海外TECH	DEV Community	The Beginning of Infinity by David Deutsch	https://dev.to/sandordargo/the-beginning-of-infinity-by-david-deutsch-599m	The Beginning of Infinity by David DeutschThis is not going to be like my regular book reviews It cannot be It was so long It took me so much time I m reading almost every day after I wake up and before I go to bed Okay I was on vacation while I had this book in the queue where I didn t manage to read as frequently and as much as I wanted but still Usually I finish a book in no more than weeks and this took me about months It might not be more than pages but oh boy those pages are packed So first of all I found The Beginning of Infinity interesting certain parts outright fascinating but I wouldn t recommend reading it if you re not a binge reader probably this would take you out of the book market for too much time So what is this book all about It s basically about human progress Why and how do we evolve and what s the limit of this development As you might imagine the answer to this latter question is that it has none Our progress the progress of knowledge is infinite At many points throughout our history people claimed that it s the end of history it s the end of discoveries but they were never right and probably they never will Otherwise in the book the author touches on the questions of beauty the reasons for creativity mathematical proofs artificial intelligence the evolution of culture and even multiverses and quantum physics At certain points I didn t feel the book a coherent entity but rather a collection of interesting but not very well organized writings I d also not consider this book the one big source of truth even though it seems that Deutsch handles his points infallible and uncriticizable Especially when it comes to quantum theory and multiverses we are not there yet will we ever be to decide to prove whether the hypotheses he shares are the right ones A part of the book that I particularly liked was the last chapters No not because of that Not only But it discussed history Easter Island different points of view on the society of the Easter Island and in general First of all it makes a distinction between static and dynamic societies In static societies change is slow By slow the author means that it s hardly noticeable to the individual the manifestation of changes requires multiple generations It s achieved by suppressing creativity and progress both on central and local levels A dynamic society is therefore a culture where change and progress are fast it s noticeable for the individual The author brings the two ancient Greek city states as examples Sparta was a static society while Athens was a dynamic one Until Sparta defeated it in the Peloponnesian Wars and made an end to the Athenian golden age The next time when a dynamic society started to emerge was the European Enlightenment and the author claims that we are still in a transition from a static to a dynamic society though I m sure many would complain that it s already too dynamic Dynamic societies are able to solve the arising problems with creative solutions And here comes Easter Island into the picture We are not sure when the islanders arrived why they started to raise statues but there are a few things to notice they removed the forests so that they can move the big statues and to build canoes houses to make fires to burn the dead By chopping down the trees in an unsustainable manner they started to have more serious problems instead of changing the course of actions they doubled down and tried to build even more and even bigger statues that fasten up the speed of deforestation until they had no more forests to chop down many of their statues are unfinished and they are all very similar they show no signs of creative progress The Easter Island society when faced with a problem couldn t change their fate they couldn t respond to the challenges Instead they kept doing what they had been doing engraving the situation They showed the signs of a static society and they died That s pretty much what happens to static societies They cannot react to the changing environments to the changing circumstances so they inevitably meet problems where their systems of beliefs and actions become inadequate and their societies collapse A dynamic society on the other hand is adapting and can answer to the challenges of a changing environment Which one do we live in Time will tell but ours show signs of a dynamic society So what do I think about The Beginning of Infinity overall Would I recommend it I don t say that it s a bad book It is an interesting read but very long Only read it if you read a lot and if you are interested in mathematics physics and history at the same time Then it will be interesting But beware it might block your reading queue for more than a month or two	2021-09-25 15:48:27

海外TECH	Engadget	Hitting the Books: How Bitcoin is somehow worth more than the paper it's printed on	https://www.engadget.com/hitting-the-books-the-future-of-money-eswar-prasad-harvard-university-press-153024975.html?src=rss	Hitting the Books How Bitcoin is somehow worth more than the paper it x s printed onBitcoin and similar blockchain based cryptos exhibit the same radical divergence from traditional scarcity economics that we first saw when MPs and Napster cratered physical album sales at the turn of the century Unlike gold which derives its value from both its myriad uses in fashion and industry as well as the difficulty involved in extracting it from the Earth acquiring new Bitcoin is as simple as digitally mining more of the stuff In his latest book The Future of Money Senior Professor of Trade Policy at Cornell University Eswar S Prasad deftly examines how we collectively assign value to these digital constructs and what that means for the economics of tomorrow nbsp nbsp nbsp Harvard University PressCopyright by the President and Fellows of Harvard College Used by permission All rights reserved At a conference held in Scotland in March then Bank of England governor Mark Carney observed that “the prices of many cryptocurrencies have exhibited the classic hallmarks of bubbles including new paradigm justifications broadening retail enthusiasm and extrapolative price expectations reliant in part on finding the greater fool The last phrase in his statement was an allusion to the period of seemingly ever rising real estate prices during the US housing boom of the early to mid s High and rising real estate valuations seemed to be based on the notion that all it took to make money from a house purchased at inflated prices was to find just one buyerーan even greater fool than oneselfーwilling to pay an even higher price Carney s speech came on the heels of another by Agustín Carstens head of the Bank for International Settlements he described Bitcoin as “a combination of a bubble a Ponzi scheme and an environmental disaster Skeptics including central bankers and academics correctly note Bitcoin s extremely volatile prices and the periodic price collapses it has experienced Indeed from an economist s perspective there is no logical reason Bitcoin should be priced beyond its value in providing an anonymous payment mechanism let alone the sort of value it commands Yet even as it has shed all pretense of being an effective medium of exchange Bitcoin has maintained the faith of its adherents It seems not just to persevere but has become an increasingly prized store of valueーor perhaps more accurately an attractive speculative asset at least as this book is being writtenーthis could all change in a moment What accounts for this To address this question we must first consider what gives a financial asset tangible or not economic value For one thing an asset represents a claim on future goods and services Owning a share of stock or debt issued by a firm is a claim on the firm s future earnings which in turn is based on its ability to create real products or services that have monetary value The same is true for real estate which yields real services to homeowners or renters that can be monetized Owning a government bond is in principle a claim on future government revenues which could come from taxes or other sources Gold is dif­ferent It has an intrinsic value based on its industrial use and it is also used in jewelry and tooth fillings But its market value seems far greater than its intrinsic value based on these uses It appears that gold derives its value mainly from scarcity rather than its usefulness or any claim it offers of a future flow of goods and services Scarcity by itself is clearly not enough there has to be enough demand for an asset as well Such demand could hang on a thread as slender as a collective belief in the market value of the assetーif you think there are other people who value gold as much as you do and enough people feel the same way gold has value So is Bitcoin just a digital version of gold with its value determined mainly by its scarcity The limit of twenty one million bitcoins is hardcoded into the algorithm making it scarce by construction But there still needs to be demand for it as even Bitcoin cannot escape the basic laws of market economics especially the determination of prices based on supply and demand Such demand could of course be purely speculative in nature as seems to be the case now that Bitcoin is not working well as a medium of exchange It does take copious amounts of computing power and electricity to mine Bitcoin and unfortunately computers and electricity have to be paid for in real moneyーwhich is still represented by fiat currencies It has been argued that Bitcoin s baseline price is determined by this mining cost One research company estimated the electricity cost of mining one bitcoin in the United States to be about in Another company estimated the overall break even cost of mining a bitcoin in at suggesting that this constituted a floor for its price But this is hardly reasonable logic Just because something takes a lot of resources to produce is not enough to create demand for it and therefore to justify its price Bitcoin devotees needless to say have an answer for this given the technologically inclined nature of this community it had to be a quantitative model The model if it can be called that uses the ratio of the existing stock relative to the flow of new units as an anchor for the price Consider gold The total stock of gold that exists in the world above ground is estimated at about metric tons Roughly tons of gold are mined each year which amounts to about percent of the existing stock Thus the stock to flow ratio is about sixty It would take that many years for annual gold production assuming it continues at the average rate to reproduce the existing stock For silver this ratio is about twenty two The logic of this pricing model appears to be that even doubling the annual rate of gold or silver production would leave their stock to flow ratios high in which case they would remain viable stores of value with high prices The physical constraints on supplyーramping up mining operations would take a long timeーmean there is little risk of a surge in supply knocking down prices of the existing stock By contrast for other less precious commodities including metals such as copper and platinum the existing stock is equal to or lower than annual production Thus as soon as the price begins rising production can be ramped up preventing large price hikes With these commodities prices are more closely tied to values based on industrial and other practical uses In the stock of Bitcoin that had been mined was estimated to be around twenty five times larger than that of the new coins produced in that year This is high but still less than half of the stock to flow ratio for gold Around Bitcoin s stock to flow ratio is expected to overtake that for gold Thus if one accepts this logic the price of Bitcoin must eventually rise This valuation is built entirely on a fragile foundation of faith As one influential Bitcoin blogger puts it “Bitcoin is the first scarce digital object the world has ever seen Surely this digital scarcity has value This blogger makes profuse allusions which are echoed on most websites and chat boards frequented by Bitcoin adherents to how Bitcoin and gold are analogous “It is the consistently low rate of supply of gold that is the fundamental reason it has maintained its monetary role throughout human history The high stock to flow ratio of gold makes it the commodity with the lowest price elasticity of supply Fiat money and other cryptocurrencies that have no supply cap no Proof of Work consensus protocol and no need of large amounts of computing power to keep operating are seen as less likely to retain value because their supplies are not constrained and can be influenced by the government or small groups of individuals or stakeholders Clearly logic and reason are not important underpinnings of Bitcoin valuations And it is hard to argue as I have learned with a twenty fiveyear old who bought his first bitcoin at then kept buying and now views every dip in Bitcoin prices as a buying opportunity to add to his stash But as an economist one does worry for that young man whom I sat next to at a conference in January and with whom I ended up having a long and heated discussion and others who have bet their life savings on Bitcoin and other cryptocurrencies Then again with the price of Bitcoin where it is in April perhaps my time would have been better spent in the past few years acquiring some bitcoin rather than laboring on this book	2021-09-25 15:30:24
