I recently forced myself to get my head around some of the jargon and the ideas surrounding the Web. Here is my summary of what these terms mean and where the digital world is going...
Web 1.0: The first generation of internet technology. You call up pages of text and images with incredible speed and facility. It’s no different from strolling through a library, only much quicker. The operative verb is I LOOK. I look at pages on the screen just as I look at pages in a book. All content is provided for you – it’s a form of publishing. It may be updated in a way that is impossible when a solid book is sitting on your shelf, but you can’t change the content yourself.
Web 2.0: The second generation of internet technology allows for user-generated content. You don’t just look at the pages, you alter them. You write your own blog; you comment on someone else’s article in the comment boxes; you edit an entry on Wikipedia. And then, by extension, with basically the same technology, you share your thoughts on a social networking site, which means you are commenting not on a static site, but on something that is itself in flux. You have moved from action to interaction; from connection to interconnection. If Web 1.0 is like a digital library, Web 2.0 is like a digital ‘Letter to the Editor’, a digital conference call, a digital group discussion. The verb here is I PARTICIPATE.
Web 3.0: People disagree about the meaning of Web 3.0, about where the web is now going. I like John Smart‘s idea of an emerging Metaverse, where there is a convergence of the virtual and physical world. In the world of Web 2.0, of user-generated content and social networking, you stand in the physical/natural/real world and use the new media to help you around that world – the new media are tools. You talk to friends, you share ideas, you buy things that have been suggested and reviewed by others. But in Web 3.0 the new media become an essential part of the world in which you are living, they help to create the world, and you live within them.
The border between Web 2.0 and Web 3.0 is not tidy here, because Web 3.0 is partly about Web 2.0 becoming all-pervasive and continuous, so that your connection with the web and your social network is an essential part of every experience – it doesn’t get switched off. The mobile earpiece is always open to the chatter of others; the texts and status updates of your friends are projected into the corner of your Google Glasses (like those speedometers that are projected onto the car windscreen) so that they accompany what you are doing at every moment – the connection between real and virtual, between here and there, is seamless; the attention you give to every shop or product or street or person is digitally noted, through the head and eye movement sensors built into your glasses and the GPS in your phone, and simultaneously you are fed (into the corner of your glasses, or into your earpiece) layers of information about what is in front of you – reviews of the product, reminders of what you need to buy from the shop, warnings about the crime rate on this street, a note about the birthday and the names of the children of the person you are about to pass, etc. This is augmented reality or enhanced reality or layered reality.
It’s no different, in essence, from going for a stroll in the mid-70s with your first Walkman – creating for the first time your own soundtrack as you wander through the real world; or having the natural landscape around you altered by neon lights and billboards. But it is this experience a thousand times over, so that it is no longer possible to live in a non-virtual world, because every aspect of the real world is already augmented by some aspect of virtual reality. The verb here is I EXIST. I don’t just look at the virtual world, or use it to participate in real relationships; now I exist within this world.
Web 4.0: Some people say this is the Semantic Web (‘semantics’ is the science of meaning), when various programmes, machines, and the web itself becomes ‘intelligent’, and starts to create new meanings that were not programmed into it, and interact with us in ways that were not predicted or predictable beforehand. It doesn’t actually require some strict definition of ‘artificial intelligence’ or ‘consciousness’ for the computers; it just means that they start doing new things themselves – whatever the philosophers judge is or is not going on in their ‘minds’.
Another aspect of Web 4.0, or another definition, concerns plugging us directly into the web: when the boundary between us and the virtual world disappears. This is when the virtual world becomes physically/biologically part of us, or when we become physically/biologically part of the virtual world. When, in other words, the data is not communicated by phones or earpieces or glasses, but is implanted into us, so that the virtual data is part of our consciousness directly, and not just part of our visual or aural experience (the films Total Recall, eXistenZ, and the Matrix); and/or, when we control the real and virtual world by some kind of brain or neural interface, so that – in both cases – there really is a seamless integration of the real and the virtual, the personal/biological and the digital.
If this seems like science fiction, remember that it is already happening in smaller ways. For example, read this MIT review of brain-computer interfaces. In this version of Web 4.0 the verb is not I exist (within a seamless real/virtual world), it is rather I AM this world and this world is me.
Watch this fascinating video of someone’s brainwaves controlling a robotic arm:
This is someone making things happen in the real world just by thinking! (Which, come to think of it, is actually the miracle that takes place whenever we doing anything consciously!)
So what do you think - are you already living in Web 3.0 or 3.5? Do you like the idea of your children growing up in Web 4.0? What will Web 5.0 be?
