The treadmill of new technologies and constant change and learning won't go away. It would be one thing if your boss was an asshole or the company was bad, that could be fixed by a new job, but if you just have no natural affinity for the work, forcing yourself to do it for the money will lead you quickly to severe burnout, depression, etc.
People can usually do better in a field that seems stagnant but they have a passion for and enjoy than they will in a hot field that they don't like.
