We have stagnated because new APIs, frameworks, environments appear at a rate too high for anyone to build meaningful things on top of them before they become obsolete again. We also wait longer until we adopt these new technologies, therefore narrowing the time frame to actually use them even more. Low end devices are a good point, my main gripe with all these frameworks is that they make it very easy to break many conventions of the web (URLs no longer work as intended, extra efforts is needed to make the pages crawlable etc.).
