8k won't be ready for anything any time soon. HDMI 2.0 doesn't even support 8k 30Hz, and few TVs have Displayport. 4k Blurays are taking their time arriving to market, and 50GB arguably won't be enough for 8k without a codec upgrade which would itself require a new disc player. What portion of existing bluray players have old HDMI ports or processors that can't handle 4k content? It's not like 4k TVs are high-margin items anymore -- I saw a nice 50" one at Walmart for $699 a few weeks ago, and there were cheaper ones online. The price has hit rock bottom before there's even the demand for them. Unlike 4k cameras, there are only a couple prototypes of 8k cameras, so almost all content will be rendered CG for a while.

I'd read countless arguments on Slashdot that human eyes can't discern resolution higher than 1080p in a 50" TV over 10 feet or so, before I actually watched a demo 4k TV running 4k content, for about 15 minutes. If you have a 50" TV in your bedroom, 5 feet away from where you're sitting, you can definitely notice a huge improvement in detail. I stepped about 15 feet away and in most scenes it was still usually an obvious, substantial improvement over 1080p.
An electronics retailer in Europe held a contest, setting a cordon that people had to stay behind, more than 10 feet away from two televisions, and were asked which was the 4k tv and which was the 1080p. 98% of people correctly guessed which was which. Maybe people asked others who cheated, but it suggests that "most people can't tell" is bullshit. I seem to recall when the Apple retina display claims first came out, a scientist mentioned that humans' actual acuity was about 50% better than what Apple was claiming. It's also worth noting that while a single still retina image may be at a certain DPI, there are psychovisual effects (like depth perception) that can improve the resolution inside the brain, beyond what one retina picks up at one time. The eyes also saccade all the time, which I seem to recall can be interpolated to improve resolution.

They haven't announced an Assassin's Creed game for next year, yet. Hopefully they'll learn from their mistake, and delay it until fall 2016. That'd give them time to fix up the performance issues and myriad glitches with the updated engine. Maybe at the same time they'll rethink the idea of the microtransaction-unlocked chests.

All laws involve giving up freedom to do a certain thing, usually in exchange for security or safety for the society. Other laws, particularly regulations, ensure justice via making society more fair; for example the USA's Civil Rights Act prohibits a variety of forms of discrimination. The problem is that our overlords use propaganda to convince the plebes that a broad selectively-enforced law is necessary when a narrow strictly-enforced law would lead to more security for the society. Being secure in your belief that you won't be imprisoned falsely, or under a law that wasn't intended or reasonable to apply to your situation, is also an important aspect of society's security.

Nintendo took the legally safe option by recommending children under 7 not use the 3DS' 3d mode, although research wasn't conclusive that it could cause Lazy Eye. Palmer Luckey (CEO of Oculus) actually directly responded to a query about this. I seem to recall him saying that it could eventually be made safe for children. The 3DS uses an adjustable virtual inter-pupillary distance (IPD) which is most likely set different from your real IPD. In contrast, the Oculus Rift is calibrated to use your real IPD, and your eyes focus at infinity while using it. Given that, the Rift should be far less likely to cause Strabismus.

There's been little point in developing those technologies thus far, though. Until VR software exists where the programmers intend to adopt technologies which maximize the immersion of the player, and players are in a mindset where they want their immersion to be maximized, it won't happen. Haptics and motion tech are reasonably far along, sound is nearly there, taste is pretty much there, but smell is going to be trouble with current tech though. According to many people who have used the Rift, it subjectively 'feels' like you're in there, even if some senses contradict the world presented.

It was recently found that when the FCC (or some other US federal govt. agency) has a request for comments, they're only compelled to seriously consider the in-depth, intelligent comments. In practice, this means that form-letters done via the EFF website etc. are tossed out, while lawyer-produced walls of text that read like Congressional legal pronouncements get serious consideration. Almost always, the latter are produced by big businesses with lots of money to spend on lawyers to ensure the decision goes in the direction of greater profits for themselves.

The only way to undermine this is for organizations like the EFF, and individuals, to gather and present as much easily-digestible data as possible and edit and refine their message until it's intelligible and palatable to a politician. Mindless ranting is immediately dismissed as uninformed. Probably only a dozen or so of these 1.7 million messages will actually be read by a decision-maker.

Fax is the best medium to contact your agencies with, as it tends to be printed and read by a human, rather than a keyword-search-delete-all like can be done for email ("delete all emails containing superlatives"). Also, 1.7 million sounds alot bigger when pushcarts full of paper can be wheeled into their office, rather than the messages easily fitting on a disc or flash drive. I presume they don't tend to auto-OCR faxes.
