Esse é o quarto post sobre o livro Plano B preparado pelo autor. No final dele estão os links para os detalhes do livro no site, ou então para os sites de venda das livrarias. Aproveite tudo o que o John tem a dizer, qualquer dúvida, cheque no site dele: www.thackara.com:
For me, the most important potential impact of wireless communication networks—or “mediascapes” as Hewlett-Packard dubs them—will be on the resource ecologies of cities. As I explained in my discussion of logistics in chapter 3, wireless communications connecting people, resources, and places to one another in new combinations on a real-time basis is a phenomenon called demand-responsive services. Combinations of demand-responsive services, location awareness, and dynamic resource allocation, have the potential to reduce drastically the amount of hardware—from gadgets to buildings—that we need to function effectively in a city.
Taxi systems are demand-responsive services, to a degree. The old model was that you would ring a dispatcher, the dispatcher would offer your trip all the drivers via a radio circuit, one driver would accept the job, and the dispatcher would send that driver’s taxi to you. A better way has now been introduced in many cities: You ring the system, the system recognizes who you are and where, it identifies where the nearest available taxi is, and it sends that taxi to you. This is dynamic, real-time, resource allocation in action. Now: Replace the word “taxi” in the preceding description with the word “sandwich.” Or with the words “someone to show me round the backstreets of the old town.” Or the words “nerd to come and fix my laptop.” Or the words “someone to play ping pong with.” Likewise for those who have something to offer or information to provide, as opposed to needing or wanting something. Suppose I feel like helping out in a school and hanging out with kids for a day. I might have some time free, or make good sandwiches, or know the old town like the back of my hand, or know there’s a ping-pong table in Mrs. Baker’ garage that the Bakers never use. What do I do? I can call the system, or the system can call me.
A city full of people can now be seen as a live database, full of knowledge, time, and attention—incarnated in human beings—that any of us might use. Louis Kahn talked about the city as a “place of availabilities” with wireless networks and search technologies, the potential becomes actual.
