As for me, this is what I'd do. Though it too may end up being more than 3 things.
And of course I know the technology is still in the infant-stage, very primitive, and as yet wholly undeveloped compared to the possibilities. And you'll also need input and output devices, and computers, and networks that will support such developments, but given those caveats a'priori, this is what I'd do:
1. Visiting an internet site would be like visiting an "Enhanced Real World" site. It would not be like visiting a current site. It would be like going to a real place (far better and far more realistic than current virtual world sites), only there would be add on levels of para-naturalism. Where things that cannot happen in real life, or that would be extremely difficult to do in real life, would be possible. I'd eliminate all but the most absolutely necessary text and text interactions. Visiting sites on the internet would be experientially and sensually interactive, as in real life. Information would be exchanged in a sensory and experiential fashion, as in real life, with data packet back-ups or carry outs as an additional add on.
For instance if one visited a site about Russian Vikings then it would be like going to a Russian Viking village. You'd talk to other visitors and you'd talk to Viking era guides and inhabitants of the village. If you wanted specific information you could talk to a village elder and buy a virtual book which you'd take with you back to your "home" (on your computer) and could be installed and that book would contain "the exchanges" which would include data, text, histories, backgrounds, demonstrations, sounds, examples, etc. that could be used on your computer. It'd be like installing a micro-version of the Russian Viking internet site you just visited on your site.
This would also be true of visiting a web based store. Instead of going to a site and seeing a picture of and/or write up of a product, you'd be able to examine and pick up a virtual version of the product, scan it with a virtual device, and the scan would contain all relevant information on the product, such as compatibility, functions, etc. You'd even be able to scan a virtual simulation of the product that you could then transfer instantaneously to your "Home Space" to see how it would look and behave in the area of your own home where the real product would be installed.
2. Black Webs and Secerned Nets - I would greatly enhance and enlarge Black Web sites. I would also begin to break the web apart into sub-Realms or sub-areas that people could visit that would have a particular culture or specialized on a particular subject matter. The web is simply too big, and has been for awhile, to be properly managed as a single domain (open to all at all times) enterprise. The way the internet operates now guarantees crashes and overtaxed technological and system networks.
These divisions could be like nations (divided by a culture), like cities (divided by smaller areas with a wide range of smaller activities within them), or they could be divided like subject matter categories (a library). Though there is no reason that you couldn't have different types of divisions all operating simultaneously.
(Actually these divisions already exist - LANs, RANS, etc. - for security purposes, for instance there are military and governmental and corporate sub-webs that cannot be accessed without the proper security protocols or without hacking or cracking attempts. But I'm talking more about divisions for enhanced and easier use, not division for restricted physical or security access.)
3. Alpha Areas - although I am in no way wedded to this idea it is my attempt to solve some of the funding difficulties inherent in the Web and in developing the Internet properly. I would allow and encourage the development of Alpha, Beta, Gamma, and Delta Areas and sites on the Web.
Alpha areas and sites would be entirely for profit and funded by Free Market business and commercial activity. They would probably also be paid areas and sites that you'd either pay a fee to visit or become a member through a pay structure.
Beta would be partial pay.
Gamma would be for various governmental interests.
Delta would be free, public access areas and sites.
To use the City analogy above. Say you had a Secerned Net that was structured like a city. In any city are areas and buildings and sites you can only visit by paying for access, areas that only certain cooperative members can visit (such as workers at a business), and areas that are free to all, such as parks and public areas.
Well, that's all I have time for now. Thanks for your responses.
Janx, I liked your cyberspace idea but couldn't give you XP for it. Wouldn't let me.
