海外TECH	Engadget	Hitting the Books: How Amazon's aggressive R&D push made it an e-commerce behemoth	https://www.engadget.com/hitting-the-books-the-exponential-age-azeem-azhar-diversion-books-153033895.html?src=rss	Hitting the Books How Amazon x s aggressive R amp D push made it an e commerce behemothAmazon is the Standard Oil of the st century Its business operations and global reach dwarf those of virtually every other company on the planet ーand exceed the GDP of more than a few countries ーillustrating the vital importance innovation has on the modern economy In his latest book The Exponential Age How Accelerating Technology is Transforming Business Politics and Society author Azeem Azhar examines how the ever increasing pace of technological progress is impacting influencing ーand often rebuilding ーour social political and economic mores from the ground up Diversion BooksExcerpted from The Exponential Age How Accelerating Technology is Transforming Business Politics and Society by Azeem Azhar Copyright Azeem Azhar Printed with permission of the publisher Diversion Books All rights reserved In Amazon turned twenty six years old Over the previous quarter of a century the company had transformed shopping With retail revenues in excess of billion it was larger than Germany s Schwarz Gruppe America s Costco and every British retailer Only America s Walmart with more than half a trillion dollars of sales was bigger But Amazon was by this time far and away the world s largest online retailer Its online business was about eight times larger than Walmart s Amazon was more than just an online shop however Its huge operations in areas such as cloud computing logistics media and hardware added a further billion in sales At the heart of Amazon s success is an annual research and development budget that reached a staggering billion in and which is used to develop everything from robots to smart home assistants This sum leaves other companies ーand many governments ーbehind It is not far off the UK government s annual budget for research and development The entire US government s federal R amp D budget for was only billion nbsp Amazon spent more on R amp D in than the US National Institutes of Health Roche the global pharmaceutical company renowned for its investment in research spent a mere billion in R amp D in Meanwhile Tesco the largest retailer in Britain ーwith annual sales in excess of £ billion approximately billion ーhad a research lab whose budget was in the “six figures in Perhaps more remarkable is the rate at which Amazon grew this budget Ten years earlier Amazon s research budget was billion Over the course of the next decade the firm increased its annual R amp D budget by about percent every year As the s went on Amazon doubled down on its investments in research In the words of Werner Vogels the firm s chief technology officer if they stopped innovating they “would be out of business in ten to fifteen years In the process Amazon created a chasm between the old world and the new The approach of traditional business was to rely on models that succeeded yesterday They were based on a strategy that tomorrow might be a little different but not markedly so This kind of linear thinking rooted in the assumption that change takes decades and not months may have worked in the pastーbut not anymore Amazon understood the nature of the Exponential Age The pace of change was accelerating the companies that could harness the technologies of the new era would take off And those that couldn t keep up would be undone at remarkable speed This divergence between the old and the new is one example of what I call the “exponential gap On the one hand there are technologies that develop at an exponential paceーand the companies institutions and communities that adapt to or harness those developments On the other there are the ideas and norms of the old world The companies institutions and communities that can only adapt at an incremental pace These get left behindーand fast The emergence of this gap is a consequence of exponential technology Until the early s most companies assumed the cost of their inputs would remain pretty similar from year to year perhaps with a nudge for inflation The raw materials might fluctuate based on commodity markets but their planning processes institutionalized in management orthodoxy could manage such volatility But in the Exponential Age one primary input for a company is its ability to process information One of the main costs to process that data is computation And the cost of computation didn t rise each year it declined rapidly The underlying dynamics of how companies operate had shifted In Chapter we explored how Moore s Law amounts to a halving of the underlying cost of computation every couple of years It means that every ten years the cost of the processing that can be done by a computer will decline by a factor of one hundred But the implications of this process stretch far beyond our personal laptop useーand far beyond the interests of any one laptop manufacturer In general if an organization needs to do something that uses computation and that task is too expensive today it probably won t be too expensive in a couple of years For companies this realization has deep significance Firms that figured out that the effective price of computation was declining even if the notional price of what they were buying was staying the same or even rising could plan practice and experiment with the near future in mind Even if those futuristic activities were expensive now they would become affordable soon enough Organizations that understood this deflation and planned for it became well positioned to take advantage of the Exponential Age If Amazon s early recognition of this trend helped transform it into one of the most valuable companies in history they were not alone Many of the new digital giantsーfrom Uber to Alibaba Spotify to TikTokーtook a similar path And following in their footsteps were firms who understand how these processes apply in other sectors The bosses at Tesla understood that the prices of electric vehicles might decline on an exponential curve and launched the electric vehicle revolution The founders of Impossible Foods understood how the expensive process of precision fermentation which involves genetically modified microorganisms would get cheaper and cheaper Executives at space companies like Spire and Planet Labs understood this process would drive down the cost of putting satellites in orbit Companies that didn t adapt to exponential technology shifts like much of the newspaper publishing industry didn t stand a chance We can visualize the gap by returning to our now familiar exponential curve As we ve seen individual technologies develop according to an S curve which begins by roughly following an exponential trajectory And as we ve seen it starts off looking a bit humdrum In those early days exponential change is distinctly boring and most people and organizations ignore it At this point in the curve the industry producing an exponential technology looks exciting to those in it but like a backwater to everyone else But at some point the line of exponential change crosses that of linear change Soon it reaches an inflection point That shift in gear which is both sudden and subtle is hard to fathom nbsp Because for all the visibility of exponential change most of the institutions that make up our society follow a linear trajectory Codified laws and unspoken social norms legacy companies and NGOs political systems and intergovernmental bodiesーall have only ever known how to adapt incrementally Stability is an important force within institutions In fact it s built into them The gap between our institutions capacity to change and our new technologies accelerating speed is the defining consequence of our shift into the Exponential Age On the one side you have the new behaviors relationships and structures that are enabled by exponentially improving technologies and the products and services built from them On the other you have the norms that have evolved or been designed to suit the needs of earlier configurations of technology The gap leads to extreme tension In the Exponential Age this divergence is ongoingーand it is everywhere	2021-10-16 15:30:33
