This was good. It's good to be reminded of the complexity of things we might overlook.

However the answer to any question around why something is expensive or not is economics, specifically supply and demand, marketing and distribution channels, and barriers to entry.

This is the technology sector. We have made a cottage industry out of taking things that used to be at the maximum level of complexity and turning them into household items. You could write a similar article about how web servers work -- there's an amazing amount of complexity in there, but we've commoditized all of it. Ultrasound tech will follow the same trajectory, although I have no idea how long that will take. In addition, ultrasound providers are marketing towards large, rich, healtchare providers who are operating in a tightly-regulated market. If I had a $1,000 ultrasound that only worked for a year, was quirky, might scald me or my patient, but was good for quick diangoses in the field in third-world countries? It might be all I would need. There is no universal "ultrasound" device that has to meet a ton of specs. That's just the way the market is configured currently.

Good article. Lots of cool stuff in there.

Any examples of pre-IPO companies handing out RSUs? I've seen posts about that on HN but it doesn't seem to be proven in the field. I've read that FICA taxes may actually be due on vest with RSUs, so either the employee pays or the cash-strapped pre-IPO startup spends cash on that, both of which are dumb when there are fully tax-deferred instruments available.

A smaller delta fix here would be to convert ISOs to NSOs with a very long exercise period (10 years) so you don't have to pay taxes until you can sell to cover the tax. I can think of several companies doing that now e.g. Pinterest.
The point of Amazon Go is instant gratification. The point of this is not carrying stuff to your house. Cool troll, but they should be careful of the false sense of superiority. Perhaps they could hire some Nokia and BlackBerry execs to explain the concept to them.

Quite. My recently acquired particular piece of paper puts it beyond any shred of doubt, objectively, but it's only recently I've really acknowledged it. I suspect this has been immensely annoying for people around me.

Yes! A related symptom for me was assuming that people who were good at stuff I'd never bothered to learn were a lot smarter than me.

It happened so many times throughout human history, that it's really foolish to reject. People with their own goals burned, raped, murdered. Maybe superintelligence will build its own civilization, and to suppress remorse will put people in reservations.
RUSSIAN HACKING – CIA director warning against in-kind retaliation by the US
I distinguish between consciousness and self-consciousness, but as to your question, I don't think it matters at all in what form self consciousness takes place, and the moral thing to do when something appears to be self-conscious is to treat it with the same kindness you would expect for yourself (unless it is obvious that this something is a clear and present danger). I can totally see how from a moral perspective a human should be put on trial and imprisoned for killing a sentient "machine" - though unfortunately, looking at how as a society we treat animals and many times look the other way at mass cruelty to our own kind, I'm not really sure I'd mind a super-intelligence (and perhaps as a result also benevolent) ruling us instead of the other way around.

Of course, there's the possibility that a super-intelligence would not be able to break through the human egocentric limitations that may have been built into it by its human creators, and in that case, we're screwed...

I'm not sure if this is meant to be funny somehow, or taken seriously, but the series of strawmans as arguments, eg. referencing some american sitcom as an example to a phenomen is pretty weak. It is sad, because I can agree with many ideas, but the flawed reasoning is not convincing for someone critical, and wastes those arguments...

Although the read is ovarall interresting, but I find the style and arguments sub par, too american for my taste.

If we were to do something kooky and nutty like abandon centralized large corporate offices as our primary places of work, and instead the majority of us worked from home, that would result in many people spending several hour a day in their local neighborhood rather than sitting in their car. I expect local communities would be revitalized simply by default because people would finally be PRESENT instead of commuting and spending the majority of their waking hours far away from their local community. Just another way that the death of our antiquated 'way of work' that was optimal for manufacturing and assembly lines but downright ludicrous now will benefit everyone. Well, except for middle managers. They'll mostly be automated out of a job. Have to get their heart attacks the old fashioned way I guess.

> Elite isn't about the quality of the instruction.

If you read the article, I think the author would disagree, as he refers to Yale and Columbia, not himself, as an elite education.

Here's a thought experiment. If Harvard's professors were swapped out for high school teachers, "elite" students would be less inclined to attend, and over several years, the quality of students at Harvard would almost certainly drop.

Conversely, if someone created a university with all the world's most renowned lecturers, in several years, "elite" students would likely be yearning to attend.

And I'm not clear on what you mean by "democratic elite." There would still be elite students. Two things would be different:

1) Their designation could be determined by cleaner data than was possible in a pre-MOOC world. In the current world, there are few clean baselines on which to evaluate students from different high schools, for example, which is one of the main reasons standardized tests like the SAT exist.

2) If we assume that a better lecturer will help increase a student's knowledge, regardless of the student's quality, then every student's knowledge could be maximized in the post-MOOC world, not just the small fraction that are able to gain entry to elite institutions.
Even if you just consider the film classics based on his books (The Shawshank Redemption, The Green Mile, The Shining), he'll have staying power as people will find his books through the films.

What I have not seen is the explanation about transferring the data normalization parameters. Say you apply the contrast normalization to the images you use to train the first network.

Mmm, I remember mishaps with updating but those were quite some time ago.

I've been on 6 EU flights since the US ban went into place. 2 were BA, 1 was Norwegian, 2 were flybe and 1 was wizzair. However, none of them said we could not have them on board.. but we were told that they must be off, and not charging during the flight. One said that if we dropped the phone and couldn't retrieve it, we were to notify flightcrew as a matter of urgency.

Speaking about exact itineraries, it is a very common practice. For instance, for almost all ex-USSR, travelling to the "Western World", you have to provide the same exact route of you with days, reservations and tickets. Some countries don't care, but some, like Germany or UK, are very strict about it, which is a big pain in the heck, at least for lazy people like me – it is like the biggest problem for me even to visit UK, because I don't like such strict decisions!
>Have you ever programmed any piece of software that suddenly implemented features of its own?

I'm not sure what particular fear mongers you're talking about, but Bostrom and the like are talking about software that's specifically made to change and improve itself on a fundamental level.
In order for such a thing to work, 2 things would have to be true: First, those able to make the decisions to do such things would need to be willing to listen to the AI. Second, the AI would need to be saying things that we do not already know would help. Because if it's just saying things like "reduce economic disparity to lower the crime rate" and "increase autonomy of adolescents" and similar that we have had the research for decades to show are effective, well, why would those able to change things listen? They ignore research, they're not going to listen to an AI if it's saying things that conflict with their worldview that produced the problems in the first place...
Money is just a trading medium. There are an awful lot of things that it can be traded for so there's an awful lot of people with different wants and values where "acquire money" is a necessary step. Those things can then make other things, that money couldn't buy directly, easier.
I didn’t say these were “mistakes”, only that I disagree with the pedagogical choices made.

I don’t think we should start with something entirely abstract. Indeed, I want to start with something much more concrete: physical pictures of vectors as arrows, and a collection of concrete geometry problems to solve. If we later want to layer in a coordinate system (e.g. because it helps us solve one of our listed problems), we can draw several possible sets of coordinates over the top of our pictures, and think about how the computations in each coordinate system change while the underlying vector arithmetic stays the same.

Coordinates are an abstraction layered on top of vector spaces, and it is difficult for many students to understand the difference between the system or model being studied and the arbitrary details of one representation. I think focusing on coordinates narrows students viewpoint and leads them to a more rote/computational and less conceptual understanding. To the point that e.g. many undergraduate physics majors have difficulty with tests of basic competence about vector concepts, despite needing to solve a variety of hard computational problems.

Indeed, this specific failing of conventional formalisms is one of the primary reasons to switch to geometric algebra as a modeling tool in the first place.

It’s like trying to teach someone to play chess by looking at “algebraic notation” instead of starting by looking at a board and moving physical pieces around, or teaching someone phonology of a new language by looking at prose descriptions in their original language and static diagrams of a mouth, instead of starting by just directly listening to the sounds.

New languages, systems, abstractions, etc. are best learned through (at least some amount of) immersion in the mode of thinking/communication of the language, not purely through formal analysis using external tools. The presentation in the OP leads me to believe that the author (like myself, to be honest) is not actually fluent with thinking about geometric algebra concepts / tools, but is treating them like a novice second-language learner.

(Sorry if that sounds harsh. I’d love to buy the blog post author a coffee or beer if he’s ever in San Francisco.)
Here's an interesting take on the development of Twitter by Jonathan Blow.

Immigration officials have already demanded that people enter their phone's passcode so that they can access its contents, I don't see why social media accounts would be any different.

He probably scratched his own itch.
Your argument would have been a lot stronger this time last year. Brexit and the Philippines are notable examples of some fairly sociopathic political behaviour that fairly closely followed on-record comments. What happens next year will be the exciting part.
> If you just made a new effective ultrasound system that passes the FDA, why would you sell it for a lower price when you also can make more money?

Because you have an ideological desire to make ultrasound available in the developing world.

EDIT: There are a number of large, wealthy, organisations that have this desire - to improve the quality and availability of medical stuff in the developing world.

They have enough clout (and money) to bring a cheaper device in.
Thanks for leaving a comment Sam. Glad to hear the upgrade went smooth and people are happy. People that experience problems are more likely to let us know about it so we greatly appreciate your comment.
> - They had a reserve of good ideas and used them up faster than they could generate new ones

I think the quality and complexity of the ideas also matters, perhaps more even than quantity. Some of my favorite 'creators' who become better over time tend to focus on essentially the same thing over and over again (more than others, it seems). But their later works are richer and better and developments from earlier works.
I doubt there's an agenda to push Apple products but the sane approach is just to insist all phones are switched off as you say.

If we're completely honest, with little effort any LiPo can be turned into a threat. Puncture a sufficiently large LiPo, throw it in the toilet bin and go back to your seat. With a phone, laptop and camera - all with spare batteries it's conceivable that you could cause some serious damage.

It's impossible to remove all risks on an aircraft - they will always be there. It would be better to have better handling - i.e. a large fire proof bag and a bucket of sand. Inevitably this will end up happening regardless of what checks they put in place. Fire extinguishers simply don't cut it with LiPos and I doubt their staff even know that.

I imagine that would happen, but as soon as the size of their economy was large enough to attract the notice of the Hyperclass, or even just one member, it would be completely undercut by them. I don't know what an equilibrium state would look like.
I always retell this story when this subject comes up:

When I was 17 in 1989 I was desperate for a job in 'computers' as it was all I knew, I was damn good at programming etc, but had the usual experience trap - no experience equalled no job.

Being naive I paid attention to one of those adverts in the back of the weekend newspapers. I don't know if they were a UK only thing but they had a puzzle and stated that if you could solve it within 1/2 hour you could be a member of Mensa, which if anybody doesn't know is a club for those with a high IQ.

I completed the puzzle then got posted back another one, if I could complete this within an hour I would be invited back to a proper, invigilated exam. Passed both, paid my dues and became a member of the clever club, along with people at the time like Sir Clive Sinclair. My mum was very proud.

I went to one of their meetups shortly afterwards in a bad cheap suit hoping to meet some other clever person who'd recognise my skills and give me a big wad of cash and a job.

It didn't turn out that way. There were 30~ men at one side of the club all staring at their drinks, with 3 woman at the other side about 20 metres away keeping away from the fellas. One woman came in by mistake to the side with the men at which point they all swarmed her. The only topic of conversation they had went like:

"What's your IQ?"

"x"

"oh, mines <x+10>"

When it came to IQ these people were the top of the pile, with social interaction however they were abjectly hopeless. They'd be able to build you a nuclear bomb, but they wouldn't be able to sell or explain it, or even go to the shop to buy the parts for it.

This encounter came at a good point for me - it made me relax a bit about being 'clever', and showed the importance of other indicators. I let my membership lapse and wince when I occasionally see 'member of Mensa' on a CV.

Some context:

https://www.theguardian.com/world/2016/dec/21/adam-saleh-del...

"A YouTube star known for filming elaborate hoaxes was escorted off a Delta flight on Wednesday morning after he claimed that other passengers complained when they heard him speaking in Arabic.

Adam Saleh, a 23-year-old YouTube star from New York, posted multiple videos to Twitter and Periscope on Tuesday, showing himself being escorted from a plane by Delta flight attendants.

Saleh said in the videos that after passengers heard him speaking Arabic, they “felt uncomfortable” and called flight attendants. However, while it is clear that he was removed from the flight at London’s Heathrow airport, the circumstances leading up to the video – retweeted more than 644,000 times – are not known and cannot be verified.

Saleh has created videos in the past that involved staged scenes on airplanes and with actors playing authority figures."

1. Shipping is good. 3,5 years may seem bad, but it's much better than never, which is probably what this guy is celebrating. Having worked in big tech companies, where you basically get nothing done because of broken process and politics, I get why he is happy about this

2. lol, 3,5 years is still ridiculously slow. Sure there can be technical difficulties, sure it can be a side project, but that's a really bloody long time, companies are built and make dozens of millions in that time. I could probably build a faster twitter with a good team in that time.

It's hard to see which is the stance here, I'm happy for the guy for shipping, but it makes me kind of lol. Our industry is stupid sometimes.
