I agree that HTML+javascript has serious limitations. But eventually GUI complexity can be managed through good APIs (XUL, flex), and high-bandwidth apps can be delivered through plugins that use lower-level protocols (flash). The current state of these technologies still seem less-than-optimal, but I can see a lot of effort being put into making things more transparent and efficient.
