25 cose da sapere sul web nel 25° anniversario della sua apertura al mondo.

1 The importance of "permissionless innovation"
The thing that is most extraordinary about the internet is the way it enables permissionless innovation. This stems from two epoch-making design decisions made by its creators in the early 1970s: that there would be no central ownership or control; and that the network would not be optimised for any particular application: all it would do is take in data-packets from an application at one end, and do its best to deliver those packets to their destination.

It was entirely agnostic about the contents of those packets. If you had an idea for an application that could be realised using data-packets (and were smart enough to write the necessary software) then the network would do it for you with no questions asked. This had the effect of dramatically lowering the bar for innovation, and it resulted in an explosion of creativity.

What the designers of the internet created, in effect, was a global machine for springing surprises. The web was the first really big surprise and it came from an individual – Tim Berners-Lee – who, with a small group of helpers, wrote the necessary software and designed the protocols needed to implement the idea. And then he launched it on the world by putting it on the Cern internet server in 1991, without having to ask anybody's permission.
