Considering nobody here will have money, due to being unemployed, why would they want to sell their products here?

In general, in order to be successful at trade, you have to maintain a fine balance between the extremes of protectionism and the derelictions of "free trade". Not to say our policies are perfect, but just slapping down tariffs won't end well.

(On this bill itself, I'm undecided... it sounds like a simple solution, but then... there is a saying about simple solutions. The bill probably is a bit more finessed than the description, though.)

Submission + - Study shows wearable sensors can predict illness

skids writes:

Wearable sensors that monitor heart rate, activity, skin temperature and other variables can reveal a lot about what is going on inside a person, including the onset of infection, inflammation and even insulin resistance, according to a study by researchers at the Stanford University School of Medicine. ... Participants wore between one and eight commercially available activity monitors and other monitors that collected more than 250,000 measurements a day. ... "We want to study people at an individual level," said Michael Snyder, PhD, professor and chair of genetics. ... "We have more sensors on our cars than we have on human beings," said Snyder. In the future, he said, he expects the situation will be reversed and people will have more sensors than cars do.

IT security being in the state it is, will we face the same decision about our actual lives that we already face about our social lives/identities: either risk very real hazards of misuse of your personal data, or get left behind?

It's a heck of a lot less energy than liftoff from earth.

You'll note that Rosetta was able to get it's relative velocity to its target comet down to about 775m/s using gravity assist maneuvers This compares to 11,200m/s for Earth escape velocity.

The real question is whether propellant can be manufactured on the mined object (an excess quantity of which, in fact, may be the whole reason to mine) Also the large timescales for efficient transit will make the economics interestingly slow.

burdening the generation at its peak earning potential with caring for aging parents

Those aging parents are why you have as high an earning potential as you do now. They invented, built, and maintained the very society that did such things as preventing you from being murdered in your crib by roving bands of savages and giving you pernicious worldwide communications capabilities. Many still have wisdom to contribute even in senescence.

Basically the Republicans were no help at all, because their leadership and lobbyist horde made them tremble in their boots and stay in line, and the margin was so slim in the Senate that some of the more conservative Democrats were able exert outsized influence.

It almost went completely belly up when Scott Brown won Kennedy's old seat. Had that not happened, or had even one Republican dared to cross the isle, the law would quite possibly have been better. Two.. maybe even better than that.

Minerals mined here on Earth are cheap on Earth (minus shared environmental costs, of course). Given the cost to launch them into orbit, they are not cheap in space. Minerals mined on an asteroid would quite likely be much cheaper in space than those lifted from Earth's gravity well. (Also, one might find an asteroid with some rarer elements or chemicals, and "mining" an Asteroid might also be known as "hollowing out an asteroid for use as a colony, base, or port.")

Granted, the up front investment required is quite daunting.

The trick is to nudge it slightly in just the right way to use more massive bodies to cause it eventually (after much ping-ponging) to come coasting into an orbital trajectory. Which, given we are dealing with an extinction-sized chunk of rock, would have to be done very, very carefully with lots of safeguards.
