Speaking for myself, I've been through six different frameworks/versions of "data binding", starting with VB3, now all the way through AngularJS. I've got 20 years of similar examples in DBMSs, distributed protocols, GUI design, testing, requirements, etc.
It's not that I refuse to learn new technologies, because I've taken on new things every year that I've worked in this field. jQuery? Love it. HTML5, CSS transitions? B-E-A-utiful. Bootstrap? You betcha.
I do, however, refuse to make all the same mistakes and work through the same leaky abstractions and other problems just to try the new hotness. A great example is the NoSQL movement - now that Postgres supports JSON documents (and has had great K-V support for a while now), I'll be very happy to exploit those features without wrestling MongoDB or Firebase to the ground.
