I don't believe you can create a exiting HTML web page with out effort. The creativity factory is what makes a web page good. If you just copy everybody's els e's web pages and take stuff on them your not going to make something exciting. I think that editors will get complex enough so that it can create better graphics at a faster pace. Quality is a different topic though.
Quality depends on creativity.
I can see that when VRML becomes popular, that more advanced editors will be produced. They could make it so that the user chooses shapes, size of shape, position of shapes. Looking at some of the VRML code it looks like it would not be that hard to create a editor that could translate the values into VRML code. Science fiction writers have imagined cyberspace in many different ways. I don't think VRML is the first step for science fiction authors.
