"It's really unfortunate that so many people aren't interested in learning Ember."
Is that the sentence? I dunno. I looked at the stats for the first version of Angular and it had a low rate of "heard of it, not interested" and a high rate of "used it, will never use it again" with Ember being the reverse of that. I was just like "awh man, what a pity" because I have really been enjoying my short time with the framework.
"...to hack things together quickly..." That wasn't really what I was getting at. There is a lot of negative connotation around the word "hack." I want something that is easy to setup quickly as well as easy to reason about. With jQuery, I can just point to a CDN and get going. As far as the concept, I can easily understand that I'm just selecting and changing an element of the DOM.
Now, I recognize that jQuery gets super messy and has a lot of inherent limits but the spirit of the approach is something that I admire. Ember, like many front end frameworks, brings organization, conventions for testing, etc... but the concepts are a bit easier for me to grok than some of its competitors and there exists some tooling that removes a barrier to entry for me. That's just my anecdotal experience and others mileage may vary.
"For people that do frontend/JavaScript full time..." Yeah, I dunno. I'm just someone who does front end work for open source projects and when I think it has its role within my regular duties as someone who does more operations work. That being said, I think there are a lot of people out there like me. People who just want to show up at a hackathon and get moving quickly because they have that back end experience but are unsure of themselves when it comes to front end development.
