3D printed objects aren't the strongest due to the way the layers are laminated together. I imagine the last place you'd want a weak join is on a 150+ foot long blade swishing through the air.

You betcha.

Especially since a spinning blade gets more efficient as it gets faster. Higher speed = lower torque for a given horsepower density, so a higher tip speed ratio (TSR) wastes less energy "twisting" the air downwind.

Efficient wind turbines run at a TSR of 6 or higher - which means that in windy conditions the tips are running at an appreciable fraction of the speed of sound.

If one of those puppies breaks off it's NOT the kind of baseball bat or boomerang you want coming toward you, whether flying or summersaulting along the ground. (Imagine a caber toss with giants and redwood logs.) Not to mention what the resulting unbalanced spinning does to the other blades and the pylon.

Yeah, let's just ignore that little crash in '99 and 2000

What crash would that be? Unemployment was under 5% in 1999 and kept falling until 2001 (graph). Yes, it was bad if you were in the tech sector. More of a market correction than a crash. <Cue Crocodile Dundee> Now, 2008, THAT was a crash!

So, who benefited from that "boom"? The very same people that are benefiting from this one, and it ain't us.

Indeed, which is why I'm voting Sanders.

Here's an amusing thought: Trump has threatened to run as a third party candidate if the Republicans are mean to him, Bloomberg said if Trump, Sanders, or Cruz were nominated he could jump in. So it could be a four way race; Trump, Sanders, Bloomberg, and Cruz. I don't think that's ever happened before.

Bush and Christie hitting one-time Senator Rubio out on lack of experience when Bush's Texas governor brother took the white house in peacetime with a balanced budget and in a boom and left with two wars, the worst economy since the Great Depression, and history's largest deficit. Then a one term Illinois Senator took that and is leaving office with low unemployment, a lower deficit, and a good economy. They're nuts.

Not that Rubio is any more sane.

x64 actually runs x86 code more efficiently than classic x86 due to the large number of registers available for renaming on x64 which is why you can see significant improvements switching from the x86 to the x64 build of any of the MS OS's on exactly the same hardware with exactly the same applications (no recompile needed). The only thing you give up is a bit of storage (on the OS side) and a bit of ram so it won't work for $200 tablets but for anything with reasonable specs it makes sense.

The difference is what can be done about it.

If the market decides that it's not important for people to have this, then the only way to change that is for the people who need it to somehow become rich. If the regulators decide people shouldn't have this, then the voters can change that. And if you factor in the increased independence and productivity of the recipients, it might not cost that much.

Of course the way we do it now is we force employers to make accommodations. That's better than nothing, but statistically the public is still paying; the burden is just randomly concentrated on a few unlucky employers.

Since when have we reached the point where you aren't allowed to annoy or offend people?

Since never. You're still allowed to offend people, but it's never been the case you could do that with impunity.

The only thing that has really changed is that communication on a mass scale is literally too cheap to meter. That means putative offenses and the dudgeon that follows on them can spread across the globe in minutes rather than taking days or weeks to spread through your immediate circle of face-to-face acquaintances. So without people changing one bit, the circumstances in which they interact in have changed dramatically. For things to go back to the way they used to be people would actually have to stop being the same as they've always been.

Well good luck with that. People tend to be stubborn idiots. College students tend to be inexperienced stubborn idiots. That means they're trying to find their place in the world, and the way an inexperienced idiot would do that is to try to change the world. And if there's enough of them working together (using cheap global communications?) then they might even succeed. Sometimes that's even a good thing, but it's never pretty.
