Something about these modern UI frameworks, like Vue, perhaps.
The fact that one has to learn mind numbing levels of abstractions, contortions, domain specific knowledge, virtual DOM's and all this with the hindsight that this could soon be out the door just like any number of mootools, extJS's before it. All this effort to get a SPA or a smoother UX interaction doesn't seem to be as appealing.
Given that the basic UX functionality can be achieved with plain html and js in a fraction of the time and effort (minus the smoothness) since the ~2010's.
