This is a lot like Hollywood. Movies with enormous budgets look great, but the storyline and direction is lacking. Films made more cheaply are often better. The same dynamic exists on the web. Websites that look better require newer software to run.
Faster machines are more expensive.
These websites need big files. This too costs more. The end result is that the Internet becomes expensive. Too expensive to be used by most people. If we're not careful we could end up with a Web entirely like this, a Web that discrimates between people based on their computer and software.
