No, it doesn't. Not really. It doesn't recalculate, it doesn't automatically advance, etc. It's got turn by turn directions like printing off a Google map at home does.
Google insisted they couldn't do turn by turn navigation on the iPhone, then went and did it in Android. That alone should have been enough.
How much do you want to bet Google is madly working on an iOS maps app right now, with all the features of their mapping service on Android? Wait a few months and iPhone users will likely have much better free mapping solutions than they did a month ago.
Google Maps has lots of glitches too, and there were a lot more when it was new. Google maps usually misdirects me about one time in three, either by plotting addresses in the wrong part of the city or by trying to send me the wrong way down a one way street.
"Is helium really the only way to cool MRI machines?"
Currently, yes. It's presently the only practical way to get a reliable large scale high field superconducting magnet. It's easy to say someone will invent something. That something is a high temperature superconductor (that is malleable enough to be made into wire and wrapped into a coil). People have been working on that for a long time without a lot of success. Are you feeling lucky?
You're right. The statement should be amended: "if you're not paying for it, you are either the product, or nothing."
Scientific Linux is a linux distribution that's made for a specific group of people (who DO pay for it, possibly indirectly). Because they're nice people, they let you download it too. But you're not the customer and they don't owe you anything. You're nothing.
Actually, modern cosmology and quantum mechanics does a pretty good job of reducing everything. It's to the point where the creation of the universe can be explained by a quantum fluctuation with the energy equivalent of about 10 lbs of matter. That leaves only the laws of quantum mechanics as an unexplained prerequisite, and lots of people are working on explaining even that.
Those societies eat a lot of dairy products and eggs. You mention eggs yourself. While the popular definition of "vegetarian" includes people who eat animal products other than meat, since we're talking about evolution we have to use a more objective definition, which is closer to vegan: if you eat animal products you are not a vegetarian.
You'd have an awfully hard time being a healthy non-animal product eater without using artificial supplements and only native local plants. It's not a lack of overnight delivery of vegetables that's a problem, it's things like nuts, fruits and particular plants that contain difficult to obtain nutrients. It MIGHT be possible to live on a pure locally sourced plant diet today given your choice of location, an appropriate collection of alien species, and the resources to do things like irrigation, but this wasn't an option in the past.
"The rest supplement with their vegetable matter with a great deal of dairy."
Which isn't vegetarian in any objective sense. As far as the universe is concerned, if you need animal products you're not a vegetarian, whether you acquire those products by carving off chunks, milking, or repeatedly pulling off lizard tails.
"When a mutation causes something that is less favourable, e.g. reduced fertility, it originally would have meant that individual had less offspring and the mutation would die off."
Fertility treatment is expensive. The vast majority of people in the world can't afford it, and the ones who do get it almost always have fewer than the average number of children. If the fertility problem is genetic, it's very unlikely that inheritors of that gene will outcompete others over several generations.
"This favours the propagation of genes that result in less clever people."
Which is evolution, alive and well. Just because your own personal biases don't agree with objective fitness doesn't mean evolution isn't working.
"I'm always sensitive to any claims of "mutation X gave humans power Y" because mutations are so rarely beneficial, the majority of evolution comes from sexual inheritance and selection pressure."
Where do you suppose the genes you get from sexual inheritance come from? Intelligent design?
ALL evolution comes from selection pressure. That's what determines which mutations, and combinations of genes created by sexual inheritance, survive.
One random gene in one birth doesn't suddenly affect a population. It spreads through a population because its possessors have an advantage (selection pressure) and have more babies who inherit the gene.
If you're eating dairy products or eggs, you're not a vegan (look back to where the thread started). In regards to this story, you're also not a vegetarian in the proper sense - you're dependent upon animal products.
There are reports from the 70s that gave remarkably accurate timelines given different funding scenarios. Since then we have funded fusion research at less than their lowest projections and have achieved a bit more, more quickly than they estimated.
There is no kernel of truth, unless its regarding what journalists and uninformed critics say.
"But there is no frame of reference in which anyone is traveling 2c."
I didn't say there was.
So when you say, "...their relative speed was 2c, from the perspective of the third ship," what you're saying is, "From one observer's frame of reference, trying to do calculations for another observer's frame of reference, using Newtonian physics, the speed will be 2c."
No, I'm not. The third ship measures distance and time entirely in it's own frame, with no regard for any other frames and finds that the two ships have travelled one light year apart in half a year.
Anyway, the entire analogy is unneeded. We see the evidence of warp movement all around us in the cosmic microwave background, and the universe hasn't ended in a puff of smoke because of causality violations.
Fusion research is most likely somewhat ahead of where predictions made in the 70's said it would be, given the funding (decreasing) it has received since then. The "always 50 years away" thing is a stupid meme.
Special relativity limits only the speed through space. Actually, it only says that you need an infinite amount of energy to accelerate to c. In inflation, space is expanding. Nothing is moving through space at anything like c.
Special relativity does NOT say that FTL travel is impossible, only accelerating to c in normal space.

Strange, the Apple maps app on my phone has walking directions. Maybe you haven't looked closely?
No, it doesn't. Not really. It doesn't recalculate, it doesn't automatically advance, etc. It's got turn by turn directions like printing off a Google map at home does.

The mods think you're being funny. I really hope they're right.
Quantum fluctuations are random. One that big is very rare, but it can certainly happen.
The universe may very well have a net energy of zero, or very nearly zero. (Hawking, A Brief History of Time, pp. 129)
Amazon did it with the Kindle. I think some of the other ebook reader companies did as well with their Android flavours.
Interesting. Can you name one operating system that has become successful via it's use of ads for a third party?
You're right. The statement should be amended: "if you're not paying for it, you are either the product, or nothing."

Despite the Latin, you seem to have overlooked the word "could" in the GPs statement.
Ah, you've discovered the birth of civilization.

Ridiculous? Population contraction speeds the spread of beneficial genes through the gene pool.

Where do you suppose the genes you get from sexual inheritance come from? Intelligent design?

Not true. There are other places where they ship locked, if you buy them on contract. Canada, for example.
Everybody should learn to code because everybody can benefit from it, just like we finally decided everybody needed to learn how to type.
Just like you don't let the guy who can't spell write the annual report, you don't use the poor coders' code for anything critical.
