An other is: can they take snapshots of what one system learned and transmit that to an other ?
If they run on general purpose software, you can just clone the entire program. Matrix style learning is a lot more difficult, because it has to be integrated in what the person already knows.
Big rocks don't necessarily kill all humans either. Previous big impacts didn't kill all life on earth either, and they didn't have an early warning, or capability to build deep underground shelters.
why even bother worrying about AGW, since even by the worst predictions it won't have any horrible effects for the next 100 years or so
Some bad effects are already starting now, and depending on your age, your children or grandchildren may be hurt by it. Worrying about your direct offspring, that you know and love, makes a lot more sense than worrying about descendants 50 million years from now.
Off the shelf, benchtop lasers can easily produce 2.5 J pulses in 10 ns
So where is the disconnect ? If such a benchtop laser can produce 2.5J pulses, and we only need 0.2J to damage steel, how come the article says we need lasers the size of football fields ?
This is a joke. Takes them half a minute to burn through black rubber, and the boat wasn't even moving. Now imagine it is twisting and turning and splashing water on the hot spots.

Touch screens do not work that way! Good night!
Not normally, no, but it could be added as an extra feature.
if modern civilization is going to advance we need to grow culture in ways that counteract both these effects.
Who decides what is considered "advance" ?
1. The voter selects a candidate on a touch-screen tablet.
Ah, I see you're building a finger print database. Nice.

What I do not understand, why is it so important to replace the voting process with an electronic voting process
Because it makes it much easier to rig the elections.
So, the only bad part about the microbeads is that they concentrate the toxins in the beads ? How much of a difference does that make ?
If you remove the guts from the fish, you'll also remove the microbeads. And if not, you'll just poop them out.
Also, guts don't just sit there, they digest stuff. That includes pulling toxins attached to the beads into the blood stream of the fish.
The toxins are the problem, not the beads.
Lots of toxins are bioaccumulative
No, only a few toxins are, most notably PCB and mercury compounds.
they're hard to clean up
They'll clean up by themselves, either biologically, chemically, or abrasively.
then the fish are eating them and then you'll be eating it.
Do you eat fish guts ?

People aren't so much scared of what could happen as they are about inability to do anything about it.
That's silly. If you can't do anything about it, there's no purpose to being scared.
This is not a minor injury for a civilization. This is death
Death is death. Doesn't matter if you die because you got hit by an asteroid or a car.

Well, it's happened a couple times before
Mankind's ancestors survived every single one of them.
Starbucks uses the same feature. A big reason for drinking Starbucks is to show other people that you can afford it.
They could have added $1000 to the price. That's always a popular Apple feature.
You can make money with arbitrage, and do society a benefit at the same time.

Here's a demonstration of the effects of a 10 kW laser on a black rubber boat.

Use a material that burns without leaving a residue.
stainless steel gets damaged at about 0.2 J/cm^2
To produce a 0.2J pulse in 10 ns requires a peak power of 20MW, plus a beam that stays within the cm^2 over a long distance.
Put a cover on it. The laser vaporizes the cover, and then hits the clean reflective layer underneath.
laser ionizes a trail from the laser to the target device. then you send a bolt of lightning down that air column
That only works if the target itself is grounded, and the channel isn't too long.
Use a thin film of beryllium deposited on a thicker layer of copper to spread the heat.
