The perceived benefit of creating a new framework is large (I'll solve programming the internet!) and the cost is quite small (easy to write js with little knowledge), there's a huge number of devs, and no one really owns the space. Compare it to say, creating a new operating system. Sure the world could benefit from a better OS, so why not make one? The perceived benefit is small (why do this when Linux exists) and the cost is large (it's hard and you need a lot of knowledge). Also a lot of half baked ideas. The number of js writers is huge but on average very inexperienced compared to other languages.
