Out of the ether
Here you can find an interesting economy market lesson, in which one can learn that having just vision and brilliant ideas is not enough to transform a concept into a true technology embraced by the whole world.
If you use a personal computer, you almost certainly use Ethernet. Today, Ethernet stands as the dominant networking technology—the backbone of corporate networks and the emerging wireless WiFi networks. Its success stems from its nimbleness and ability to mutate. At 30+ years old, it is exceptionally long-lived for a digital technology, and yet, there seems to be plenty of room left for advances.
Bob Metcalfe transformed one of the concepts in fashion at Xerox's Palo Alto Research Centre (PARC) in the 70s - sending information by breaking it into ”packets“ of data and reassembling the packets - in a whole business.
But Ethernet itself was just part of a project that made Xerox's Palo Alto Research Centre (PARC) legendary. That project, the Alto computer, would predict most of the concepts of computing that the world is familiar with today: the graphical user interface, the high-resolution display, the word-processor, a version of the mouse and, of course, connectivity. It seems almost unbelievable for the 21-st century multimedia consumer.
Despite the vision behind, little remains of the original 1974 version of Ethernet. The only similarity between that three megabits-per-second protocol and the 100 gigabits-per-second version under development today is the packet definition and the notion that underlies the network: that packets are unreliable, forcing the protocol to check their transmission. But yet, that is enough.
As Ethernet has spread, individual brilliance has mattered less in the process of development. Rather, the collective ingenuity of people such as Andy Bechtolsheim (co-founder of Sun Microsystems and subsequently Granite Systems) and Judy Estrin (a serial entrepreneur in the packet-switching business) was crucial to drive the technology through the standards bodies.
And yet, a lot of lobbying, brainstorming and clever marketing were needed to turn it into a global standard.
