And saying "planetary system" is also too difficult?

They totally do...
Step 1: Warlord kicks your (or your family's) ass[es]
Step 2: You mine diamonds for free
Step 3: Profit!!!

I thought that the Ultimate Question was recently changed to "Where do birds go when it rains?"
Not sure how "42" factors into that, though...

Kids these days, that's what...
Now; welcome to my lawn...

The rats were all hanging out with Chewbacca

Most US companies (particularly the major networks) have distribution deals in Canada (i.e. Canadian broadcasters pay the networks to air the US content, but with their own Canadian ads)
If US networks started airing their shows online and allowed Canadians to watch on their .com (instead of through their cable-company; with US Networks getting the ad $$$ and not Rogers/Bell), then those companies in Canada would sue the US networks for loss of revenue and breach of contract.

Such a machine to read brain signals would cost a lot more than this kid's prototype.
Training the machine to read each individual's brain signals and teaching the affected individual (who can't talk to you easily, remember) would take a lot more time than teaching the affected individual morse code

Finally, fMRI machines (non-invasive way of reading the brain signals) are really expensive, and brain surgery to implant electrodes to read the signals directly is both incredibly expensive and incredibly dangerous

This kid plugged a specific microphone into an arduino, wrote some basic software, all for $80 in parts, and came up with a solution that is quick to train and (with even a small-run mass production) would be very inexpensive to build, that would give these people at least the possibility of communication with the outside world without having to have the bankroll of a well respected and successful astrophysics career.

I think it was more intended as a way of narrowing the field in an investigation

If you have a gunshot in an area with 1,000 people, 50 of whom wear bracelets (ankle or wrist), but 2 were out of the area (according to GPS), then 48 are "top-suspect"

If, of those 48, 40 of them don't have any signature even remotely gunshot-related, they can be dropped to a lower priority suspect list, and now the cops only have to find 8, instead of 40.

The easiest way to find the blue ball with yellow polka-dots in a pit full of blue balls with red polka-dots is not to search for the yellow, but to throw out the red, and whatever's left will (should) be yellow.

When all else fails, check ID; "The Burt" is the only "Bandit"

+1 This;
I thought chemical weapons/gas warfare were/are basically warcrimes nowadays, no?

["Windows" Key] + type title of launcher in start menu/screen + hit enter.
You might need to cursor up/down if you have multiple links in your start menu for the right title, for some reason.

Not sure how that's all that difficult, but YMMV

Sure, right under the big, spiky, neon-green-and-yellow balloon graphic literally screaming at you "Now with Electrolytes!"

Alternatively, ID "Smashing Pumpkins Into Small Piles Of Putrid Debris" (a not-so-famous-as-doom shareware product available at around the same time)

Why not? Buy in bulk; 10 women bound together and wrapped in plastic (for shipping, of course) can be a wonderful source of fun

There's always ways around the feed-sourced compilers; backwater compilers and such off the grid, for those who wish to print nuclear weapons, or pirate the latest hyper-interactive AI-enhanced children's story for their daughter.
