Yes, but none of this is really specific to web development. It's just the nature of being a technologist. It's really a balancing act of picking the latest and greatest vs. picking the tried and tested. No one wants to learn something that'll be useless in a year. Alternatively if you forego learning anything new then you'll miss out on technologies that can actually help you. For me, I don't really view learning things as wasted time. Even if I don't use some technology I learned a year or two ago, there's plenty of valuable lessons that can be learned from why things didn't work out. It would get frustrating if I were learning all the wrong things all the time. So, I focus on the things that genuinely get me excited followed shortly by new technology that isn't completely fresh.
