Technology, finance and China
Yet both sides agree that the internet world is being transformed by a number of powerful forces, three of which stand out. First, technological progress has made it much simpler and cheaper to try out myriad bright ideas for online businesses. Second, a new breed of rich investors has been keen to back those ideas. And, third, this boom is much more global than the last one; Chinese internet firms are causing as much excitement as American ones.
Start with technology. Moore’s law, which holds that the number of transistors that can be put on a single computer chip doubles roughly every 18 months, has continued to work its magic, leading to the proliferation of ever more capable and affordable consumer devices. Some of today’s tablet computers and smartphones are more powerful than personal computers were a decade ago. IDC, a research firm, estimates that around 450m smartphones will be shipped worldwide this year, up from 303m in 2010.
Moore’s law also underpins the growth of “cloud” services, such as Apple’s iTunes music store, which can be reached from almost any device, almost anywhere. Such services are hosted in data centres, the factories of the cloud, which are crammed with hundreds of thousands of servers, whose price has plunged as their processing power has soared. Everything is connected ever faster, with ever fewer wires.
