, age, or even sexual orientation should not matter. That does not imply that unenlightened people should be subject to criminal prosecution or lawsuits.

You should be permitted to discriminate in some areas because you should be permitted to do anything you want that does not interfere with the fundamental rights of others. Housing is a fundamental right, so you shouldn't be legally able to discriminate in renting out a house. But hiring a specific person to take your wedding pictures is not a fundamental right, so a photographer should be legally able to turn down a paying customer for whatever reason they want, even bigotry.

Doing the math with the wrong numbers isn't informative. You've ignored the atmospheric losses suffered by ground-based systems -- clouds, dust, the opacity of air. I think you're also being much more generous in estimating the potential lifetime of ground-based systems than space-based ones, which skews your numbers.

It may be that the gains are small enough to not justify the launch costs, though that depends on how much we value land taken up by solar arrays.

I thought I'd never see you write those words. You are completely correct, of course..

The reason for the crushing of liberty is the cash cow. Profit first, politics later.

Ted Cruz is a Canadian.

Was astounding. Especially since I heard at least three better plans- community sponsored healthcare (in which LOCAL taxes fund LOCAL facilities with LOCAL doctors, managed like schools used to be with a local hospital board), subscription based healthcare (in which the rich pay more to fund clinics for the poor, but everybody pays what healthcare really costs, not job based but rather what it costs to have doctors on duty in clinics and hospitals, whether you are sick or not), and finally, free market health care (with no middle man, but again, no assurance of care).

Of course, all three of these cut out the insurance middle man cash cow- who was Obama's cronies as well as the cronies of certain key Republicrats. Can't hurt the cronies, so once again any form of subsidiarity goes on the back burner in favor of federal control.

And now it comes out he was under medical treatment for depression. This is suicide. With murder.
