Disagree with learning a new language everyear. I’ve found it’s far more marketable in a profession where new technologies arise and die rapidly to learn and build deep proficiency in a fewer languages that meet the demands of the market. Plus, languages share traits with one another—making it likely that if you know one language deeply, you’ll be able to work in another without much difficulty—Ruby vs Python for instance. By mastering the language you work in, you’re learning to use other similar languages as well. There’s also a bunch of trendy crap in the tech world that is a waste of time to learn. In the end, we’re all in this field for the money—that’s what careers are all about. Use your time wisely and maximize your value.

Some are, others aren't, human motives are not this simple.
