For me, its more about the frameworks shoving between you and the presentation layer. It's not realtime and interactive anymore (rather about packed and delayed update/repaint cycles). Consider what could be done alone using the canvas 2d-context with the current API. There isn't a visual thing that couldn't be done with this. Some may remember the creative wealth of CD-ROMs in the 1990s – we may have all of this, but better. Instead, it seems more about a glorified mark down presentation layer. We really could do better.

P.S.: Maybe, this is just an old man's rant about the old days like when PostScript was all written by hand and typo came in stars. But I'm really underwhelmed by the state of creativity on the web.
