This reaction to Ember just baffles me. Your day job is to 
  build a piece of web software and you can’t take a few 
  days to learn the ins and outs?

What compelling reason can you give me to take a few days to learn Ember and not insert one of a dozen alternatives? Or should I take a few days for each of the dozens of newfangled alternatives that pop up every year? Are a few days even enough when you want to truly experience whether some framework is worth it?

Get off my lawn.
