JIRA is one of those pieces of software that creates more problems than it solves. That's good for the industry -- it means to get an equivalent amount of work done, you need more people. More jobs competing for the same pool of workers means that you have to pay the workers more. That's good for everyone.
(If I were starting a company tomorrow, though, I'd use Linear. Nicest issue tracking tool I have ever seen. It has all the "big business" features like roadmaps and story points, with a lot of friendliness for the individual contributors -- dark mode, keyboard shortcuts, a dedicated triage UI. It's so nice to see someone finally get it right!)
