Actually I’m with @diskwaveon this one. Not because you’ll always be stuck in pub bands or can’t play jazz, because I don’t think that’s the case, but because knowing how to read dots opens up a lot of learning opportunities and also because it’s the language of what we do, so seems like an appropriate thing to do. Also, not that hard to learn, like anything you’re doing it just takes practice and although frustrating at first, is rewarding when you get there. I’ve just picked up some etudes and classical pieces to study purely to learn and expand on some harmony/melodic concepts and the only format is notation. You could always incorporate learning to read as part of the overall musical journey you’re on, which could be fun. But as others have also said, it’s not by any means strictly necessary.
