The sense of "meaning" in work is sensory, it isn't rationalized. The most effective utilitarian job in the world won't feel meaningful if you don't like the work. If your job affords deep flow, few interruptions and adequate social interaction, you'll be hard-pressed to get a better environment. Maybe you're bored with your tasks. Our monkey brains light up when the right circumstances surrounding work are there. If the whole sector leaves you jaded now, then best find some refuge in pet projects.

I was always someone more interested in the ends, the ideas, and immediately lose interest when it came to the prospect of implementation. To an extent it's still in my nature, but I've learned the hard way you have to start appreciating the means for their own sake; the abstractions to justify them don't necessarily matter. If you dwell on them long enough you'll convince yourself they're bs anyway and not necessary. Nothing is "necessary".
