From what I gather from the few examples in the post, is that JavaScript has incorporated a lot of the ideas in JQuery, thus making JQuery itself a tad redundant.

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?
