Variables would have to be linked into various other HTML commands to enable the script to actually do anything. The above principles can be used to write an operating system so that the same simple method is used from bottom to top. It is possibly true that these principles should also be built into the manufacture of microprocessors. If so then it is sad this has not already been done. Surely we are not utilising the power already waiting in the Web structure itself.
Hypertext works because it mimics the hyper-dimensional linking in the brain.
After all you can link from jpg's too. If we think of a neuron as a Web page then processing needs adding within the page. A rough first shot at this has been taken above. Sorry for the long post.
