I hear you there. I actually used to be an out of control Ruby hater - until I read Eloquent Ruby (fantastic book, my all time fav programming book) and started to understand it from first principles and all the beauty of message passing. I was Ruby-only for a few solid years of my career.
The quicker a young engineer can table that kind of unsubstantiated bias the better. Then again that could go for all aspects of life!
