I sometimes wonder that too. There are tons of simple things HTTP and web browsers could implement to make everyone's life better and easier. Make redundancy built-in, for example, or a primitive peer-to-peer content delivery for stuff like videos. But then I remember that megacorps always want to keep competition out, make everyone invest a lot into crappy traditional infrastructure to compete. They can't allow a competing alternative to work on many orders of magnitude cheaper infrastructure, they are only interested in increasing that cost for everyone and at such pace that nobody can keep up.
