Copyright, maybe. patent: hell no. MIght as well say Stephen King could patent his books.

SO now vs. SO 15 years ago reminds me of the old "Eternal September" meme. The traffic is up 1000% and the number of reasonable questions (not the fraction of traffic) is down 90%.

That said, it's sadly predictable that, every time a company gets sold, the new owner decides profit margin is too low and clearly it's the fault of all those no-good slacker employees.

Because Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.

So, your homework assignment is to calculate the total volume in, say, 175 to 190 miles altitude and +/- 20 degrees latitude. Compare with total volume of ALL satellites in any orbit

That's no moon! ( or world)

Here I am, first to point out that growing teeth like this will certainly lead to...

Vagina Dentata

The number one most destructive and resiliant species? Homo Sapiens.
All the other species are just trying to survive the worldwide spread of said species.

Schrodinger's Box is completely full of cat until you observe it, and then there's a solid cat in one corner.

For those interested in a vision of a world with an advanced version of this technology, read Scalzi's "Lock-In" series of books.

Wrong again. This is your homework assignment: to simplify it for you, take an object moving in a plane (2-dimensions) and demonstrate how to change the speed without changing the direction.

The original author as well as this reviewer appear to have no idea what "intuition" means. No mathematician ever intuited anything without first learning things and learning how to examine things.

More to the point - just look at some of the famous problems like the 4-color conjecture or Fermat's Last Theorem --- or even whether pi^e is transcendental. "Intuition" only holds until the proof or disproof is found

You are clearly a youngster. Yes, even in the 60s and 70s airline tickets had names on them, but there was no ID check of any kind. In fact, the director of the SkunkWorks (per the book he wrote) bought tickets to Europe under the name "Ben Dover" to avoid public knowledge of his travel.
The original intent, and only justification for, passenger manifests was to be able to alert family members in case of a crash.

My TV is "dumb," i.e. I do not connect it to a LAN, let alone the internet. What risks, if any, do I incur by continuing to use my Gen1 Chromecast to receive streams from VLC playing videos on my laptop?

Every time a new mechanical, or even partially mechanical, lock comes out, one craftsman or another finds a way to build the mechanical key -- or to bypass the key mech (see, e.g. "bump key" for standard tumbler door locks).

Software's even worse, because it's damn hard just to make software do what you want it to do, let alone NOT do everything else in the universe. Ultimately it comes down to a cost-benefit ratio. We don't bother with DoD-class crypto phones for everyday use for that reason. We don't install bank-vault quality timelocks on our home doors for that reason.
At some point, the best you can do is air-gap the systems that need total security, vet the crap out of all users, and hope & pray spies don't get in. So far, not a single government in the world has managed to keep spies from getting jobs/assignments it top-levels of gov't management.

Sure, but which square root?
(yes, I'm aware that France has had dozens of capital cities over its history)

If these geniuses lost money buying up microbusinesses, that means the folks selling off said items got paid more than their property was worth. Win!
