I actually lean on your side, I think free easy access to knowledge is awesome and is for the best, but to put a counter example, there was a Hackernews not too loNguyen about how the top result for election on Google was to a false news side.

So I do think we'll have issues controlling that false information doesn't spread faster and wider on the Internet then true info.

They can always jam whatever bands it operates on. They can make it illegal to tx/rx in those bands.

I'm imagining a super narrow directional beam pointed at the satellites. You cannot jam that, and even detecting it would mean you need to be really close. It can still be made illegal, of course.

I don't know what technology you need to track and hit low-orbit satellites with a narrow beam, but I bet it's not as cheap as a dish?

It is not unthinkable that the NSA has faked the moon landing and pictures of earth with photoshop / film equipment. You havent been above earth, so how do you know? I think you should be less arrogant at the prospect of somebody having a different opinion than you. Even the astronauts could be fooled, remember that they only ever see space through a sheet of glass, whether it's from inside the space station or their…

You can also just see the moon by staring at the night sky.

Donald Trump, potentially. We'll see.

> People give examples like immigration

They don't know what they're talking about. Migration isn't even a particularly modern phenomenon.

napkin math (chemistry style): (4425 satellites * 23Gbps) / ((60,000PB of fixed internet traffic / 1 month [1]) * (12 months / 365 days) * (1 day / 24 hours ) * (1 hour / 60 minutes) * (1 minute / 60 seconds) * (8 bits / 1 byte) * (1024 Tera / 1 Peta) * (1024 Tera / 1 Giga)) = An astounding O(54% of global internet traffic) [2]! Obviously there are many many more variables in this [3]. Nonetheless this will be super…

Half of those satellites will be over the Pacific Ocean at any given time.

On the bright side, this completely solves the bandwidth for adventurers. The farther you are from civilization, the less contention for the links.

Fake news targets people based on popularity if you look at the popular vote Hillary was actually more popular and thus the biggest fake news target. They're going to destroy Trump next it's not about politics it's about traffic and money , he's setting himself up perfectly to get torn to shreds if he can't deliver on practical issues like jobs and health care costs, if he brings in single payer he won't be so vulner…

> Most likely he's planning in using scapegoating to have to cover for throwing his followers under a bus in order to please Wall Street.

With Steve Bannon he has the best man on board to do exactly that /without even alienating his followers/, at least the loyal ones. We might see a propaganda alliance between the White House and far-right media, so it's not at all clear to me that Trump will be destroyed by fake news.

Free, global internet access is the next step toward a smarter, more progressive planet. I don't even care about the speed - if the only thing users could access was wikipedia, I'd still personally donate to the project. I cannot emphasize how important democratizing knowledge is to me (and many others).

Sadly, this is a naive view, and perpetuated by people who wants to push more ad channels in the name of "empowering" communities... Access to information does not mean consumption. If you give access to internet to 100 people, 99 of them will use it for Facebook or Porn. 1. If you have enough motivation, learning about anything was already possible even before Internet (local libraries and resources) 2. If you don't…

"If you give access to internet to 100 people, 99 of them will use it for Facebook or Porn."

This isn't a zero sum game, last night I used my internet access for porn, today I'm using my internet access to learn about a new 4,000 satellite constellation being built by SpaceX, later on today I'll use it to create a pull request on Bitbucket.

15 billion to develop and deploy to space over four thousand satelites (not ignoring the fact that developing the prototype costs orders of magnitude more than simply assemblying the rest) seems like a gross underestimation...

If they can put up 20 sats per launch, that's a cost of $75m per launch. With first stage re-usability each launch might cost ~$35m, leaving $2m to pay for each of those 20 satellites. This isn't taking into account the cost of ground stations and operational costs such as personnel, but it doesn't seem completely outlandish.

Lunatic, perhaps, but "fringe" actually does imply numeric inferiority.

no in politics it means on the extreme end of a spectrum eg the KKK or the equivalent on the left who where calling for the workers of the world to help our Baathist sisters and bothers crush the uprising.

It's both. It's a visual metaphor for the edge of something, such as the fringe of a curtain or scarf.

Something should be both extreme ideologically, and a relatively small minority to be "fringe".
