Also, OP, maybe look into building an operating system from first principles like that dude who made the tetris OS [0] or look into creating a nice collection of curated OS VM snapshots that demonstrate the things you're into in a running environment with tools like LXC/LXD [1] ( these days it's surprisingly easy to share VMs running with very detailed emulated specs running connected to a web browser) or look into taking the time to assemble one of those kits that lets you build a historic processor with LEDs and transistors on a bread board [2]. Or if you just like reading about it, even just keeping a journal or private wiki will I think make it so it gains personal context. Also, you like what you like. If it's not really hurting you to have a hobby about loving the history of OSs, I know some folks that are pretty encyclopedic about the inside baseball of pro wrestling or star trek. Hunt your bliss.
For what it's worth, I'm pretty sure your insights into the things your reading is something I'd enjoy reading or exploring. If/when you figure out how you want to share that, I hope to see it and I can dig in and read or watch every entry and ignore what I'm really supposed to be doing in a day and bore my girlfriend with the details. I think possibly this is just describing how human history is assembled after it's done being the human present.

Also, it sounds like you enjoy thinking/learning about OSs, so saying it doesn't benefit you in any meaningful way sounds strange to me. As if your happiness means nothing. Maybe think about what's really important in life.
