Before I ever entered I.T. professionally 20 years ago, people had been claiming the impending death of magnetic tape for more than a decade. at least, yet it is still with us today. Sure, the round-wheel tape is more-or-less gone, but tape is still going strong.
Similarly, SSD's are not going to completely replace mechanical storage any time soon, if only because as solid-state memory improves, so will mechanical devices continue to do, and they will almost certainly have a place in modern computing for many years yet to come, barring some as-yet completely unforeseen revolution in materials science lowering materials and production costs while raising quality and value to thresholds well beyond anything currently predicted. Then again, the same advance (such as room-temperature superconductors) could have wide-ranging positive impacts on both technologies, increasing memory operation speeds in SSD's while eliminating the mechanical bearing from HDD's and providing similar performance increases.
After all, I'm pretty sure that if I dig back far enough, I can find at least one thread - quite possibly one I made substantially similar comments in - on this very site from ~15 years ago with someone saying much the same thing about how optical (or magneto-optical) is going to make tape/mechanical-drives obsolete. Now we know optical disks have a life-span before they degrade, making them useless for long-term archival storage, and I couldn't tell you when the last time I saw a mini-disc was.
The key is the specific frequencies (notice the plurality) of light reflected. The human cornea, like a camera lens, has a rather unique and readily identifiable reflected spectroscopy, and both are easily differentiated from the other.
Seriously, not an NP-hard problem. As is usual, people are trying to make it out as more difficult than it actually is.
Besides, if he does the footwork and engineering on his customer's dime, he (and perhaps the customer, as a partner in a joint venture) could come out of it with a product they can market and sell to other similar bus operators, theaters, etc.
None of the tech I outlined is rare, odd, or terribly expensive (excepting LIDAR units, at about $5k each), and can be done entirely with COTS hardware and some customized programming that would only have to be built on top of programming that has already been done in this field. In fact, the PS3EYE or Kinect already has most of the capability needed.
Honestly, I've seen homebrewers do much more complex things (including code), such as the home-built, automated air-hockey table built by a father for his daughter, which not only has to identify the puck, but then do loads of computational math to determine angles, speeds and force loads: what I initially described in my original post would almost be child's play by comparison.
You might also be able to accomplish this more easily, without having to map your "legitimate" cameras, by mounting said cams behind some sort of cover that would obscure their lenses from being sensed by the anti-camera-camera by dint of the covers by altering/filtering the frequency of the light reflected by the lens.
If you wanted to try something somewhat more COTS than trying to build and program a rig to do this (though a lot of the basic frameworks for things like high-speed visual target acquisition by sensing cameras and pattern recognition suites are already "out there", if you're willing to dig for them or do some legwork contacting the developers), you might try a LIDAR unit of some variety, though you'll almost certainly still have to do some modifications. I have no idea, however, whether or not the light freq's used by common LIDAR units will interfere with a camera the way more traditional lasers do.
And anyone who thinks electromagnetic tape is "dead" is naive or just ignorant. People have been predicting the death of tape for decades, and it's no more true today than it was in the 70's. Modern EM tape is typically rated for 15 to 30 years of retention, and as long as it is not over-exposed to moisture during storage, it has proven to be able to last that long: otherwise, the manufacturers would be out of business because the Fortune 500 and S&P 500 companies - the majority of whom backup to tape and send it off-site - would have sued them to extinction.
On the other hand, according to archives.gov:
"CD/DVD experiential life expectancy is 2 to 5 years even though published life expectancies are often cited as 10 years, 25 years, or longer. However, a variety of factors discussed in the sources cited in FAQ 15, below, may result in a much shorter life span for CDs/DVDs."
I'm not going to help edit, because I have little or no use for what common consensus is. I'm interested in fact and truth, not public opinion.
Q.E.D., you are, then, part of problem, and have no right to whine or complain because you can't be bothered to help fix it. Go use Britannica, then... which was found as late as 2005 to be generally no more accurate or reliable than the Wikipedia, with broadly similar error levels. Or how about Nature, who themselves state that retractions in their journal have risen ten-fold in the last decade, even while the number of submissions has only increased 50%. Because they're utterly reliable and the peer-review process can't be subverted, right? How many times was that now-discredited MMR vaccination study reprinted as golden gospel, for how many years? How many times has an outsider to academia and private industry journals made a stunning breakthrough that might have come sooner if only some critical bit information had been publicly available, instead of buried in a back-issue of a private publication? How many millions or billions of dollars have been wasted re-reviewing science that was based on something once taken for truth by the major journal in its field, only to later be proven false?
Like any other information source, Wikipedia will only be as correct and factual as the people contributing to it can muster, and without the help of subject matter experts determined to make sure the truth is told, it will be bottomed on the knowledge available; the Wikipedia, however, has a much larger pool of knowledge and experience available to it - if people choose to take part - than any journal or trade magazine. If people who have and can source/prove/demonstrate the facts on developing, highly technical or contentious subjects would commit to contributing as much to making sure the Wikipedia is accurate as they do to closed academic journals that no one but academics ever read, then we'd be in a much better place, with a better educated populace, as a result of access to true and up-to-date information, as opposed to last year's conjecture and common wisdom. For that matter, how many times did Britannica, for example, choose not to cover a subject - or not cover one in as much detail as was available - in order to conform to demands of governments and corporations, which do not affect the Wikipedia? Somehow I doubt they'd have ever penned more than a footnote - much less an entire article - about FOGBANK... oh wait, look, not even a footnote.
What would lead you to believe that a group of 10 supposed experts in a field editing at a journal are infallible and never make mistakes, but 100 or 1000 people - some of whom may also be just as expert, or even the same experts - cannot come just as close to truth and fact? What makes you think the scientific and history communities have more than a few dozen things they can all settle on as incontrovertible, accepted fact that no one can reasonably debate? Let me guess, you're the same anonymous coward that was arguing a few weeks ago that nobody can make money on making open-source software and that all FOSS sucks because only large corporations get anything done?
How about show me an established article in the Wikipedia - and not a revision someone is vandalizing - that is purporting something to be "fact" that is provably just "public opinion", and wrong at that... and I'll show you an article you should have just fixed, assuming you can demonstrate said fact from a reliable, neutral source. Otherwise, I'm going to have to conclude you're just mad because someone reverted your edits on an article when you tried to assert a claim on a debatable subject and couldn't back it up.
I'd also really like to see this always-accurate-and-reliable source of information you seem to be purporting exists. You know, the one you can always count on absolutely to be so factually complete that you never need to cross-reference another source of information and research - as any good science or research demands - because it's all-inclusive and has settled all questions of science and history... oh wait, that doesn't exist. The Wikipedia is meant to be one more avenue TO research, not OF it. It contains information and references, and you're supposed to do your OWN research, not use the Wikipedia directly as a source for it. If you can't be bothered to flex your intellectual muscles and judge how accurate the information presented is for yourself, and then choose whether or not the information is reliable enough to warrant further investigation on your own, once again, the failing is yours, not the Wikipedia's: no one else can help you if you're too intellectually lazy to do research, and no source of information is reliable enough to simply spoon-feed you without any chance of error. If that's what you want, I suggest you find religion.
No, the answer is not for a bunch of people to elect another bunch of people via popularity contest to exercise power over everybody else, especially including the people who didn't want the people who got elected in the first place.
The better answer would be for people like yourself to, instead of throwing their hands in the air and blaming everybody but themselves for the problem, to actually get involved in efforts to combat those doing wrong, such as taking part in Wikipedia's anti-vandalism process, as opposed to just crying about evil corporations, etc.
Remember, governments aren't interested in people, they're interested in furthering themselves and their own authority. No matter the intentions they start with, democracies evolve into tyrannies nearly without fail: Plato pretty well nailed it with the Five Regimes. It's one thing when participation in a body with a government is voluntary, but when you propose to place everyone under your "protection", whether they want it or not, you're a mob with mafioso leanings at best.
If this is an issue of genuine concern to the Wikimedia Foundation and their leadership, they can alter their policies to combat it. I don't propose to know how best or even if they should do so, but they have the ability to respond as they see fit, and there are undoubtedly options they could pursue if the threat is great enough. Let them and their governing body choose whether to subject themselves to some other governing body or shielding organization, if they wish to abrogate their own control and responsibility, but to suggest everybody should be de facto subject to another group of people making decisions for nearly everyone else based on principles they may not share is how you get the mess we have with most of the world governments today.
Nice fallacy, namely your assertion that commercial vendors actually do any work, especially after-the-fact... you know, like all the updates MS has made to the registry editor over the years, or the extensive CLI functionality, and let us not forget their impressively powerful and flexible search/scheduling options they built into Outlook.
You keep using that word ("you")... but I do not think it means what you think it means. I believe the word you're looking for is "I", because if your assertion were true, Ubuntu, CentOS, Debian, FreeBSD and many others wouldn't exist - or wouldn't exist as they do today - with a huge amount of software being continuously developed by people who are happy to keep doing it so they have the tools they want/need to do what they want to do.
Maybe *you* kept getting ripped off because you were doing it wrong. Meanwhile, I'm going to go have drinks with my buddies from Redhat who get paid perfectly well.
Leicester is correctly pronounced "lay-ses-ter".
No it isn't. It's pronounced "les-ter".

In any event, there has never been even a hint of a reason to believe that PGI has any interest in learning from the successes and failures of anyone else, that they have any interest in listening to or heeding the demands of the community - without whom there is no reason for their game to exist, and so this should be their highest priority - or has any desire to do anything but milk the Mechwarrior property - that they muscled a large team of devoted volunteer developers out of making a free game in because they were intimidated by their ability to produce high-quality work for free - of all the money they can.
As for Garnaralf's diatribe above:
The fact that it's selling means nothing. It's the first commercial Mechwarrior game - a series with hundreds of novels to its credit and a fan base spanning 30 years - since the atrocity that was MechAssault (aka MechAssFault or MechsAsFail) so it was unquestionably going to attract a large number of downloads (which means nothing. I presume they count my player account towards their playerbase, and I've never actually done anything more than register my user name) and user registrations. Making a game free to play also means nothing, and has no reflection on the goodness of the company making it: it's a viable business model, nothing more.
The LONGSTANDING Mechwarrior community (almost 30 years old now) has by and large shown nothing but hate and derision for 3rd Person Views, at the very least since Mechwarrior IV, where it was well known to be a game ruiner: the MWLL team patently refused to consider it; 90% of MWO's players, by PGI's own polls, said they did not want a 3rd Person View, and made it clear that if there was to be such a mode, they did not want to play in the same match as other people using it due to the fact that it breaks immersion, changes the tactical mechanic, and provides an unfair advantage to those using it over those who don't. So what did PGI do? Ignore them, implement it anyway, then lied about separating 1st/3rd person players into different matches, repeatedly: that's not the sign of a "good company". I'm not sure what else you're basing your assessment on besides the fact that they make a game of which you are clearly a player, but if anyone needs to put down the crack pipe and do a more thorough investigation of reality, it's probably you.
Where was PGI's social consciousness BEFORE a player's daughter passed from cancer that obviously resulted in a social media campaign that they elected to pile on to to improve their image? You *do* realize that they get a HUGE tax break for that, right? The amount of money a game earns for a charity by pulling on players heartstrings and offering them up something that took almost no effort or time on their part (did I mention I'm a texture artist with significant CryEngine experience as well as friends and professional contacts at CryTek? There is, maybe 20 minutes of texture work, *tops*, on that Jenner, and 5 minutes of XML to edit the weapons config, plus 10 minutes to commit it to the build) in return for that charity donation is also not an indicator of a company's goodness: how much of their own profits did they donate? How much did the owner and executive officers pony up out of their own pockets? How much is the company going to be donating - regardless of charities - to cancer prevention every year from now on?
No, without going into excessive detail or listing my qualifications (I know I have them, I was there, I was involved), I can safely say I know enough about the issue, the company, and the arena in question to know that PGI is not, in fact, a good company, which is why I, as someone who has been playing Battletech since 1989, who has owned every prior Battletech-related video game, and has even worked as a developer on a Mechwarrior title, absolutely refuses to install their game on my computer and lend them any semblance of support or approval, for their game, it's design, or their company.
