You're probably being sarcastic but I think the parent meant Curriculum Vitae. Making technical decisions based on what will look good on your resume instead of what's the best way to solve the problem at hand.
As a contractor, I was compelled to learn those technologies because the companies were demanding these skills, not because I had a desire to learn another scripting language or whatever. Of course, it's often (senior) developers within the company that push the new, less-well-travelled technologies and the cycle repeats.
I guess the lesson is, don't let frontend developers dictate that JavaScript should be on the server, or is in fact a good language for desktop apps and so on.
