I agree with you on many points but I think technology has been moving in many ways to solve the problems.

On the issue of actual neurons vs ANN, I think issue 1 is probably going to be remedied by advances in memristors. The biggest issue I've seen in most ANNs has been the fact that the entire system is simulated with a single processor having to calculate every neuron, but small bunches of memristors could eventually do this for us and we'll be closer to an actual brain. See: http://phys.org/news/2015-05-b...

The issue of internal biology in neurons is a big unknown though. We know that cell biology has a big affect on cognitive ability. The real question though is how much of an affect it has on the actual processing capabilities. While many people are interested in human level intelligence, I think just being able to reach human level signal processing might bring us half way to where we need to be. In this case, the structure of the neural nets is probably more important than the careful interplay of cellular biology. Given a normal human, we can determine baselines for how different neural structures fire and then mimic those.

Amusingly enough, the toll roads in Japan use a fast access card called ETC. I believe you can get an ETC card that you can charge up somehow, but its difficult to get. Almost every ETC card has to be linked directly to a credit card (I got mine when I signed up with Rakuten for a credit card).

I think the reason has to do with the fact that the express highways in Japan are incredibly expensive. (10-20 mile span of road could cost you $30-50). Going from Osaka to Tokyo via the express highway would cost you about $200 in tolls (no joke!).

I'm not really talking about the card, but the mobile payment systems basically piggy backed off that model.

The Suica phone app for instance, I could link my credit card to it and charge up the "virtual card" on it at any moment. There was also an option to link it to your bank account I think. Edy has a similar service if I remember correctly.

Cards are still in wide use but I think by the time I get back to Japan in 3-5 years; I'll probably be seeing far more people using their phones instead of a card.

I've lived in Japan and used the cellphone payment system. It works quite well now that most places have gotten in line with the correct payment system. A big problem for awhile was that some stores would have one payment system and another wouldn't. The train card linked systems quickly came to dominate though (in Tokyo that was Suica).

The key difference between Japan and the US though, at least from what I've heard, is that in the US they want to tie payments directly to bank accounts or credit cards. In Japan this didn't happen on most payment systems. If you went into a store or paid for a cab with your phone, the money didn't come out of your bank account or credit directly. You would have to charge your electronic payment account with money from your bank account or your credit card first before you could use any money. I like this system because it allowed for a lot better management of funds and avoided potentially using more than you thought you had.

Regardless of what any of the articles say about the decision to do this, I personally believe the reason behind this is because Sony is bleeding money left and right. Sony has been selling off parts of their company for the past year now. It's no secret, Sony has been sinking slowly. They sold their mobile division, they sold their Vaio division, and probably came pretty close to selling their TV division as well, before thinking better of it and simply split it off into a new company. Now they are selling one of their big game studios. If Sony can't find a new market to be successful in, then I wouldn't be surprised to hear about Sony being bought by another company here in the next 3-5 years.

Another angle people need to keep in mind is that Texas is a prime target for a hyperloop in general. Some of the documents put out by the Hyperloop Transportation Technologies group, say that a loop between Dallas, Huston, and Austin would be very profitable. If the test track works then it could entice Texas to let them build a real one.

All this algorithm will accomplish is showing the personality that a person shows to Facebook. The reason why it can "better predict a person's personality than their friends" is because people have different personalities around others. I've known this since high school. I had many friends and when I hung out with some just 1-on-1 they were chill and quiet; probably because that's how I was. But if you got these friends together in the same car or the same house, they suddenly became loud, rambunctious, and prone to doing stupid stuff. This still holds true today. So people have different personalities or faces depending on the people they are around and I'm sure Facebook has its own unique "face" as well.

The sheer number of stars in the Andromeda photo is humbling. While panning through it, the thought struck me that perhaps around one of those stars exists a planet with intelligent life that might also be looking at a high res image of the Milky Way and be thinking the same thing about them.

It might be god from our perspective, but it might be a let down of a god in other ways. Consider this scenario.

300 years in the future we discover some way to simulate an entire universe easily within a computer. So we create one and let it run for billions of years inside the simulation till intelligent sentient life emerges. This life makes great strides, it goes to space, it advances, until one day we look in and decide to "pull one of the beings out." We pull the "mind of the being" out of the simulation and put it in a robotic body. Maybe at first its amazed at everything, we show it the world it lived in and the things we can do to the simulation; and for a short while it calls us god. But eventually the being realizes there are still things about this "outside" world we don't understand, and suddenly it comes to the realization that if I'm from a simulation what if they are too? Are they really god? Is the being on the outside of this outside god? It could be simulations inside simulations to infinity so long as the simulation (B) inside a simulation (A) can be done within the limits of sim A. We know nothing of the physical limitations of the simulation outside the one we are in.

The point is that we can never be sure the being we are talking to is actually "god" in the sense that we tend to think about it in religion and language.

This study is interesting, but I'm way more interested in the affect of conditioning and body temp regulation. I grew up in the US and all of houses/apartments always had good temperature control as well as ceiling fans in rooms. I got use to living in places where if the temperature was above say 70F, there was a fan running, the air in a room was circulating.

When I studied abroad in Japan and then moved there I discovered this wasn't the case and constructed a theory that early life conditions on body temp are 'imprinted' in a way. Japanese tend to let rooms run very hot. In the Summer/Winter rooms and trains are kept at about 28C maybe 30C (possibly higher in the winter), and I always found these miserable and always resulted in me sweating. I always noticed though that most other (Japanese) people never had this problem though, even in a room thats almost as hot as a mid-summer day in the winter, people would have 2-3 layers of clothes on and would be fine. I knew I wasn't alone either because in talking to other westerners living in Japan I learned that many of them had the same issue too. The only reason I've been able to come up with was that it had to do with how they were raised early on and the kind of temp. environment they are use to living in.

So I'd be curious to see if these physical effects in the study aren't something that isn't tuned by early conditioning.

I've participated in some TCS experiments back in college. Unless they discover some new way to do TCS there is no way anyone is ever going to find the technology usable in an entertainment environment. Remember that in order to cause the neurons to discharge magnetically you have to send a strong enough magnetic field through the skull and through a certain amount of liquid. In addition, the field has to be changed constantly as well.

For anyone that has never done TCS, what this effectively results in are constant static discharges on your scalp and this happens at a fairly rapid frequency. Plus, depending on the location of the magnets, the magnets might also be causing muscle neurons to discharge as well, so your face will be constantly twitching. All of this leads to a fairly tiring experience.

do research.

Pondering on singularity AI's, I always thought the biggest hurdle to a full range AI that can advance science faster than we can conceive of it, was the physical limitation. Some research can be pondered on but a lot of research and advances needs to be done in the real world. What good is an AI that can't test out if its theory on a 30% stronger steel that's 50% lighter, is possible?

If you lived in Japan like I have, then you should know the answer to this.

1. Japan values customer service. Having a face be there to control the train or open/close the doors makes the service "friendlier." Also, if they removed the staff and made it automatic the old people would complain.

2. "Its how its always been done so why should we change."
