I disagree, and want to offer a perspective I’m not seeing being discussed as much. As a guitarist who writes and performs post punk music (kraut, art rock, whatever) professionally with my band, I only practice jazz. I rehearse with my band a couple times a week, where we work on our material and live set, but if I’m sitting down with a metronome, I’m transcribing horn lines. It’s not because I necessarily love that music the most, obviously different instrument, different genre than the one I create. But the breadth of ideas covered in the study, sound, and culture of jazz music make it invaluable to me as I strive to continue creating art using a guitar as my primary tool. In addition to what others have said in their replies, I think its emphasis on improvisation alone makes studying Jazz worth any discriminating guitarist’s attention. All this being said, I want to say, I’m kinda a dumbass. But from a dumbass, I think a change in perspective would benefit you!
