Even then... It's been my experience that assuming you're not an idiot (granted that's a bold assumption since you didn't study until the night before) and showed up to lectures or at least know a little about the material, you'll often have better chances reasoning out the questions in a less sleep deprived state.

I'm out of mod points, but that's a actually pretty insightful.

I'd suspect that the first AIs we'd see (if sci-fi style AIs even become a thing, I don't think they will but that's a different argument) would be to do things like predict markets and aid in complex decision making. If AIs did decide to "take over", I would suspect that it would come in the form of giving humans advice, and then humans willingly following that advice because they know that the AI is quite smart and it'll make things work out well in the long run.

Eventually humans might technologically regress (or AIs might just become smart to the point we can't comprehend their thought processes anymore) that the AIs become the future analog of old time prophets telling people when to plant their crops. I doubt that an AI would decide to kill all the humans, thought they might end up using humans as pawns to kill each other. Either for population reduction or maybe to take out or defend against a competing AI or some reason completely incomprehensible to us. By that point humans may willingly go and do it in the same way that dogs have been used for similar tasks.

I've seen these guys before at maker faire. It's a neat idea, but I never really understood what was so special about it compared to just downloading a smartphone app or internet or (*gasp*) maybe even reading up on how to do the math and figuring out where it is on your own.

The problem is that there's only so much you can do to a signal to amplify it before there's no signal left.

With a current gen headset, if you were to turn off the 60hz notch filter, the signal it would be picking up from the power lines would drown out the brain signals by several orders of magnitude. Even someone waving their hand over top of your head while you wear one will cause enough interference to blot out the sorts of signals the brain produces. On top of that, those signals that we can pick up are extremely broad, created by millions of neurons firing in sequence. Unless it becomes legal to plant wires in peoples heads that can detect the actions of single neurons, or we develop some kind of wearable FMRI, the kind of things that article is worried about are so far ahead as to be in the territory of asking how we should regulate flying cars.

EEG technology is akin to telling what state a computer is on by opening up the case and pointing some IR thermometers at different components and measuring the temperature. I could tell if you're doing something graphically intensive vs CPU intensive vs memory intensive, and maybe make some inferences based on the time of day and previous states but that's it. It doesn't matter how much more sensitive you make an IR thermometer, it's not going to give me any more detailed information than a vague idea of what bits are being used more than others.

Because no one cares if a computer flies around the world. They need to see a human put their life in danger for it to be interesting.

Definitely a click-bait headline. They have enough trouble getting the accuracy and resolution required to tell those sorts of things with medical grade EEGs, let alone a consumer grade headset.

But but but.... if you haven't done anything wrong, then you've got nothing to hide from their wiretaps!!11~

Well.. if you say so I guess.

Personally I was going to chalk it up to some kind of art project where the artist was attempting to spell out letters in a different language using random electrical components as the medium.

I just drop that carrier and find anoth... oh wait...

Thanks obamacare!

Key point here: no consequences for both the aggressor and the victim.

If I do something mean to someone in a game, it takes place in that game. As soon as everyone quits playing, actions taken ingame cease to matter since it was just a game.

Societal norms are just rules that have been made up by society. Games have their own norms made up by the players. Different societies will often have norms so different that they consider each other to be evil. Applying a real life societies values to a game societies values is an apples to oranges comparison.

And then one day they radically change their hair stye and wear a new outfit, causing hilarity to ensue.

Star Wars prequels.

It'll be hilarious if it turns out that she was in the placebo group.

Another thing the OP might be interested in is P300 speller. It scans across a grid of letters and watches for the P300 response to fire off when your letter is highlighted.

We actually worked with an emotiv headset in a class on brain interfaces I took last semester. It's a cool concept, but it's no more than an expensive toy sold by a bunch of flashy marketeers.

The build quality on the headset is terrible. I bought the consumer edition about a year ago because it looked interesting. When I first got it, the front right sensor (I believe that's P2 in the 10 20 system) was broken right out of the box and it took 2 months from me putting in a ticket to getting the repaired headset back. When I finally got it back, the detection was disappointing compared to what they showed in their marketing material. Then when I took it out again for this class, after a few weeks the plastic bits on the removable part of the electrode that lock it to the sensor arm all started to break.

The one the school bought for the class was a research edition. Within a week of use, the front right sensor started to die the same as mine, and it was completely dead after 2 weeks. Then the plastic locking bits on the removable part of the electrode also started to go. The icing on the cake was when someone was putting it on their head as they and everyone else had normally been doing for half the semester and it literally snapped in two.

Physical complaints aside, the company is shady as hell. In some of their material, they show a video of a paraplegic guy wearing the headset and moving a mouse pointer around on his screen and typeing. It would have been great if they mentioned that he was just tilting his head slightly to use the gyro embedded in the back of the headset, and then blinking his eyes to click. Instead they fell just shy of false advertising by leaving the viewer with the implication that the guy was moving the mouse around with his brain.

Another hugely annoying thing is that there's literally no difference between the research edition and the consumer edition. There was actually some worry of mixing up my consumer one with the schools research one. The only thing that makes the research edition the research edition is the fact that it has firmware which doesn't scramble the raw data so that they can slap a $750 price tag on it rather than the 300 the consumer edition costs. The software licensing is also obnoxious in that they have so many different versions of things, and their documentation of the APIs is quite bad.
