I kid you not, I am about to start learning more about compilers to myself. I would like to write my own, and I have a few resources to dive into which I hope will help. I am not trying to make the next LLVM or anything, but I hope writing a rather simple compiler would better my current (lack of) understanding of compilers.

I am going to assume that you are much further along in your career than I am. Not perhaps in years of experience, but rather more in terms of literal career progression. I'm just a small shop code-monkey, so there isn't really any verticality to my position (unless I jump ship).

However, I do sympathize with your questioning the worth of it all. In some ways, I think I have prematurely questioned many of the same ideas. Such questioning has perhaps aided in my procrastination in bettering my situation.

Maybe what I am looking for is purely fantasy and does not exist in a truly feasible manner? I mean, we have only one life on this planet. I often find myself questioning if this is how I one to spend such time. . .

Early 30s was around the age I started self-teaching compilers. Great time to learn, and the urge to improve one's lot is one of the best fires in the belly you can have.

I felt those same things. Places where quality work is respected do exist, but they may not be in FAANG. You may need to choose between interesting work and money eventually.

Happy to chat more over email if it is helpful.
