Don't worry - give it a few generations and the people in charge will have accumulated enough experience to handle the access to knowledge.

Mainstream social media is pretty much curated at this point.

Mostly by your selections in the media. And the good stuff isn't getting filtered out, just lost in the noise of the bad stuff.

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

No, what you are looking at is a giant cardboard cutout held up by thousands of Mylar helium balloons and pulled by a herd of cats connected with fishing line. It also explains the "super moon" effect; the cutout actually is closer, and therefore larger, when the helium supplies start to run low every few months or years. #learneditontheweb /s

You can't herd cats. theory debunked

There are 5 planes of 75 satellites planned by SpaceX later on for 81 degrees inclination which might be sun syncronous during the day but the initial 32 planes of 50 satellites are all headed for 53 degrees inclination which I'm sure isn't. You can't have sun synchronous orbits anyways for those satellites providing coverage during the night.

Well, I mean you can put a satellite in orbit so that it always goes over the equator at midnight local time. But then it's solar panels will never get any juice and it won't function.

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).

I used to think that until smartphones became inexpensive ~3 years ago. Now twitter and facebook have stupidity poured into them rather than the people learning from it.

Seems a logical step for SpaceX. One of the biggest challenges facing Mars colonization would be internet connectivity over such tremendous distances. A super cheap (relatively) satellite mesh network would be just the thing to handle Earth to Mars communications. Getting out of left field here but could imagine the whole Solar System dotted with these. Add a few sensors to each satellite and you could start detectin…

One of the big problems with solar-system wide internet is latency. Various protocols assume that there is some upper bound on latency, IP itself assumes that end-to-end latency is less than about 4 minutes (which is'n true for mars at least half of the time), with typical TCP/IP stack implementations requiring significantly less (5 seconds seems to be common requirement for TCP to meaningfully work, 15 seconds is quoted in RFC 791), things like SSL/TLS are latency sensitive enough that multi-hop terrestrial wireless connections can be a problem.

Even when all these technical problems are solved (eg. by replacing the whole IPv4/6 with something completely different) there still remains the problem of the user experience completely changing.

If it's in a sun-synchronous orbit when it is crossing the equator at midnight local time, then it will also cross the equator at midday local time on the other side of the world.

We have weather satellites in this exact orbit right now.

I'd hardly call white nationalism fringe, it's self evidently been here a long time although in the daily discourse it's been ignored, or wished it wasn't as overt as it is. Well, this election showed otherwise. But that is not the only factor. There are probably a dozen stewing issues and Trump managed to ride the coat tails of quite a few of them, not least of which is some people who didn't want Trump president co…

I don't know if it was necessarily that they "couldn't be bothered to show up and vote". My father decided not to vote on the grounds that he couldn't justify voting for either major candidate, and many other people who voted for Obama in the previous election cycle probably felt the same way.

Man, you have to tip your hat to Elon Musk and his teams. They manage to consistently up the scales - its almost like accelerating towards future!

The guys a freak. He's about the only optimistic thing going on at the moment, it seems.

No kidding, South Park's episode this week kind of pointed that out.

I'd absolutely call it fringe. It has a very tiny base of support. It is also on the political extreme - far to the right of the mainstream.

What is the difference between "couldn't justify" and "couldn't be bothered to show up"? Sounds like they just want to shift the blame to the candidates rather than themselves and their own inaction. If they genuinely think both candidates are equally fit, then not voting makes sense. If they genuinely think both candidates are equally unfit, then voting isn't enough, they have to become politically active to convince people to vote for a 3rd candidate. Merely voting for a 3rd candidate without creating ground swell is likewise almost always, 9 times out of 10, punished by the American political system.

Most likely if we had compulsory voting in this country, most of the plurality, who did not show up to vote, would not have voted for Trump. It may have been a scant amount, but very clearly the more eligible voters vote, it favors Democrat candidates.
