    You've (perhaps deliberately) misunderstood the argument. In your example, is you/are you, the choice of conjugation of the verb "to be" is based on "you" not "data".

    Incidentally, is it my family IS or my family ARE? Data can be multiple pieces of information even about multiple things, and as a single umbrella name for that information, it would be appropriate to say "the data is..." just like "my family is". Data is information, and we don't say "the information are missing". We say "the information IS missing"...

    The data is all in, and my family entirely agrees with me on this point. (See, data here, multiple pieces of information is treated as a singular noun, just like family.)
    You could also say "The data are ..." Hmm... actually I don't like that one. I came here to make ONE point and ended up taking a side instead. DAMNIT!

    Okay, put me down as "Data IS". NOW... is it DAY-tuh, (first syllable rhymes with LAY) or DAA-tuh? (first syllable rhymes with CAT)?

    I'm in the "rhymes with LAY" camp. So "The DAY-tuh IS..."

    AIs do the jobs humans don't want to do.

    Seriously though... this is fear-mongering about the WRONG damned thing. AIs are not out to steal your jobs. Your BOSS is out to buy something that will do your job without requiring time off to take its little AI kids to soccer practice or whatever.

    What fresh hell will this do to human society? How specifically is this the harbinger of the end-of-days?

    It's not. We have lots of problems, many cited in the story, such as income inequality, etc. But AI isn't doing that any more than the advent of the motorized automobile destroyed society by putting farriers and saddlers, etc., out of work. They just ended up having to get new skills and do new jobs.

    The "cotton 'gin" didn't end society despite automating the weaving of cloth (or whatever a cotton 'gin does,) making (whatever it does) probably about less than 10% as labor-intensive as it was before. The weavers found something else to do, I'm sure, by and large. The combine didn't end civilization by automating the collection of stalks of wheat, corn, and barley, hay, etc., etc., etc., it just made gathering natural inputs to other businesses more efficient, making it easier for the next step in the process to add value, (sorry about all these buzz words, folks, but they DO apply in this case,) resulting in increased gross output of our society, applying downward pressure on prices, raising the cap on the sheer volume of what we produced, which had a chain-reaction effect of making everything that depended on those products as inputs in some way to theirs to be made in greater abundance, increasing the quality of life, life-expectancy, etc., for many segments of society.

    Rather, as a result, some, perhaps many of the people whose jobs were eliminated by the combine got jobs working the corn-flaking machines, giving rise to a whole new way to eat breakfast.

    (While I'm sure it's true, it needs to be said, that some people benefited a lot damn more than others, that's kind of beside the point. The point was that humans are flexible, adaptable, and imaginative problem-solvers, and unless and until AI is able to solve every problem any human could possibly solve, there's still a need for us. Also, I rather doubt AI will reach the point of being any meaningful danger any time soon.)

    Getting back to the topic, the digital electronic computer made human number-crunching professionals very nearly obsolete. Did they experience a mass die-off? No, they put their brain-power to different problems, too complex to be handled by the poor, stupid, dim-witted 8-bit computing devices that were able to replace them on tasks like, "add up this column of 500 numbers, then divide it by the result of step 14, and if the remainder is a non-terminating, repeating decimal..." and probably a lot of them took new jobs programming the very computers that replaced them.

    SURE, it's true, some people can't or won't adapt. But to shake your fists at the bosses who replace you with a machine that can do your job better and cheaper is, looked at the situation from another perspective, like demanding that the boss, because he hired you, is obliged to pay you for EVER. That brings with it numerous problems, and it is besides unfair, and would tend to discourage people hiring folks in the FIRST place, if they know they're going to be punished for offering you a job to begin with, at some point down the road.

    There is good in recognizing the virtue of an honest day's work, and in protecting the rights of laborers, but to pretend that businesses are all 100% evil, parasitic monsters, (the big ones I would more easily argue are that, more often, per capita, than the little ones,) but the way to solve this problem and many others facing us isn't to piss yourselves over AI stealing your job, and making moves to outlaw AI research, etc. That's like trying to plug a hole in a dam from the side the water's coming OUT of, rather than plugging the whole from the backside, with something that can withstand t

They are worth a billion dollars. They have a new drug that will sell for a lot of money in testing. Tests go poorly, the drug probably will have to be withdrawn before it even goes to market. The stock goes down. They have another drug that they're in the middle of a patent lawsuit over. They win. The stock goes up. Traders understand why it happens and are comfortable in investing in such stocks because there are good and bad signs that tell them how a company, and therefore how a stock, is likely to perform.

    The board of directors fires a half-dozen executives whose titles start with "C" (such as the CEO, CTO, CFO, etc.) This likely will drive the stock price either massively down or massively up, depending on WHY they fired them. IF the company had been in trouble, this could be a positive development, and stock value goes UP. Or, if they'd been doing incredibly well, (in the literal sense, doing so well it's hard to believe it's possible, seems to good to be true, etc.,) and they sack the leadership, it's probably the harbinger of bad tidings at that company, and for all people holding their stock.

    It would only be weird if that action had no impact on stock prices at all, and they remained consistent with other, similar companies.

    With Bitcoin, who the fuck KNOWS why it goes up or down? Or maybe it's because the "currency" doesn't DO anything, unlike a company that makes... oh, widgets or something, or a different company that perhaps sells consulting services on the installation and use of... oh, widgets or something. The value allegedly arises from the facilitating of trade itself. It would be if I got a stack of sticky notes, and put a little doodle on each one, and tried to tell people that because my doodles are unique, (let's pretend for a second they are,) that these stickies can be traded as if they're money, and they're therefore worth something, and what would you give me for one?

But no one has any need to buy "701923486..." because any of us can produce that simply by writing, typing, or saying "7," followed by "0," followed by "1," etc. This is the difference between objective existence and being imaginary. Once Pythagoras (or whoever) publicized the observation that the ratio of a circle's circumference to its diameter is always about 22 to 7, they didn't really need his 2s, nor his 7 anymore, to be able to work out how many cubits of cloth would be needed to go around a circle if its diameter was known.

    Here's the thing though. As an admitted trader of Bitcoins, you have a vested interest in other people (such as anyone reading this,) being convinced that they not only exist, but that they're worth a LOT of money, and that their value will only go up and up and up. I , on the other hand, have NO interest either way, not owning Bitcoins and having no intention either ever TO buy, sell, OR own any. So of the two of us, I am the one NOT trying to sell anyone anything here.

    But it seems we'll just have to agree to disagree on the matter. I doubt anything I can write will convince you, and you're not going to convince me, so we seem to have reached a rhetorical impasse. But the good and gentle readers of slashdot will have to decide which of us is right, and good luck to them too.

    In summary, to each his own. Enjoy trading and investing in your imaginary currency, and best of luck to you.

    *Some HAVE made the argument about dollars being fundamentally worthless since they're no longer exchangeable for precious metals by the government, I personally don't, but that's not relevant to the case. You can use them to pay your taxes, they are legal tender, and in other places, whatever THEIR local currency is, you can, again, pay taxes THERE if any taxes you must, using THEIR local currency. Gold and silver fluctuate in value and while both have little intrinsic value (sorry, it's germane to the conversation and a perfectly valid point,) compared to their assigned value due to scarcity and difficulty forging or producing either artificially. But even if people STOP trading them, they don't suddenly turn to smoke and drift away on the breeze. You can still make stuff out of them. Art of various kinds can be made with silver and gold, for example. Plus there are other uses, such as in electronics and biology and medicine, BESIDES as money for them, and others, like copper.

    If (or rather when) people stop trading Bitcoin, it doesn't matter how many you have. They are UTTERLY worthless, and on that day they will become meaningless strings of numbers, and no one will ever pay you even a penny for them.
