(Now More Than Ever) You Might Not Need JQuery

As for a "compelling enough reason", I don't know about you, but for me, "staying current" is the single most important aspect of my job as a web developer. If I'm not keeping up, I'm falling behind.
The last sentence of the article sums that idea up pretty well:
"... jQuery will increasingly be seen as a bygone relic from the DOM's dirty past."
Also, giving up JQuery doesn't necessarily mean that you also have to give up consistency. You and your teammates just get to decide on what the "new consistency" will be. It might even be fun?
Staying current is, in my situation, a luxury I can't afford. We have a web project using third party libraries and UI Frameworks which depend on JQuery. As the project is complex and already has a lot of code, kicking JQuery out is not an option (or, at least, neither trivial, nor quick). I'm sure this happens often with legacy software.
