How would you know your UI isn't limiting you?
I looked at Coffeescript once a long time ago and was like, "This doesn't feel any better," and "This is a waste of time."
It might have helped that in the years between I did a lot more Scala, Python and Ruby...and Coffeescript really incorporates some of the amazing concepts about those languages into it.
It's like Java. Once you use Scala or Groovy for a while, you'll be like "WTF?! How did I live doing this terrible stuff in Java when all these newer JVM languages let me use all my old Java libraries with way less code, less boiler plate and cleaner syntax."
Seriously dude, if you don't try something...and by that I mean give it a fair shot, you shouldn't criticize it. You sound like "Get of my lawn."
I for one have used Photoshop since 3.0 all the way to CS6 and CC. I have also used Gimp for years. Today I only use Gimp for small quick things: cropping, resizing
