"I don't like it because it's hard" is not necessarily a good way to evaluate a technology.

JQuery does things in a very standard way, and has been the go-to tool for developers for years. Devs grow up on it, get used to it and find it difficult to fit new ways of working into their mental model. It's like shifting from procedural to functional: the concepts are a alien and because they don't fit & there's a psychological block to learning it.

Not sure that dooms it to failure... maybe to adoption by the masses.
