Most of the interesting parts of the web are not static and you do need some scripting language to have an interactive site. Most users are on complex web apps its why people open their browsers everyday. The internet should be more than a wiki and blogs it needs complex applications and any future web proposal should be leveraging what we can do to solve problems we face not saying "just make simpler things like wiki and blogs". Bloat is a non issue, people naturally optimize their websites to provide a good experience. Even the heaviest fattest frameworks still load nearly instantly. Bring in 50 ad providers and it still loads in a second.
