I did already. You seem more interested in beating your chest and insulting me than in thinking about the problem. The example I gave is as follows: the choice of SHA256 and its particular use in Bitcoin will, if Bitcoin grows, create incentives for the development of better GPUs and create economies of scale for those organized on principles like AMD's. That can have positive effects for those who use the cards both for Bitcoin (which is internalized) and for other purposes (which is an externality, from Bitcoin's perspective).
Excuse my Wikipedia: "In economics, an externality (or transaction spillover) is a cost or benefit, not transmitted through prices,[1] incurred by a party who did not agree to the action causing the cost or benefit."
What you are describing is the direct consequence of AMD's business strategy, which graphics branch produces parallel computing processors and have decided before Bitcoin existed to widen their driver support to other tasks requiring parallel computing. Confusing externalities with a business plan, that only confuses the discussion. Once more, be rigorous. Unless you are going to pretend to me that miners nor gamers want faster, more power efficient hardware.
Then again this a discussion on semantics. If your point all along was "Bitcoin should be designed to have good impact on the world oustide of being a crypto currency", my answer doesn't change too much: it has no room for such a thing, nor does it users care. The existence of Bitcoin alone is cause enough.
Really? The examples are endless. A particular file format for storing graphics could be more or less amenable to steganography than its competitors. A music file format could encourage or discourage the sale of particular kinds of speakers, based on the frequencies that the format faithfully replicates; that in turn could influence how music is written and enjoyed.
None of these are ACTUAL examples. Just chimeras in your head. My tendency of thinking you're a troll is that you have failed so far to provide anything but speculation when asked otherwise. My insistence in asking for an actual, real life example of your claims is so that you understand the detachment your perception of this project has with the reality of its development. What incentive would one have to spend efforts in researching positive externalities for Bitcoin when building and updating the project unless these externalities have a direct consequences on the project, in which case they are not externalities anymore, are they?
You do understand that to incorporate externalities implies limiting your choice in developmental possibilities by rules that are not directly related to the goal of the project. Which begs the question:
Of course many features of it are. Chances, and judgments, were taken in the original design and in the modifications throughout its ongoing adoption. Magic numbers are always in some sense arbitrary, but they're a necessary feature of the design of many protocols. But the choices and judgments don't stop there.
How can externalities be voluntarily implemented if the design choices are arbitrary? Surely if the functionalities the project has to deliver are precise and legion, this will restrict the design choices, which hurts your idea that any precise piece of software is designed on lsd at 4am. This isn't a governmental project afaik.
Is Facebook a crap shoot? Yes. The problematic is far too unclear for a precise developmental line to be isolated. Is h.264 a crap shoot? Certainly not. But somehow you are thinking that there is a lot of leeway in Bitcoin's developement. So again, I'll tell you, the conditions needed to establish a decentralized, currency worthy, virtual commodity are pretty restrictive.
The adoption by any P2P community of any software is in some sense arbitrary and based on marketing, goodwill, and the vagaries of self-interest and public-interest.
There is no marketing in Bitcoin's, since there is no one selling you access to it. As for self and/or public interest, what is arbitrary about that? This isn't a dc++ vs torrent turf war, it is the establishment of a currency. Again, precise guidelines, known problematics.
I didn't mean to threaten you in any way, but I appear to have triggered a needlessly emotional response. I don't know why. You don't have to continue in the conversation if it upsets you or if you think I'm producing noise without purpose. That I'm being as respectful to you as I am, with huge restraint, should be an indication that I'm not trolling for angry responses.
None of this. I am being perfectly respectful with you by explaining why you are ignorant on the matters you are discussing, by pointing how detached you are of certain realities of this project. Was I to praise you for them, then I'd be a hypocrite, wouldn't I? To summarize this discussion, you go something like "Hey, cars polute and waste energy by using oil, why haven't you guys built an engine that turns oil waste into pizzas?", then I come in, tell you that's not gonna happen for several reasons that I outline, and you call me a combustion engine jingoist. My stance is the same as someone witnessing a newcomer question a research group on energy about why they're not researching perpetual movement.
But I agree with you more generally; you're hitting on something important. Ignoring spillover effects is the methodology either of the impractical academic or the philosophical conceptualist; it would be like saying "don't think about global warming; we're designing CARS here." The typical way to address a highlighted spillover effect satisfactorily is to show either than it's not important or that it's impossible to address . . . .
Scuse me what? If that company can make a business of selling polluting cars, so be it. The responsibility lies on the consumer, not the manufacturer. No one is forcing you to buy that car, and by buying it and using you are ruining the atmosphere, not the manufacturer. If you only buy clean cars, manufacturers will have to adapt and integrate that to their business strategy. This about as bad as saying guns kill innocents so manufacturers should only sell rubber bullets.
